Technical Field

The present application relates to the field of computer technologies, and in particular, to a method and an apparatus for service grouping based on a multi-tenant service.

Multi-tenant is an architecture technology that can implement sharing the same system or program component in a multi-user environment and still ensure isolation of data between users. Wherein each user may be referred to as a tenant. With the development of multi-tenant technology, more and more services, such as distributed databases, cloud computing platforms, etc., which can be oriented to multi-tenancy appear.

Generally, for a multi-tenant service, it can provide services to services of different scenarios. However, in practical applications, since service requirements of different services are different, for example, different services have different requirements on delay, user access error rate, throughput, and the like, peak-to-valley times between services are different, so that interference may be generated between different services, thereby affecting service quality of the services.

Detailed Description

In the existing multi-tenant Service, SLA (Service-Level agent, service Level Agreement) defines indexes of access error rate, delay and the like of a Service, and can be used for measuring Service quality of the Service. When providing services to services of different scenes, the multi-tenant service needs to ensure that the services have stable SLAs.

However, in practical applications, due to different service requirements of different services, interference may occur between different services, thereby affecting SLA and reducing service quality for the services. For example, the same resource may provide services for two or more services simultaneously in a certain period of time, so that interference may occur between different services due to the simultaneous use of the same resource between different services, thereby affecting SLAs of the services and reducing quality of service for the services.

In order to avoid interference between different services, it is common in the prior art to isolate each service individually or to manually group multiple services. Wherein:

each service is isolated independently, namely the same resource only serves one service, so that the condition that the same resource provides services for different services at the same time can be avoided, and the interference among the services can be reduced to the minimum. However, this method is equivalent to a single tenant mode, the resource utilization rate is low, and when the capacity of the service resource needs to be expanded, the process of expanding the capacity is relatively complex.

The multiple services are manually grouped, different services can be distributed to different groups according to service requirements, and different groups correspond to different resources. The manual grouping method can solve the problem of interference between services to a certain extent. However, in practical applications, the manual grouping method generally has hysteresis and poor grouping flexibility, and cannot fundamentally solve the problem of interference between services.

In view of this, an embodiment of the present application provides a method and an apparatus for service grouping based on a multi-tenant service, where the method includes: determining access characteristic information of a first service, wherein the first service belongs to a tenant; determining a first group matched with the first service according to the access characteristic information, wherein the first group corresponds to a first resource; and allocating the first service to the first packet, wherein the access index and the resource utilization rate of the first packet including the first service meet preset conditions, and the preset conditions are used for representing that the first resource corresponding to the first packet meets the service requirement of the first service.

The technical scheme provided by the embodiment of the application can at least achieve the following beneficial effects:

(1) When the service is provided, the service is intelligently distributed to the matched groups, and the service is provided by the resources corresponding to the groups, so that the interference of the service among different groups can be avoided;

(2) In the same group, as the access index and the resource utilization rate of the group can meet the service requirement of the service, the stable service can be ensured to be provided for the service, thereby improving the service quality of the service;

(3) After the service is distributed to the matched groups, the resource utilization rate in the groups can be monitored, and when the resource utilization rate in the groups is higher, the groups can be expanded or the service can be regrouped, so that stable service can be provided for the service; when the utilization rate of resources in the packet is low, the resources in the packet can be released, so that the service in the packet is ensured to have stable SLA and reasonable resource utilization rate;

(4) The resource utilization rate of the resources corresponding to the default grouping can be monitored, and when the resource utilization rate is high, the capacity expansion of the resources grouped by default can be carried out in advance, so that the capacity expansion of the multi-tenant service is realized. Therefore, by expanding the multi-live service, sufficient resources can be provided for the service conveniently, and the service is ensured to have stable SLA;

(5) After determining the access characteristic information of the service, the multi-tenant service can also feed back the access characteristic information to the tenant (namely, a service party), and can also provide an improvement suggestion and the like for the service, so that a user can adjust the requirement of the service, and the SLA of the service is further prevented from being influenced by the hot spot of the service;

(6) In the embodiment of the application, the whole process of allocating the service to the matched group and monitoring the resource utilization rate in the group is a full-automatic process, and the whole process has the advantages of real-time grouping and predictability of the resource utilization rate, so that compared with manual grouping, the method is more efficient and real-time, and can effectively solve the problem of interference between services.

