Detailed Description

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, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In order to ensure data security of tenants in a multi-tenant application scenario, an embodiment of the present application provides a communication system, and referring to fig. 1, a schematic structural diagram of the communication system provided in the embodiment of the present application is provided. The communication system shown in fig. 1 may include one or more clients 101, a centralized server 102, one or more client servers 103, and one or more virtual machines 104. The client 101 may operate in a terminal device, and the terminal device may include any one or more of a smart phone, a tablet computer, a notebook computer, a desktop computer, an intelligent vehicle, and an intelligent wearable device. The central server 102, the client server 103, and the virtual machine 104 may be independent physical servers, may also be a server cluster or a distributed system formed by a plurality of physical servers, and may also be cloud servers that provide basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, Network services, cloud communication, middleware services, domain name services, security services, Content Delivery Networks (CDNs), and big data and artificial intelligence platforms. The client 101, the central server 102, the client server 103, and the virtual machine 104 may be directly or indirectly connected in a wired or wireless communication manner, and the present application is not limited herein.

In one embodiment, the central server 102, the client server 103, and the virtual machine 104 collectively provide service support for the client 101, for example, if the client 101 is a client providing a simulation supercomputing function for a scientific research user, the central server 102, the client server 103, and the virtual machine 104 collectively provide simulation supercomputing service support for the client. Further, different users can log in the client 101 through their user accounts to use the corresponding functions provided by the client 101, and since the user accounts of different users are independent of each other, after different users log in the client 101 using their user accounts, it means that different users correspond to different clients 101.

In one embodiment, the central server 102 is a server that provides business services, such as may be a business server that provides emulated supercomputing services; the client server 103 is a server running with micro services, and is mainly used for forwarding data to schedule cloud resources for data processing, wherein the virtual machine 104 may be scheduled by the client server 103 as a cloud resource. Data interaction between the client 101 and the central server 102, and between the central server 102 and the client server 103 can be realized through protocols such as hypertext Transfer Protocol (HTTP), remote invocation Protocol (grpc), and the like.

In one embodiment, a tenant may perform a resource lease, or service lease as it were, to a service provider to use a corresponding service provided by the service provider. Specifically, a person in charge of the tenant may submit a requirement for resource lease through the client 101, and the client 101 may generate a resource lease request according to the resource lease requirement submitted by the person in charge of the tenant, and send the resource lease request to the central server 102; after receiving the resource lease request, the central server 102 performs a resource configuration operation according to the resource lease request, which may specifically include: allocating corresponding resources to the tenant's responsible person (that is, allocating corresponding client server and virtual machine to the tenant's responsible person, allocating one client server to one tenant, and allocating one or more virtual machines to one tenant), and storing the corresponding relationship between the tenant and the allocated resources in the database of the central server 102; after completing resource configuration, the central server 102 returns a prompt message of successful lease to the client 101, so as to prompt the responsible person of the tenant that the resource lease is successful. After the principal of the tenant leases the resource to the service provider, the user included in the tenant can also use the resource leased by the tenant.

Further, the client server 103 and the virtual machine 104 included in the communication system are both the client server 103 and the virtual machine 104 leased by the tenant. One tenant corresponds to one client server 103, different tenants correspond to different client servers 103, and one client server 103 only provides services for the tenant renting the client server 103, that is, one client server 103 only provides services for the user under the tenant renting the client server 103, and no other tenant provides services; one tenant corresponds to one or more virtual machines 104, i.e., the tenant can lease one or more virtual machines on demand, and one tenant can use only the guest server or virtual machine that it leases, but not the guest server or virtual machine that the remaining users lease.

Further, the client server 103 can only communicate with the virtual machine 104 in addition to the central server 102, that is, the client servers 103 rented by different tenants cannot communicate with each other, and the client server 103 rented by one tenant can only communicate with the virtual machine 104 rented by the tenant in the virtual machine 104, but cannot communicate with the virtual machines 104 rented by the other tenants in the virtual machine 104. The virtual machines 104 of different tenants cannot communicate with each other, and the virtual machine 104 of one tenant can only communicate with the client server 103 of the tenant in the client server 103, but cannot communicate with the client servers 103 of the other tenants in the client server 103. When the central server 102 performs resource configuration operation according to the resource lease request, communication restrictions can be set on the client server 103 leased by the tenant and the virtual machine 104 leased by the tenant.

