Detailed Description

The technical solution of the present application is further described in detail with reference to the drawings and specific embodiments of the specification.

Fig. 1 is a schematic view of a first flowchart implementation of a cloud data access method in the present application, as shown in fig. 1, the method includes:

step 101, determining a first physical available area corresponding to a service resource in the cloud server system and a plurality of second physical available areas corresponding to a target resource in the cloud server system;

in the application, the method can be applied to a cloud server system, the cloud server system is generally divided into a plurality of physical usable areas, and each physical usable area can store the same resource or different resources. The plurality of service resources established on the cloud server system may also distribute backup resources of each service resource in different physically available areas of the cloud server system. Therefore, when one service resource is abnormal or damaged, the service resource is distributed in different physical available areas, so that the service resources in other physical available areas cannot be unavailable due to the same accident. In this way, by placing the service resources in different physical available areas after being backed up with each other, the high available service of the system can be ensured. Here, since the cloud server system may generally run on a cloud server, the method may also be applied to the cloud server.

Specifically, when a service resource (e.g., the service component 1) in the cloud server system wants to access a target resource (e.g., a resource of the service component 2), a first physical available area corresponding to the service resource in the cloud server system and a plurality of second physical available areas corresponding to the target resource in the cloud server system need to be determined, and then an optimal target resource needs to be determined according to a topological relationship between the first physical available area and the plurality of second physical available areas. Here, the optimal target resource may refer to a resource that uses the least network cost and the highest network speed in the access path.

In the application, when the cloud server system determines that the service resource is in the corresponding first physical available area in the cloud server system, the cloud server system may specifically query the first physical available area information of the service resource in the cloud server system by sending a service distribution query instruction to the cloud management platform; here, the service distribution query instruction usually carries service information; for example, the service information includes, but is not limited to, a server name, a server IP address, and a server domain name. When the cloud management platform receives a service distribution query instruction sent by the cloud server system, first physical available area information corresponding to the service information can be queried from a cloud database according to the service information carried in the service distribution query instruction, and the first physical available area information corresponding to the service information is sent to the cloud server system. Here, the cloud management platform generally stores a correspondence between each service information and each physical usable area, and the first physical usable area information corresponding to the service information may be queried based on the correspondence. After receiving the first physical available area information corresponding to the service information sent by the cloud management platform for the service resource, the cloud server system may determine the first physical available area corresponding to the service resource in the cloud server system.

For example, the first physical usable area of the service resource in the cloud server system is the physical usable area a.

In this application, when determining the first physical available area corresponding to the service resource, the cloud server system may further determine by receiving a first notification message sent by the cloud management platform. Specifically, the cloud management platform may further send a first notification message for the service resource to the cloud server system according to a preset interval time, where the first notification message carries service information of the service resource and corresponding first physical available area information. For example, the service information of the service resource includes, but is not limited to, a server name and a server IP address. After the cloud server system receives a first notification message sent by the cloud management platform for the service resource, a corresponding first physical available area of the service resource in the cloud server system can be determined based on the first notification message.

For example, the service information carrying the service resource in the first notification message is service a and a physical available area a corresponding to service a. It may be determined that the corresponding first physical usable area of the service resource in the cloud server system is physical usable area a.

In this application, when the cloud server system determines that the target resource is in a plurality of second physically available areas corresponding to the cloud server system, the cloud server system may specifically send a target resource distribution query instruction to the cloud management platform according to a preset time interval, so as to query the plurality of second physically available areas corresponding to the target resource in the cloud server system; here, the target resource distribution query instruction carries target resource information. Here, the target resource information includes, but is not limited to, a domain name of the target resource, an IP address of the target resource. After receiving the target resource distribution query instruction sent by the cloud server system, the cloud management platform may query, according to target resource information carried in the target resource distribution query instruction, corresponding physical available area information in the cloud database, and send, to the cloud server system, a plurality of pieces of physical available area information queried for the target resource distribution query instruction. Here, the cloud management platform stores a corresponding relationship between each resource information and each physical available area, and the physical available area corresponding to the target resource information can be queried based on the corresponding relationship; the cloud server system receives a plurality of second physical available area information fed back by the cloud management platform based on the target resource information; and determining a plurality of second physical available areas corresponding to the target resource in the cloud server system based on the plurality of second physical available area information.