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making creative efforts shall fall within the protection scope of the present application.

The multi-tenant service described in the embodiment of the present application may be a distributed cloud service or a distributed database, where the distributed database may specifically be an NOSQL (Not Only SQL (Structured Query Language)) database, that is, a non-relational database. For convenience of understanding, the embodiments of the present application may be described by taking a multitenant service as a distributed NOSQL database as an example.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1 is a flowchart illustrating a method for grouping services based on a multi-tenant service according to an embodiment of the present application. The embodiment of the present application takes a multi-tenant service as a multi-tenant based distributed database (hereinafter referred to as a database) and groups a first service, where the first service belongs to a tenant (may be regarded as a user). The grouping method is as follows.

S102: access characteristic information of the first service is determined.

In S102, after determining the first service of the user, the database may determine access characteristic information of the first service.

The access characteristic information may characterize a service attribute of the first service, and the access characteristic information may be used to determine a packet matching the first service.

In an embodiment of the present application, the access characteristic information may specifically include at least one of the following: the service type of the first service, the resource required by the first service, the query rate QPS, the delay, the access amount, whether the access performance of the first service among the partitions is stable or not and the peak time period; a peak duration; CPU utilization rate, memory utilization rate and disk utilization rate.

The service type of the first service may include: off-line service, on-line service, and combined off-line and on-line service; the resource required by the first service can be understood as the minimum resource capable of providing service for the first service; the delay may be a delay in a unit time or an average delay in a set time period when the first service accesses the database.

It should be understood that the above-mentioned access characteristic information is only a preferred embodiment of the present application, and in other implementations, the access characteristic information may further include other information, which may be specifically determined according to the actual first service, and is not illustrated here.

In the embodiment of the present application, when determining the access characteristic information of the first service, the database may be determined and obtained by at least one of the following methods:

the first method comprises the following steps: providing service for the first service by using the resource corresponding to the default grouping; and acquiring access data of the first service, and determining access characteristic information of the first service according to the access data.

The second method comprises the following steps: determining access characteristic information of the first service provided by the tenant.

For the first method described above:

after receiving the first service of the user, the database may provide a service for the first service by using a resource corresponding to a default packet in the database when providing the service for the first service. The default grouping may be understood as an initial grouping of resources in the database, all resources in the database may belong to the default grouping before no service is isolated by the grouping, and after the service is isolated by the grouping, other resources except the resources isolated by the grouping may belong to the default grouping. In practical applications, each multi-tenant based database may contain default groupings.

In the process of providing a service for the first service by using the resource corresponding to the default packet, access data of the first service may be observed and collected, where the access data may be understood as detailed access information of the first service, and the access data may be used to determine to obtain the access characteristic information.

When acquiring the access data of the first service, an acquisition period may be set, where the acquisition period may be a day, a week, or the like, and may be determined specifically according to an actual situation, and is not specifically limited herein. The access data may be access data in one acquisition cycle, or average access data corresponding to multiple acquisition cycles.

After the access data is acquired, the access data can be subjected to processing such as summary analysis, and finally the access characteristic information can be determined.

In this embodiment of the application, the access characteristic information determined and obtained according to the access data may include: the service type of the first service, the resource required by the first service, the query rate QPS, the delay, the access amount, whether the access performance of the first service between the partitions is stable, at least one of a peak time period, a peak duration, a CPU usage rate, a memory usage rate, and a disk usage rate.

For the second method described above:

the database may provide a platform for interacting with different users (i.e., tenants), which may be considered a console. In the embodiment of the application, a user can create an instance of the first service in the console, and when the instance is created, the user can provide access characteristic information of the first service through the console according to the known service requirement of the first service.

In this embodiment, the access characteristic information provided by the user may include: at least one of a traffic type of the first traffic, a resource required for the first traffic, an amount of access, a peak time period, and a peak duration.

In practical applications, the access characteristic information may be determined and obtained based on any one or two of the above methods, and specifically, which method is to be selected may be determined according to practical situations, which is not specifically limited herein.