For example, as shown in fig. 2, an interaction diagram of a communication system provided in the embodiment of the present application is shown. If tenant a comprises user a1, user a2 and user A3, which respectively correspond to client a1, client a2 and client A3, the client server leased by tenant a is client server a, and the virtual machines leased by tenant a are virtual machine a1, virtual machine a2 and virtual machine A3; tenant B comprises a user B1 and a user B2, which respectively correspond to a client B1 and a client B2, wherein the client server corresponding to tenant B is client server B, and the virtual machines corresponding to tenant B are virtual machine B1 and virtual machine B2; tenant C comprises user C1 and user C2, which respectively correspond to client C1 and client C2, the client server corresponding to tenant C is client server C, and the virtual machine corresponding to tenant C is virtual machine C1; the client server a can only communicate with the virtual machine a1, the virtual machine a2, and the virtual machine A3 of the virtual machines, and the virtual machine a1, the virtual machine a2, and the virtual machine A3 can only communicate with the client server a of the client servers; the communication method between the client server B and the virtual machine B1 and the virtual machine B2 is similar to the communication method between the client server a and the virtual machine a1, the virtual machine a2 and the virtual machine A3, and the communication method between the client server C and the virtual machine C1 is similar to the communication method between the client server a and the virtual machine a1, the virtual machine a2 and the virtual machine A3, and thus, the description thereof is omitted.

In one embodiment, a target user can input a task requirement through a corresponding target client, and the target user can be any user included in a tenant leasing a client server and a virtual machine; the target client can generate a task request for requesting service according to the task requirement input by the target user and send the task request to the central server; after receiving the task request, the central server sends the task request to a target client server corresponding to the target client (the target client server corresponding to the target client is a client server leased by a target tenant to which the target user belongs); after receiving the task request, the target client server sends the task request to a target virtual machine corresponding to the target client (the target virtual machine corresponding to the target client is a virtual machine leased by a target tenant to which the target user belongs); and after receiving the task request, the target virtual machine processes the task request to obtain a processing result of the task request.

Based on the communication system, the embodiment of the present application provides a service processing method, where the service processing method may be applied in a multi-tenant application scenario, and the service processing method may be applied in a central server, where a communication system to which the central server belongs may include one or more clients, a client server corresponding to each client in the one or more clients, a virtual machine corresponding to each client, and the central server. The communication system to which the central server belongs may be the communication system shown in fig. 1 or fig. 2. The virtual machine corresponding to one client is a virtual machine leased by the tenant to which the user corresponding to the client belongs. Referring to fig. 3, a schematic flow chart of a service processing method provided in the embodiment of the present application is shown. The service processing method shown in fig. 3 may include the steps of:

s301, receiving a task request sent by a target client in one or more clients.

The target client is any one of one or more clients.

In one embodiment, the task request is used for requesting a service, and the task request is generated according to a task requirement input in a target client by a target user corresponding to the target client. For example, if the target client is a client providing a simulation supercomputing function, when the target user is performing experimental simulation, the target user may select a simulation tool, input simulation parameters, set an output format of a simulation result, and the like in the target client, and the target client generates a task request for requesting simulation according to task requirements of the simulation tool, the input simulation parameters, the set output format of the simulation result, and the like determined by the target user.

Further, the task request may carry a client identifier of the target client, where the client identifier of the target client is used to identify a target user corresponding to the target client, and may be a user account of the target user; after receiving the task request sent by the target client, the central server may send the task request to the target client server corresponding to the target client according to the client identifier of the target client carried in the task request, that is, step S302 is executed in turn.

S302, the task request is sent to a target client server corresponding to the target client, so that the target client server schedules a target virtual machine corresponding to the target client to process the task request according to the identity information of the target client, and a processing result of the task request is obtained.

The identity information of the target client may be used to schedule resources that can be used by a target user corresponding to the target client, that is, to schedule resources leased by a target tenant to which the target user belongs, that is, to schedule the target client server and the target virtual machine so as to use corresponding services provided by the target client server and the target virtual machine. The identity information of the target client may be security credential information of a target tenant to which a target user corresponding to the target client belongs, where the security credential information may include service tenant information (secret ID) and Key information (secret Key), and the service tenant information is used to identify a tenant leasing the client server and the virtual machine; one tenant corresponds to one set of security credential information, that is, one tenant corresponds to one set of secretID and secretKey, and all users under one tenant share one set of security credential information, that is, the identity information of the clients corresponding to all users under one tenant is the same and is the security credential information of the tenant. The security credential information of the tenant is stored in a memory of a client server leased by the tenant, the central server does not store the security credential information of the tenant, and since the client server leased by the tenant can only be used by the tenant and is isolated from the client servers leased by other tenants, the central server sends the received task request to the target client server, and then the target client server calls a target virtual machine corresponding to the target client to process the task request according to the identity information of the target client (namely, the security credential information of the target tenant to which the target user corresponding to the target client belongs), so that the security of the security credential information of the tenant can be protected.