For example, if the plurality of second physical usable areas information is the physical usable area a, the physical usable area B, and the physical usable area C, it may be determined that the plurality of second physical usable areas corresponding to the target resource in the cloud server system are the physical usable area a, the physical usable area B, and the physical usable area C.

In this application, when determining that the target resource is in the plurality of second physically available areas corresponding to the cloud server system, the cloud server system may further determine through a second notification message sent by the cloud management platform. Specifically, the cloud management platform stores the corresponding relationship between each resource information and each physical available area; the cloud management platform can send a second notification message to the cloud server system according to the preset interval time, wherein the second notification message carries target resource information of the target resource in the cloud server system and a plurality of corresponding second physical available area information. The cloud server system receives a second notification message sent by the cloud management platform for the target resource, and a plurality of corresponding second physical available areas of the target resource in the cloud server system can be determined based on target resource information carried in the second notification message.

For example, the target resource information carried in the second notification message is a target resource a, and the plurality of second physical usable areas corresponding to the target resource a are a physical usable area a, a physical usable area B, and a physical usable area C. It may be determined that the plurality of second physically usable areas corresponding to the target resource in the cloud server system are a physically usable area a, a physically usable area B, and a physically usable area C.

102, establishing a topological relation between the first physical usable area and a plurality of second physical usable areas;

in this application, when the cloud server system obtains a first physical available area corresponding to the service resource in the cloud server system and a plurality of second physical available areas corresponding to the target resource in the cloud server system, the cloud server system may further establish a topological relationship between the first physical available area and the plurality of second physical available areas based on identification information, distance information, and/or idle state information between the first physical available area and the plurality of second physical available areas. The topological relation can be utilized to clearly know the current distribution conditions of the first physical available area where the service resource is located and each second physical available area where the target resource is located, and the optimal target resource can be conveniently selected from the plurality of second physical available areas for access.

Here, the identification information, the distance information, and/or the idle state information between the first physical usable area and the plurality of second physical usable areas may be information transmitted by the cloud management platform to the cloud server system according to a preset interval time. Alternatively, the cloud server system may send an inquiry request to the cloud management platform, and the cloud management platform receives the inquiry request and feeds back information to the cloud server system according to the inquiry request.

The identification information is used to characterize which physical available area the target resource and the service resource are located in, if the service resource and the accessed target resource are in different physical available areas, then the service resource will incur network cost when accessing the target resource, and the network transmission speed will be reduced by accessing data between different physical available areas. And the identification information is utilized to establish the topological relation between the first physical available area and the plurality of second physical available areas, so that the physical available areas corresponding to the service resources and the target resources respectively can be clearly known, and the target resources of the service resources and the target resources in the same physical available area are preferentially selected for access based on the identification information, so that the resource access speed can be improved, and the network cost is saved.

In addition, if the physical available areas where the service resource and the target resource are located are different, when resource access is performed between different physical available areas, the data transmission speed is generally slower the farther the distance is, and the network cost overhead is larger, conversely, when resource access is performed between different physical available areas, the data transmission speed is faster the closer the distance is, and the network cost overhead is smaller, so that by using the distance information between the first physical available area and the plurality of second physical available areas, the topological relation between the first physical available area and the plurality of second physical available areas is established, the distance information between the physical available areas can be clearly known, and thus the second physical available area closest to the first physical available area where the service resource is located is preferentially selected as the target physical available area based on the distance information, so that when resource access is performed between different physical available areas, the largest possibility saves network overhead cost and improves resource access speed.

Furthermore, if the physical usable areas of the service resource and the target resource are different and the distance between the different second physical usable area and the first physical usable area is far, when accessing the resource between the different physical usable areas, the network overhead cost for accessing the second physical usable area in an idle state is lower than that for accessing the second physical usable area in an active state, and the network speed is higher. Therefore, the topological relation between the first physical available area and the second physical available areas is established by using the idle state information between the first physical available area and the second physical available areas, and the current working states of the second physical available areas can be clearly known, so that the second physical available area in the idle state is preferentially selected as the target physical available area based on the idle state information, and thus, when resource access is performed between different physical available areas, the network overhead cost can be saved to the maximum extent and the resource access speed can be improved.