Preferably, in consideration of the fact that in practical applications, the access characteristic information provided by the user may be inaccurate, and the access characteristic information determined according to the access data may also be incomplete, the access characteristic information may be determined by using the above two methods, that is, the access characteristic information determined according to the access data and the access characteristic information provided by the user are combined to obtain final access characteristic information. Therefore, the accuracy of the access characteristic information is high, and when the grouping matched with the first service is determined according to the access characteristic information subsequently, the accuracy of the grouping obtained through matching can be improved.

In an embodiment of the present application, if the access characteristic information of the first service is determined by the first method described above, after the access characteristic information is determined, the access characteristic information may be fed back to the user through the console described above, so that the user may adjust the service requirement of the first service.

Preferably, before feeding back the access characteristic information to the user, it may first be determined whether the access characteristic information provided by the user is consistent with the access characteristic information determined from the access data of the first service (since the access characteristic information provided by the user may be erroneous).

If the access characteristic information is inconsistent with the service requirement of the first service, the access characteristic information can be fed back to the user, and meanwhile, some improved suggestions and the like can be fed back to the user, so that the user can adjust the service requirement of the first service according to the fed-back access characteristic information and the improved suggestions. If the access characteristic information is consistent with the access characteristic information, the user can be selected to be fed back, and the user can also be selected not to be fed back with the access characteristic information.

For example, after determining the access characteristic information according to the access data of the first service, if it is found that the first service has an access hotspot according to the access characteristic information, and the duration of the hotspot is longer and is different from the access characteristic information provided by the user, the access characteristic information determined according to the access data and a suggestion for adjusting the service requirement of the first service may be fed back to the user, so that the user may adjust the service requirement of the first service based on the fed-back suggestion, thereby preventing the first service from affecting the SLA of the service due to the hotspot itself.

In S102, after determining the access characteristic information of the first service, S104 may be performed.

S104: and determining a first group matched with the first service according to the access characteristic information.

After determining the access characteristic information of the first service, a first packet matching the first service may be determined, and the first packet may correspond to a first resource in a database in S104. Wherein the "first" in the first group and the "first" in the first resource are used only for distinguishing from other groups and resources, and have no other special meaning.

In this embodiment of the present application, when determining the first packet matching the first service, if the resources in the database are not isolated by the packet (that is, the database in the initial state does not include the isolated packet, and all the resources in the database belong to a default packet), determining that the first packet matching the first service may be to create a packet for the first service according to the access characteristic information, where the packet may correspond to the first resource in the database, and the first resource may provide a service for the first service, where the packet is the first packet.

When creating a group for the first service, a part of resources can be selected from the resources of the default group as a group, wherein when selecting the resources, it is required to ensure that the selected resources can meet the service requirements of the first service, so that the first service can have a stable SLA, and in addition, it is also required to ensure that the resource utilization rate of the resources is not too high when the part of resources provides services for the first service, so as to ensure that the group has a reasonable resource utilization rate.

If the database contains the isolated at least one packet, determining a first packet matching the first service may include:

matching the access characteristic information with the grouping characteristic information of the existing grouping;

and if the matching is successful, determining the group corresponding to the group characteristic information matched with the access characteristic information as the first group.

Specifically, after isolating the resources in the database and obtaining one or more groups, the resource usage of each group may be analyzed to determine group feature information of each group, where the group feature information may be the same as the access feature information of the first service, and specifically, reference may be made to the description of the access feature information in S102, and a description thereof is not repeated here.

After the grouping feature information of each group is determined, that is, after a corresponding tag (tag) is determined for each group, a mapping relationship between the grouping feature information and the group can be established.

In this way, when the first packet matching the first service is determined, the access characteristic information of the first service may be matched with the packet characteristic information in the mapping relationship, and if the matching is successful, the packet corresponding to the packet characteristic information matching the access characteristic information of the first service may be determined, and the packet may be determined as the first packet matching the first service.

For example, when it is determined that the first service is an online service with low latency and few access hotspots according to the access characteristic information of the first service, if a packet of the online service with low latency and few access hotspots exists in an existing packet, the packet may be regarded as a first packet matching the first service.