In a specific implementation, the sending, by the central server, the task request to the target client server corresponding to the target client may include: searching a server identifier corresponding to the client identifier of the target client as a target server identifier according to a pre-established corresponding relationship between the client identifier and the server identifier of the client server; and sending the task request to a target client server corresponding to the target server identifier. After the tenant leases the client server and the virtual machine, the central server can acquire a client identifier of a client corresponding to a user under the tenant; and constructing a corresponding relation between the client identification and the server identification of the client server leased by the tenant based on the acquired client identification. The server identifier of the client server is used to uniquely identify the client server, and may be, for example, a host name of the client server, an IP address of the client server, and the like.

In one embodiment, when performing a resource configuration operation according to the resource lease request, the central server may store a correspondence between a tenant and a resource leased by the tenant, for example, may store a correspondence between a tenant identifier of the tenant and a server identifier of a client server leased by the tenant, where the tenant identifier is used to uniquely identify the tenant, and may be, for example, a name of the tenant. Then, the sending, by the central server, the task request to the target client server corresponding to the target client may include: determining a tenant identification of a target tenant to which a target user corresponding to a target client belongs according to the client identification of the target client, and taking the tenant identification as the target tenant identification; and sending the task request to a target client server corresponding to the target tenant identification.

In an embodiment, the communication system to which the central server belongs may further include cloud storages corresponding to the clients, as shown in fig. 4a, which is an interaction schematic diagram of another communication system provided in the embodiment of the present application, where the cloud storage corresponding to the client is a cloud storage leased by a tenant to which a user corresponding to the client belongs, and the cloud storage leased by one tenant communicates with a virtual machine leased by the tenant, so as to store a processing result produced by the virtual machine. That is to say, when the central server sends the task request to the target client server corresponding to the target client, so that the target client server schedules the target virtual machine corresponding to the target client to process the task request according to the identity information of the target client, and obtains a processing result of the task request, the target virtual machine may send the processing result to the target cloud storage corresponding to the target client; the target cloud storage stores the processing result to obtain a cloud storage address of the processing result, and sends the cloud storage address of the processing result to the target virtual machine; after receiving the cloud storage address of the processing result, the target virtual machine sends the cloud storage address of the processing result to the target client server; after receiving the cloud storage address of the processing result, the target client server sends the cloud storage address of the processing result to the central server; the central server can acquire the processing result from the target cloud storage according to the cloud storage address of the processing result and send the processing result to the target client.

That is to say, the central server sends the task request to a target client server corresponding to the target client, so that the target client server schedules a target virtual machine corresponding to the target client to process the task request according to the identity information of the target client, and after a processing result of the task request is obtained, a cloud storage address of the processing result sent by the target client server can be received, wherein the cloud storage address of the processing result is sent to the target client server by the target virtual machine, the cloud storage address of the processing result is obtained by the target virtual machine after the processing result is stored in a target cloud storage corresponding to the target client, and the cloud storage address of the processing result is a storage address of the processing result in the target cloud storage; and acquiring a processing result from the target cloud storage according to the cloud storage address of the processing result, and sending the processing result to the target client. After the target virtual machine obtains a processing result, the processing result is stored in a target cloud storage, and a cloud storage address of the processing result returned by the target cloud storage is sent to a central server through a target client server, so that the central server stores the cloud storage address of the processing result; the central server does not store the processing result, only stores the cloud storage address of the processing result, and calls the processing result based on the cloud storage address of the processing result when the processing result needs to be called, so that the data security of the tenant can be ensured.

Optionally, if the central server is a service server capable of providing a simulation supercomputing service, the client server is a server providing a Cloud container service (TKE), the TKE may run a micro service, the Virtual Machine is a Cloud Virtual Machine (CVM), and the Cloud Storage is a Cloud Storage providing an Object Cloud Storage service (COS), the interaction diagram of the communication system shown in fig. 4a may also be shown in fig. 4b, and includes a service front end, a service back end, the Cloud container service TKE, the Cloud Virtual Machine CVM, and the Object Cloud Storage service COS. The service front end directly interacts with the user through the client. Alternatively, when only one target user makes a service call, the interaction diagram of the communication system can be as shown in fig. 4 c.

In one embodiment, after the target virtual machine sends the cloud storage address of the processing result to the target client server, the target virtual machine is deallocated, so that other users under the tenant can call the target virtual machine after the deallocation. Fig. 5a is a schematic diagram of an idle time of a communication system according to an embodiment of the present application, where the idle time of the communication system is when no task request is processed in the communication system and all virtual machines in the communication system are unoccupied. Optionally, if the central server is a service server capable of providing a simulation supercomputing service, the client server is a server providing a Cloud container service (TKE), the TKE may run a micro service, the Virtual Machine is a Cloud Virtual Machine (CVM), and the Cloud Storage is a Cloud Storage providing a Cloud Object Storage service (COS), then the schematic diagram of the communication system shown in fig. 5a when it is idle may also be shown in fig. 5b, and includes a service front end, a service back end, and a Cloud container service TKE. The service front end directly interacts with the user through the client.