103, determining a target physical available area in the second physical available areas based on the topological relation and a preset strategy; the preset strategy at least represents a target resource which is preferentially selected to be located in the same physical available area with the service resource;

in this application, the cloud server system may generate a resource usage policy pool characterizing the service resource and the target resource based on a topological relation between the first physical usable area and the plurality of second physical usable areas; the resource usage policy pool may also be configured with resource weight information of each second physically available region. The resource weight information at least comprises a first weight factor representing the identification of each second physical available area, a second weight factor representing the distance between each second physical available area and the first physical available area, and a third weight factor representing the current use state of each second physical available area, wherein the weight of the same physical available area is the highest, and the weight of the same physical available area is the second highest and the weight of the idle state is the third highest. In this way, the cloud server system may select an optimal target resource for data access based on the resource weight information of each second physically available region configured in the resource usage policy pool.

Specifically, when determining the optimal target resource based on the resource weight information of each second physical available region configured in the resource usage policy pool, the cloud server system may determine, as the target physical available region, a second physical available region that represents that the target resource and the service resource are located in the same physical available region. And the target resource of the target physical available area is the optimal resource. Here because the network speed between the same physically available areas is the fastest and the network transmission is not charged.

In this application, when the cloud server system determines an optimal target resource based on the resource weight information of each second physical available region configured in the resource usage policy pool, if the resource weight information of each second physical available region configured in the resource usage policy pool represents that there is no available region that is the same as the first physical available region in the plurality of second physical available regions, the second physical available region that is the shortest distance from the first physical available region in the plurality of second physical available regions may also be determined as a target physical available region; this is because the shorter the distance between different physically available areas, the higher the network speed and the lower the charge for network transmission.

In this application, when the cloud server system determines the optimal target resource based on the resource weight information of each second physical usable region configured in the resource usage policy pool, if the resource weight information of each second physical usable region configured in the resource usage policy pool indicates that there is no usable region in the plurality of second physical usable regions that is the same as the first physical usable region, and the distance between the plurality of second physical usable regions and the first physical usable region is not much, the second physical usable region that is currently in an idle state may also be determined as the target physical usable region. And the target resource of the target physical available area is the optimal resource. This is because the network speed in the idle state is higher than the network speed in the active state when the distances between different physically available areas are close.

Therefore, the second physical available area meeting at least one condition is determined as the optimal target resource through the resource weight information of each second physical available area configured in the resource use strategy pool, and compared with a random scheme in the prior art, the network speed during data access between different physical available areas can be improved.

In addition, because the network speed between different physical available areas is lower than the network speed in the same physical available area, and in many cloud server systems, the network transmission between different physical available areas is charged, and the application preferentially selects the target resource in the same physical available area with the service resource to access, the speed of the internal network in the cloud server system can be improved, and the cost of the network cost can be reduced.

In this application, when the cloud server system determines the optimal target resource based on the resource weight information of each second physical available region configured in the resource usage policy pool, the second physical available region, which is located in the same physical available region as the service resource and is currently in an idle state, in the plurality of second physical available regions may also be determined as the target physical available region. And the target resource of the target physical available area is the optimal resource. This is because when the accessed target resource and the accessed service resource are located in the same physical available area, if the second physical available area where the target resource is located is currently in an idle state, it indicates that the second physical available area does not currently have access to other service resources, so the transmission speed of the network is faster.

In this application, when the cloud server system determines the optimal target resource based on the resource weight information of each second physical available region configured in the resource usage policy pool, if the target resource is different from the physical available region where the service resource is located, the second physical available region that is the shortest distance from the first physical available region and is currently in an idle state among the plurality of second physical available regions may also be determined as the target physical available region. And the target resource of the target physical available area is the optimal resource. This is because when the accessed target resource and the service resource are located in different physical available areas, if the second physical available area where the accessed target resource is located is the shortest distance from the first physical available area where the service resource is located and is currently in an idle state, it indicates that the current second physical available area has no access to other service resources and the network has the fastest time efficiency, so the transmission speed of the network can be increased and the network overhead cost can be reduced.

Therefore, the second physical available area meeting a plurality of conditions is determined as the optimal target resource through the resource weight information of each second physical available area configured in the resource use strategy pool, and compared with a scheme that the second physical available area meeting one condition is used as the optimal target resource, the speed of an internal network in the cloud server system can be further improved, and meanwhile, the cost of network cost can be further reduced.

Step 104, accessing the target resource in the target physical usable area.

In this application, when the cloud server system determines the target physical available area from the plurality of second physical available areas based on the topological relation and the preset policy, the target resource of the target physical available area may be accessed through a path between the first physical available area of the service resource and the target physical available area. Thus, the data flow speed can be greatly improved.