When the access characteristic information of the first service is matched with the packet characteristic information in the mapping relationship, if the matching is not successful, it can be stated that the existing packet does not include a packet matched with the first service, and then:

in one implementation, a new packet may be created for the first service based on the access characteristic information of the first service, and the packet may be regarded as the first packet. For the method for creating a packet for the first service, reference may be made to the above-mentioned method for creating a packet for the first service when the database does not group resources. The description is not repeated here.

For example, when it is determined that the first service is an offline service with low latency and few access hotspots according to the access characteristic information, if the packet characteristic information of the existing packet corresponds to the online service, a new packet may be created for the first service based on the service characteristics of the offline service with low latency and few access hotspots of the first service, where the new packet is the first packet matched with the first service.

For another example, if the first service requires more resources and cannot share a packet with other services, a new packet may be created for the first service to isolate the first service from other services. Wherein the packet created for the first service is the first packet.

In another implementation, if the matching is not successful, the first service may be served by a resource corresponding to the default packet, that is, the default packet is used as the first packet.

In the process of providing services for the first service by using the resource corresponding to the default packet, the access characteristic information of the first service can be determined again, and the first packet matched with the first service is determined again based on the determined access characteristic information.

In S104, after determining the first packet matching the first service, S106 may be performed.

S106: allocating the first traffic into the first packet.

After determining a first packet matching the first service, the first service may be allocated to the first packet in S106. The following description will take the first packet as an existing packet as an example.

In the embodiment of the application, after the first service is allocated to the first group, the access index and the resource utilization rate of the first group including the first service can meet preset conditions. The access index may be an SLA (service level agreement), that is, an access error rate, a delay and other indexes, the resource utilization rate may be a utilization rate of a resource corresponding to a first group when the first group provides a service for a plurality of services including the first service, and the preset condition may be used to represent that a first resource corresponding to the first group may meet a service requirement of the first service.

The access index meeting the preset condition may be that the access index is not greater than a set index, the resource utilization rate of the first group meeting the preset condition may be that the resource utilization rate of the first group is not greater than a set threshold, and the set index and the set threshold may be determined according to an actual situation, which is not specifically limited herein.

After the first service is allocated to the first group, the first group can enable the access index and the resource utilization rate of the first group to meet the preset conditions in a load balancing mode, so that interference among different services in the group is avoided, and each service is guaranteed to have a stable SLA.

In an embodiment of the present application, in order to ensure that the resource usage rate of the first packet including the first service meets the preset condition, when the first service is allocated to the first packet, a resource may be further added to the first packet, and the added resource may be a resource required by the first service. In this way, since the resource required by the first packet is added to the first packet while the first service is allocated to the first packet, it can be ensured that the resource usage rate of the first packet can satisfy the preset condition after the first service is allocated to the first packet. Wherein the resources added in the first packet may be from a default packet.

Based on the technical scheme provided by the embodiment of the application, the services with the matched access characteristic information can be distributed into one group by intelligently grouping the services, so that the interference between the services in the group can be avoided, and the interference between the services in different groups can also be avoided.

It should be noted that, because the service requirements of the online service and the offline service are greatly different, in order to avoid interference between services in a packet, when grouping the services, it is necessary to avoid that the online service and the offline service share one packet.

For example, online traffic with relatively smooth access and few hot spots may be assigned to one packet, offline traffic with significantly staggered traffic peaks may be assigned to one packet, and traffic with frequent access to hot spots may be assigned to one packet individually. Each group can correspond to different resources, so that the interference of services among different groups can be avoided due to different resources for providing services for the services in different groups.

It should be further noted that, after the first service is allocated to the first packet, the packet characteristic information of the first packet will change, and at this time, the changed packet characteristic information may be determined, so that when a packet is subsequently allocated to a new service, a packet matching the new service may be further determined according to the changed packet characteristic information and the access characteristic information of the new service.

In one embodiment of the present application, after the first service is allocated to the first packet matching therewith, the method further includes:

monitoring a first resource usage of the first packet;

when the first resource utilization rate is greater than a first preset threshold value, generating first prompt information so as to expand the first packet according to the first prompt information;

and when the first resource utilization rate is smaller than a second preset threshold value, releasing the set resource in the first group according to the first resource utilization rate.