In one implementation, the target client server may schedule the target virtual machine corresponding to the target client according to the identity information of the target client through the batch computing interface, or alternatively, may be implemented through any other forwarding interface capable of sending the task request to the target virtual machine. When a plurality of users input respective task requirements in respective clients at the same time to request for service (namely, a plurality of target users and a plurality of target clients exist at the same time), the central server can respectively send the task requests corresponding to the target clients in the plurality of target clients to the target client servers corresponding to the target clients, so that the target client servers corresponding to the target clients schedule the target virtual machines corresponding to the target clients according to the identity information of the target clients, and process the task requests corresponding to the target clients to obtain the processing results of the task requests corresponding to the target clients; and the target client server corresponding to each target client schedules the target virtual machine corresponding to each target client according to the identity information of each target client through a batch computing interface. For example, if tenant a includes user a1, user a2, and user A3, which correspond to client a1, client a2, and client A3, respectively, the client server leased by tenant a is client server a, and the virtual machines leased by tenant a are virtual machine a1, virtual machine a2, and virtual machine A3; tenant B comprises a user B1 and a user B2, which respectively correspond to a client B1 and a client B2, wherein the client server corresponding to tenant B is client server B, and the virtual machines corresponding to tenant B are virtual machine B1 and virtual machine B2; tenant C comprises user C1 and user C2, which respectively correspond to client C1 and client C2, the client server corresponding to tenant C is client server C, and the virtual machine corresponding to tenant C is virtual machine C1; if the target user is user a1, user b1 and user c1, the target client server a may invoke one or more of the target virtual machine a1, the target virtual machine a2 and the target virtual machine A3 through the batch computing interface to process the task request correspondingly generated by the user a 1; the target client server B can call one or more of the target virtual machine B1 and the target virtual machine B2 through the batch computation interface to process the task request correspondingly generated by the user B1; the target client server C may call the target virtual machine C1 through the batch computation interface to process the task request generated by the user C1.

In an embodiment, as shown in fig. 6, for an interaction schematic diagram provided by the embodiment of the present application when a target user requests a service, the target user inputs a task requirement in a target client corresponding to the target user, and the target client may generate a task request for requesting the service according to the task requirement input by the target user and send the task request to a central server; after receiving the task request, the central server sends the task request to a target client server corresponding to a target client; after receiving the task request, the target client server can schedule a target virtual machine corresponding to the target client and send the task request to the target virtual machine so that the target virtual machine processes the task request to obtain a processing result of the task request; after the target virtual machine obtains the processing result of the task request, the processing result can be sent to a target cloud storage corresponding to the target client; the target cloud storage stores the processing result to obtain a cloud storage address of the processing result, and sends the cloud storage address of the processing result to the target virtual machine; after receiving the cloud storage address of the processing result, the target virtual machine sends the cloud storage address of the processing result to the target client server; the target client server sends the cloud storage address of the processing result to the central server; and the central server acquires the processing result from the target cloud storage according to the cloud storage address of the processing result and sends the processing result to the target client so as to display the processing result through the client.

Based on the communication system embodiment and the service processing method embodiment, the present application embodiment provides another service processing method, where the service processing method may be applied in a multi-tenant application scenario, and the service processing method may be applied in a client server, where a communication system to which the client server belongs includes one or more clients, a client server corresponding to each client in the one or more clients, a virtual machine corresponding to each client, and a central server, where the client server is a target client server corresponding to a target client in the one or more clients, and the target client is any client in the one or more clients. The communication system to which the client server belongs is the same as the communication system to which the service processing method belongs, one user corresponds to one client, the client server to which one client corresponds is a client server leased by a tenant to which the user corresponding to the one client belongs, and the virtual machine to which one client corresponds is a virtual machine leased by the tenant to which the user corresponding to the one client belongs. Referring to fig. 7, a schematic flow chart of another service processing method provided in the embodiment of the present application is shown. The service processing method shown in fig. 7 may include the steps of:

s701, receiving a task request sent by a central server.

The task request is sent to the central server by the target client, and the task request is generated according to the task requirement input in the target client by the target user corresponding to the target client.

S702, the target virtual machine corresponding to the target client is dispatched to process the task request according to the identity information of the target client, and a processing result of the task request is obtained.

The target client server integrates an interface for calling cloud resources required by service logic, namely, integrates a calling interface of a virtual machine leased by a target tenant, and can call the virtual machine through the calling interface of the virtual machine.

In specific implementation, a target client server acquires identity information of a target client from a memory of the target client server; and sending the task request and the identity information of the target client to a target virtual machine corresponding to the target client so that the target virtual machine authenticates the target client according to the identity information of the target client, and if the target virtual machine passes the authentication of the target client, processing the task request to obtain a processing result of the task request.