According to the cloud data access method, the physical available areas of the service resources and the target resources are respectively judged before data access, so that a plurality of physical available areas corresponding to the target resources are effectively selected in the cloud server system, the target resources in the same physical available area with the service resources can be preferentially selected for data access, the data flow speed can be increased, and extra network cost cannot be generated.

In this application, if a service resource fails to access a target resource in the target physical available area, it is determined that the current target physical available area is abnormal or damaged, which indicates that the current resource usage policy pool changes, the cloud server system needs to re-determine a first physical available area corresponding to the service resource in the cloud server system and a plurality of second physical available areas corresponding to the target resource in the cloud server system. And then reestablishing the topological relation and the resource use strategy pool according to the redetermined first physical usable area and the redetermined second physical usable areas.

For example, the originally acquired target resource is distributed in the physically available area A, B, C, D. If the target resource in the physical usable area a is found to be damaged currently, or the physical usable area a where the target resource is located is damaged, the newly acquired target resource is distributed in the physical usable area B, C, D.

In the application, when it is determined that the resource usage policy pool changes, the abnormal or broken physical available area in the resource usage policy pool may be deleted, or the abnormal or broken physical available area may be marked, so as to avoid accessing the broken or abnormal physical available area.

Fig. 2 is a schematic flowchart of a second cloud data access method in the present application, and as shown in fig. 2, the method includes:

step 201, acquiring the condition of an available area of service resources in a cloud server system through service monitoring;

here, the service resource may refer to a service component in the cloud server system, and the service monitoring may refer to a monitoring component in the cloud server system for monitoring a distribution condition of each service component in the cloud server system.

Specifically, a service component in the cloud server system may send a service distribution query instruction to a cloud management platform through service monitoring, so as to query first physical available area information corresponding to the service resource in the cloud server system; here, the service distribution query instruction usually carries service information; for example, the service information includes, but is not limited to, a server name, a server IP address, and a server domain name. When the cloud management platform receives a service distribution query instruction sent by the cloud server system, first physical available area information corresponding to the service information can be queried from a cloud database according to the service information carried in the service distribution query instruction, and the first physical available area information corresponding to the service information is sent to the service monitor. Here, the cloud management platform generally stores a correspondence between each service information and each physical usable area, and the first physical usable area information corresponding to the service information may be queried based on the correspondence. After receiving first physical available area information corresponding to the service information sent by the cloud management platform for the service resource, the service monitor sends the first physical available area information to the service resource, and the service resource can determine the distribution condition of the service resource in the cloud server system according to the first physical available area information.

Or, determining the distribution condition of the service resources by receiving the first notification message sent by the cloud management platform through service monitoring. Specifically, the cloud management platform may further send a first notification message for the service resource to the cloud server system according to a preset interval time, where the first notification message carries service information of the service resource and corresponding first physical available area information. For example, the service information of the service resource includes, but is not limited to, a server name, a server IP address, and a server domain name. After monitoring a first notification message sent by the cloud management platform for the service resource, the service monitor in the cloud server system sends the first notification message to the corresponding service resource according to the service information carried in the first notification message, and after receiving the first notification message, the service resource can determine the distribution condition of the service resource in the cloud server system based on the first physical available area information carried in the first notification message.

Step 202, acquiring the distribution condition of target resources to be used through service monitoring;

here, the cloud server system may send a target resource distribution query instruction to the cloud management platform at a preset time interval through service monitoring to query a plurality of second physical available areas corresponding to the target resource in the cloud server system; here, the target resource distribution query instruction carries target resource information. Here, the target resource information includes, but is not limited to, a domain name of the target resource, an IP address of the target resource. After receiving the target resource distribution query instruction sent by the service monitor, the cloud management platform may query corresponding physical available area information in the cloud database according to target resource information carried in the target resource distribution query instruction, and send a plurality of pieces of physical available area information queried for the target resource distribution query instruction to the cloud server system. Here, the cloud management platform stores a corresponding relationship between each resource information and each physical available area, and the physical available area corresponding to the target resource information can be queried based on the corresponding relationship; the service monitoring can send the second physical available area information to the service resource after monitoring the second physical available area information fed back by the cloud management platform based on the target resource information; the service resource can determine the distribution condition of the target resource in the cloud server system based on the plurality of second physical available area information.