Specifically, after the first service is allocated to the first packet, the resource utilization of the first packet may be monitored in real time, so as to determine the service condition of the first packet as the first service in real time. To facilitate differentiation from the resource usage of other packets, the resource usage of the first packet may be referred to herein as the resource usage of the first packet.

After the first resource usage of the first packet is obtained through monitoring, whether the first resource usage is too high may be determined. Specifically, the first resource utilization rate may be compared with a first preset threshold, and whether the first resource utilization rate is greater than the first preset threshold is determined, if yes, it may be said that the resource utilization rate in the first group is too high; if not, the first resource utilization rate can be determined to be more reasonable.

The first preset threshold may be determined according to an actual traffic type, for example, if the traffic in the first packet is an offline traffic, the first preset threshold may be higher, for example, between 40% and 60%, because the offline traffic has a smaller access amount during non-computation periods and is not particularly sensitive to delay, and the throughput is weighted; if the traffic in the first packet is online traffic, the first preset threshold may be lower, for example, between 20% and 40%, since online traffic is sensitive to delay. Of course, the specific size may be determined according to actual conditions, and is not specifically limited herein.

In an embodiment of the present application, when the first resource utilization is too high, the first prompt information may be generated, so that capacity expansion may be performed on the first packet according to the first prompt information, thereby reducing the resource utilization of the first packet.

The first prompt information may be a voice prompt, a text prompt, or the like, and is not limited in this respect.

In another embodiment of the present application, when the first resource usage is too high, the method may include:

re-determining access characteristic information of the first service;

determining a second packet matched with the first service according to the redetermined access characteristic information, wherein the second packet corresponds to a second resource;

and allocating the first service to the second packet, wherein the access index and the resource utilization rate of the second packet including the first service meet the preset conditions.

Specifically, when the first resource usage is too high, it may be indicated that the first service is not suitable for allocation into the first packet, and at this time, the first service may be moved out of the first packet and provided with a common service by a default packet.

When the first service is served by the default packet, the access characteristic information of the first service may be re-determined according to the access data of the first service. After the access characteristic information of the first service is re-determined, the packet matching the first service may be re-determined according to the above-described method based on the access characteristic information, where the second packet represents the re-determined packet of the first service.

The second packet may correspond to a second resource, and after determining the second packet, the first traffic may be allocated to the second packet and serviced by the second resource corresponding to the second packet. After the first service is allocated to the second packet, the access index and the resource utilization rate of the second packet including the first service may satisfy a preset condition, where the preset condition may be used to represent that the second resource corresponding to the second packet satisfies the service requirement of the first service.

Therefore, after the first service is allocated to the first packet, the service condition of the first service can be determined by monitoring the first resource utilization rate of the first packet, and if the first resource utilization rate is too high, the capacity of the first packet can be expanded, or the allocation packet can be re-determined for the first service. Therefore, the resources for providing services for different services in the first packet are ensured not to conflict with each other, and stable services are provided for the first service in real time.

For example, when it is determined that the number of access hot spots of the first service in the first packet is large or the resource usage rate is too high due to resource conflict with other services according to the access data, capacity expansion may be performed on the first packet, or it may be determined that the first service is not suitable for being allocated to the first packet, and a suitable packet is newly allocated to the first service.

In the embodiment of the application, after the first resource utilization rate is obtained through monitoring, whether the first resource utilization rate is too low can be further judged. Specifically, the first resource utilization rate may be compared with a second preset threshold, and whether the first resource utilization rate is smaller than the second preset threshold is determined, if yes, it may be stated that the first resource utilization rate is too low, and if not, it may be stated that the first resource utilization rate is more reasonable. The second preset threshold is smaller than the first preset threshold, and may be specifically determined according to an actual situation.

When it is determined that the first resource usage is too low, the set resource in the first packet may be selected to be released in order to increase the resource usage. The set resource may be determined according to the first resource usage rate, and is not particularly limited herein. When the provisioning resources are released, the provisioning resources may be released into a default packet.

In the embodiment of the application, for the existing packets in the database, the resource utilization rate can be monitored according to the method described above, and once the resource utilization rate is found to be too high, the packets can be expanded or a certain service in the packets can be moved out of the packets and matched packets can be determined for the moved packets again; once the resource utilization rate is found to be too low, the resources in the packet can be released to ensure that the service in the packet has a stable SLA and reasonable resource utilization rate.

In the embodiment of the application, besides monitoring the resource utilization rate of the existing group in the database, the resource utilization rate of the database can be monitored. In particular, resource usage of resources of a default grouping in the database may be monitored. To facilitate differentiation from the resource usage of the packet, the resource usage of the default packet may be made by the second resource usage.

After the second resource usage rate of the default packet is monitored, whether the second resource usage rate is too high may be determined, specifically, the second resource usage rate may be compared with a third preset threshold, and whether the second resource usage rate is greater than the third preset threshold may be determined.

When the second resource utilization rate is too high, second prompt information can be generated, so that capacity expansion can be performed on the default grouped resources according to the second prompt information, namely capacity expansion can be performed on the database. Therefore, the database can provide more stable service for a plurality of services, and resource conflict is avoided.

The third preset threshold may be determined according to actual conditions, and the second prompt information may be a voice prompt or a text prompt, which is not specifically limited herein.

In this embodiment of the present application, the default grouping may play a role in resource buffering for the database, specifically: when a new service needs to be allocated to a group, the service can be provided by using the resource in the default group, the access characteristic information of the service is determined, and then the group is created for the service according to the access characteristic information. When creating a packet, the resources within the packet come from a default packet.

When other packets need to be created, the resources of the other packets are also from the default packet. The default packet will always exist in the database. When the resource utilization rate of other groups is too high, the capacity of other groups can be expanded by using the resources in the default group, and when the resource utilization rate of other groups is too low, partial resources of other groups can be released to the default group.

When the resource utilization rate of the default grouping is too high, the capacity expansion of the database can be realized by performing capacity expansion on the default grouping.

It should be noted that, because the packet expansion can be completed within the minute level, the time spent on expanding the database is long, and purchasing and moving may be involved, and the like, the expansion of the database needs to be predicted in advance, that is, whether the expansion of the database needs to be performed may be predicted according to the second resource usage rate of the default packet.

According to the technical scheme provided by the embodiment of the application, when the service is provided, the service can be intelligently distributed to the matched groups by determining the access characteristic information of the service, and then the service is provided by the resources corresponding to the matched groups. Therefore, by intelligently grouping the services, the interference of the services among different groups can be avoided; in the same group, because the access index and the resource utilization rate of the group can meet the service requirement of the service, stable service can be provided for the service, and the service quality of the service is improved. The whole process of the embodiment of the application is automatic, and the high efficiency and the real-time performance of grouping the services can be ensured.

In addition, after the service is distributed to the matched groups, the resource utilization rate in the groups can be monitored, when the resource utilization rate in the groups is higher, the groups can be expanded or a certain service in the groups can be grouped again, when the resource utilization rate in the groups is higher, the resources in the groups can be released, and therefore the service in the groups can be ensured to have stable SLA and reasonable resource utilization rate; the resource utilization rate of the default grouping can be monitored, and when the resource utilization rate of the default grouping is high, the capacity expansion of the resource of the default grouping can be performed in advance, so that sufficient resources can be provided for services, and the services are guaranteed to have stable SLAs.

In the embodiment of the application, the whole process of allocating the service to the matched group and monitoring the resource utilization rate in the group is a full-automatic process, and the whole process has the advantages of real-time grouping and predictability of the resource utilization rate, so that compared with manual grouping, the method is more efficient and real-time, and can effectively solve the problem of interference between services.

To facilitate understanding of the whole technical solution, see fig. 2. Fig. 2 is a flowchart illustrating a service grouping method based on a multi-tenant service according to an embodiment of the present application. Fig. 2 illustrates an example of a multi-tenant based database. The method is as follows.

S201: determining access characteristic information of a first service provided by a user.

The multi-tenant database may provide a console as an interactive platform with users (tenants) in which the users may create instances of the first service and provide access characteristic information for the first service.