In the application, the service monitor may further receive a second notification message sent by the cloud management platform to the cloud server system according to a preset interval time, where the second notification message carries target resource information of the target resource in the cloud server system and a plurality of corresponding second physical available area information. The service monitoring sends the second notification message to the corresponding service component according to the target resource information, and after the service component in the cloud server system receives the second notification message, the distribution condition of the target resource in the cloud server system can be determined based on the target resource information carried in the second notification message.

For example, the distribution status of the acquired target resource is: the target resources are distributed in the physically available area A, B, C, D.

Step 203, acquiring the available area condition of the target resource to be used through service monitoring;

here, the usable area status of the target resource represents whether the state of the physical usable area where the current target resource is located is normal or abnormal. Since environmental factors, regional factors, network factors, and the like may cause an abnormality or damage to a physical usable area in the physical usable area A, B, C, D where the target resource is distributed, in order to avoid a resource failure of the accessed physical usable area, only the physical usable area that is currently normal or not damaged may be obtained through service monitoring.

For example, the target resource is distributed in the physical usable region A, B, C, D, but if the physical usable region D is found to be damaged or abnormal, only the physical usable region A, B, C where the target resource is distributed is obtained. This may avoid access failures to the resources.

Step 204, establishing a corresponding resource use strategy pool;

here, first, a topological relation between the service resource and the target resource needs to be established according to the physical available area identifier, the distance information, and/or the idle state information between the service resource and the target resource, and then a resource usage policy pool representing the service resource and the target resource is generated based on the topological relation. And the resource usage policy pool is configured with resource weight information of each second physical available region of the target resource distribution; the resource weight information at least comprises a first weight factor representing the identification of each second physical available area, a second weight factor representing the distance between each second physical available area and the first physical available area, and a third weight factor representing the current use state of each second physical available area.

Since the network speed between different physically available areas is lower than the network speed inside the same physically available area, and there are cloud server systems in which access between different physically available areas needs to be charged, the first weighting factor in the resource weighting information has the highest weight, and the second weighting factor is the next highest.

Step 205, selecting and using the optimal resource according to the resource weight information configured in the resource use strategy pool;

here, since the network speed between the same physically available areas is fastest, and the network transmission is not charged. Therefore, based on the resource weight information configured in the resource usage policy pool, a second physical available region, which represents that the target resource and the service resource are located in the same physical available region, may be preferentially selected as the target physical available region, and the target resource of the target physical available region is determined as the optimal resource.

If the resource weight information of each second physical usable area configured in the resource usage policy pool represents that none of the plurality of second physical usable areas is the same as the first physical usable area, selecting the second physical usable area, which is the shortest distance from the first physical usable area, of the plurality of second physical usable areas as a target physical usable area; and determining the target resource of the target physical available area as the optimal resource. This is because the shorter the distance between different physically available areas, the higher the network speed and the lower the charge for network transmission.

If the resource weight information of each second physical usable area configured in the resource usage policy pool indicates that none of the second physical usable areas is the same as the first physical usable area, and the distance from the first physical usable area is not much, the second physical usable area currently in an idle state may be further selected as the target physical usable area. And determining the target resource of the target physical available area as the optimal resource. This is because the network speed in the idle state is higher than the network speed in the active state when the distances between different physically available areas are close.

Of course, in the present application, it is also preferable to select, as the target physical usable area, a second physical usable area that represents that the target resource and the service resource are located in the same physical usable area, and is the shortest from the first physical usable area among the plurality of second physical usable areas and is currently in an idle state. And determining the target resource of the target physical available area as the optimal resource. Thus, the network speed is higher during data access, and the network transmission fee is not charged.

Step 206, determine whether the current resource usage policy pool changes.

Here, if the service resource fails to access the target resource in the target physical usable area, it is determined that the current target physical usable area is abnormal or damaged, which indicates that the current resource usage policy pool has changed, and step 201 to step 205 are executed again.

Fig. 3 is a schematic flow chart diagram of a cloud data access method in the present application, as shown in fig. 3:

the system comprises a component 1.0, a component 1.1, a component 2.0 and a component 2.1, wherein two same resources which are backed up with each other are stored in the component 1.0 and the component 1.1. Two identical resources that back up each other are also stored in component 2.0 and component 2.1. And both component 1.0 and component 2.0 are distributed in a physically available area a in the cloud server system, and component 2.0 and component 1.1 are distributed in a physically available area B in the cloud server system. When the target resources that the component 1.0 and the component 1.1 want to access are distributed in the component 2.0 and the component 2.1, the target resources of the component 2.0 located in the same physical available area as the component 1.0 can be preferentially allocated to the component 1.0 and the target resources of the component 2.1 located in the same physical available area as the component 1.1 can be preferentially allocated to the component 1.1 through service monitoring. Since the network transmission speed is highest in the same physical available area and no network accommodation is generated, the target resource of the component 2.1 is allocated to the component 1.1, and the target resource of the component 2.0 is allocated to the component 1.0, so that the data flow speed can be increased, and no additional network cost is generated.