The user-provided access characteristic information may include at least one of: a service type of the first service; a resource required by the first service; a visit amount; a peak time period; the peak duration.

S202: the first traffic is assigned to a default packet.

The default grouping may be understood as a grouping of resources in the database except for the resources isolated by the grouping. The purpose of assigning the first service to the default packet is to determine access characteristic information of the service in order to assign the first service to the matching existing packet.

S203: and acquiring access data of the first service, and determining access characteristic information of the first service according to the access data.

When the default packet provides a service for the first service, the access data of the first service may be observed and collected, and the access characteristic information of the first service is determined according to the access data, where the access characteristic information is the same as the access characteristic information described in S201.

S204: and determining a first group matched with the first service according to the access characteristic information.

The access characteristic information in S204 may be a combination of the access characteristic information provided by the user in S201 and the access characteristic information determined by the collected access data in S203. The first service corresponds to a first resource in a database.

When determining the first packet matching the first service, the specific implementation method may refer to the contents described in the embodiment shown in fig. 1, and a description thereof is not repeated here.

S205: allocating the first traffic into the first packet.

The access index and the resource utilization rate of the first packet including the first service meet preset conditions, and the preset conditions are used for representing that the first resource corresponding to the first packet meets the service requirement of the first service.

When the first service is allocated to the first packet, the resource required by the first service may be further added to the first packet, so as to ensure that the resource usage rate of the first packet may meet the preset condition. After the first service is allocated to the first packet, the first service may be served by resources in the first packet.

S206: a first resource usage of the first packet is determined.

S207: and judging whether the first resource utilization rate is greater than a first threshold value.

The first threshold may be equal to the first preset threshold described above. If the first resource utilization rate is greater than the first threshold, it may be determined that the first resource utilization rate is too high, and at this time, S208 may be performed; otherwise, S206 may be executed, i.e., the monitoring of the first resource usage is continued.

S208: and generating first prompt information so as to expand the first packet according to the first prompt information.

S209: and determining a second resource utilization rate of the resource corresponding to the default grouping.

S210: and judging whether the second resource utilization rate is greater than a second threshold value.

The second threshold value may be equal to the third preset threshold value described above. If the second resource usage rate is greater than the second threshold, it may be indicated that the second resource usage rate is too high, and at this time, S211 may be executed; otherwise, S209 may be executed, i.e., the monitoring of the second resource usage is continued.

S211: and generating second prompt information so as to expand the default grouping according to the second prompt information.

It should be noted that the access characteristic information in S204 may also be the access characteristic information provided by the user in S201, that is, the first service is directly grouped according to the access characteristic information provided by the user, or may also be the access characteristic information determined by the acquired access data in S203, that is, the first service is grouped only according to the actually observed access characteristic information.

In S203, after the access characteristic information is acquired, feedback may also be performed to the user, so that the user can adjust the service requirement of the first service.

S206 and S209 may be executed simultaneously, that is, while monitoring the resource usage of the first packet, the resource usage of the default packet may also be monitored.

In S207, if the first resource utilization is greater than the first threshold, the first packet may be further shifted out of the first packet, and a packet matching the first packet is determined again.

In addition, after the first resource utilization rate is determined, whether the first resource utilization rate is too low can be judged, if the first resource utilization rate is too low, a part of resources in the first grouping can be released to the default grouping, and therefore the utilization rate of the resources in the first grouping is improved.

In the embodiment shown in fig. 2, when providing services for services, services are allocated to matched packets, and then resources corresponding to the packets provide services for the services, so that interference of services between different packets can be avoided; in the same group, the resource utilization rate in the group is monitored, so that the interference between different services in the same group can be avoided, stable service is guaranteed to be provided for the different services, and the service quality of the services is improved.

In addition, the resource utilization rate of the first packet and the resource utilization rate of the default packet are monitored, and a prompt is generated when the resource utilization rate is high, so that the capacity expansion of the first packet and the default packet is facilitated, and therefore the service can be guaranteed to have stable SLA and reasonable resource utilization rate. The whole process is automatic, and is more efficient and real-time compared with manual grouping.