Fig. 6 is a schematic structural diagram of a cloud server system in the present application, and as shown in fig. 6, the system includes:

the service component 601, the service monitoring component 602, the resource component 603 and the cloud management platform 604, wherein the service component 601 sends a service distribution query instruction to the cloud management platform 604 through the service monitoring component 602 to query first physical available area information corresponding to the service component 601 in the cloud server system; wherein, the service distribution query instruction carries service information of the service component 601, such as a service domain name, an IP address, and the like; after receiving the service distribution query instruction, the cloud management platform 604 queries a cloud database based on the service information carried in the service distribution query instruction to obtain first physical available area information corresponding to the service component 601, sends the first physical available area information to the service monitoring component 602, sends the first physical available area information to the service component 601 by the service monitoring component 602, and determines the distribution condition of the service component 601 in the cloud server system according to the first physical available area information.

In this application, the service component 601 may further send a target resource distribution query instruction to the cloud management platform 604 through the service monitoring component 602, so as to query information of a plurality of second physical available areas corresponding to the resource component 603 in the cloud server system; the target resource distribution query instruction carries resource information of the resource component 603, such as a resource name, a domain name, an IP address, and the like; after receiving the target resource distribution query instruction, the cloud management platform 604 queries a cloud database based on resource information carried in the target resource distribution query instruction to obtain a plurality of pieces of second physical available area information corresponding to the resource component 603, sends the plurality of pieces of second physical available area information to the service monitoring component 602, and sends the plurality of pieces of second physical available area information to the service component 601 by the service monitoring component 602, where the service component 601 can determine the distribution condition of the target resource to be accessed in the cloud server system according to the plurality of pieces of second physical available area information.

In this application, since environmental factors, regional factors, network factors, and the like may cause an abnormality or damage to a certain physical usable area in the physical usable area A, B, C, D where the target resource is distributed, in order to avoid a failure of accessing the resource in the physical usable area, the service component 601 may obtain only the current normal or undamaged physical usable area information from the cloud management platform 604 through the service monitoring component 602.

For example, the target resource is distributed in the physical usable region A, B, C, D, but if the physical usable region D is found to be damaged or abnormal, only the physical usable region A, B, C where the target resource is distributed is obtained. This can avoid a situation where the service component 601 fails to access the target resource of the physically usable area D.

In this application, when the service component 601 obtains the physical available regions distributed in the cloud server system by the service component 601 and the resource component 603, the service component 601 may further establish a topological relationship between the service component 601 and the resource component 603 according to the physical available region identifier, the distance information, and/or the idle state information between the service component 601 and the resource component 603, and then generate a resource usage policy pool representing the service component 601 and the resource component 603 based on the topological relationship. And the resource usage policy pool is configured with resource weight information of each second physical available zone distributed by the resource component 603; the resource weight information at least comprises a first weight factor representing the identification of each second physical available area, a second weight factor representing the distance between each second physical available area and the first physical available area, and a third weight factor representing the current use state of each second physical available area.

Since the network speed between different physically available areas is lower than the network speed inside the same physically available area and the access between different physically available areas needs to be charged, the first weight factor is the highest in the weight information of the resource and the second weight factor is the next highest.

Here, please refer to the method description for specifically selecting the optimal resource to use according to the resource weight information configured in the resource usage policy pool, which is not described herein again.

If the service component 601 fails to access the resource component 603 in the target physical available region, it determines that the current target physical available region is abnormal or damaged, which indicates that the current resource usage policy pool changes, resends the target resource distribution query instruction to the service monitoring component 602, so as to obtain a plurality of second physical available regions corresponding to the resource component 603 in the cloud server system from the cloud management platform 604, and reestablish the topology relationship between the first physical available region and the plurality of second physical available regions and the resource usage policy pool. Therefore, the optimal resource can be accessed by the optimal resource access path at any time.
