[0002] Considering factors such as reliability, cost, and functionality, business platforms typically deploy different applications in different cloud environments. These cloud environments can be various types, including public clouds, private clouds, container clouds, and hybrid clouds. When problems arise during application operation, it may be necessary to access the terminal within the application's cloud environment to locate and analyze the problem. This terminal can be located in environments such as virtual machines, physical machines, Docker containers, or Kubernetes pods. Due to the differences between different cloud environments, the access technologies for virtualized environments such as hosts, containers, and pods also differ. Currently, cloud environment vendors typically provide an access interface tool tailored to the specific cloud environment they offer, using SSH and WebSocket technologies.

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0057] To address the inconvenience caused to business operation and maintenance analysis due to the lack of a unified access method for different cloud environments, embodiments of this application provide a resource access system, such as... Figure 1 As shown, the resource access system includes a connection management module and a host agent module.

[0058] The connection management module and the host agent module can communicate with each other.

[0059] In one possible implementation, the connection management module includes a gateway, which may be, for example, an API gateway.

[0060] In one possible implementation, the host agent module can be set on the host or on other devices that can communicate with the host.

[0061] Optionally, the connection management module receives resource access requests sent by the front end and routes the resource access requests to the host proxy module, that is, forwards the resource access requests to the corresponding host proxy module. The resource access request includes a host identifier and / or an application identifier, and the resource access request is used to access resources in any cloud environment.

[0062] Subsequently, the host proxy module determines the target access method, i.e. the access method of the cloud environment where the target resource is located, based on the host identifier and / or application identifier in the resource access request, and uses the target access method to access the target resource.

[0063] Depending on the target resource to be accessed, the resource access request contains different content.

[0064] In one possible implementation, if the target resource to be accessed is a host resource, such as host configuration information, then the resource access request includes the host identifier; if the target resource to be accessed is an application resource, such as application configuration information, then the resource access request includes both the host identifier and the application identifier.

[0065] In other words, based on the content included in the resource access request, it can be determined whether the resource to be accessed, i.e. the target resource, is the host itself or an application set up on the host.

[0066] In one possible implementation, after receiving a resource access request, the connection management module queries the database based on the host identifier in the request to determine the host address corresponding to the host identifier as the address of the target host. Subsequently, based on the address of the target host, the connection management module establishes a connection with the host proxy module corresponding to the target host and routes the resource access request to the host proxy module corresponding to the target host.

[0067] The aforementioned database is used to store the correspondence between host addresses and host identifiers. The target host is the host where the target resource is located.

[0068] In one possible implementation, the host proxy module corresponding to the target host is either the host proxy module on the target host or the host proxy module set on other devices that can communicate with the target host.

[0069] In this way, the connection management module can establish a connection with any host where the resource to be accessed is located through the corresponding host proxy module, which facilitates providing a unified interface for accessing the resource.

[0070] In one possible implementation, during the application deployment process on the business platform, a database is established to store the mapping between host addresses and host identifiers. A mapping exists between host addresses and host identifiers; the host address corresponding to a host identifier is the address of the host represented by that host identifier.

[0071] The content of the resource management request received by the connection management module from the front end will differ depending on the target resource to be accessed.

[0072] In another possible implementation, if the target resource to be accessed is a host resource, the resource access request includes the host identifier; if the target resource to be accessed is an application resource, the resource access request includes both the host identifier and the application identifier.

[0073] At this point, based on the content included in the resource access request, it can be determined whether the resource to be accessed, i.e., the target resource, is the host itself or an application set up on the host. If the resource access request includes a host identifier, the target resource can be determined to be the target host corresponding to that host identifier; if the resource access request includes an application identifier, the target resource is the target application corresponding to that application identifier.

[0074] Similarly, in this case, the aforementioned database is used to store the mapping between host addresses, host identifiers, and application identifiers. Specifically, there is a mapping between host identifiers and application identifiers; the host identifier corresponding to an application identifier is the identifier of the host on which the application represented by that application identifier is deployed. Similarly, there is a mapping between host addresses and host identifiers; the host address corresponding to a host identifier is the address of the host represented by that host identifier.

[0075] At this point, the connection management module can query the database based on the application identifier in the resource access request, directly determine the host address corresponding to the application identifier as the address of the target host, and then establish a connection with the host proxy module corresponding to the target host based on this address, and route the resource access request to the host proxy module corresponding to the target host.

[0076] Optionally, if the resource access request includes a host identifier, the connection management module routes the resource management request to the corresponding host proxy module. The host proxy module can then determine the target resource (i.e., the target host) based on the host identifier in the resource access request. Subsequently, the host proxy module determines the access method of the cloud environment where the target host resides as the target access method. At this point, the target host is the host corresponding to the host identifier in the resource access request.

[0077] In this way, the front end does not need to distinguish between cloud environments. The host proxy module can achieve unified access to the target host located in any cloud environment, thereby realizing a friendly interaction between the front end and the user and facilitating operation.

[0078] Optionally, if the resource access request includes a host identifier and an application identifier, the connection management module routes the resource management request to the corresponding host proxy module based on the host identifier. The host proxy module can then determine the target resource (i.e., the application) to be accessed based on the application identifier in the resource access request. The target application is the application corresponding to the application identifier in the resource access request. Subsequently, the host proxy module determines the access method of the cloud environment where the target application resides as the target access method.

[0079] In one possible implementation, the host proxy module determines the host on which the target application is deployed by querying resource tags. Generally, the host on which the target application is deployed is the host corresponding to the application identifier of the target application, i.e., the target host.

[0080] In one possible implementation, when the target resource is a target application, the target access method is used to access the target application based on whether the target application is directly deployed on the target host. That is, the appropriate target access method is used based on whether the target application is deployed directly on the physical machine of the target host or on a virtual machine of the target host.

[0081] If the target application is deployed directly on the physical machine of the target host, then the target access method is used to directly access the target application deployed on the physical machine of the target host.

[0082] Specifically, the host proxy module determines that the target application is directly deployed on the physical machine of the target host by querying resource tags. Then, it uses the target access method to establish a connection with the target host and accesses the target application directly deployed on the target host based on the connection.

[0083] Correspondingly, if the target application is not directly deployed on the physical machine of the target host, but rather on a virtual machine of the target host, then the identifier of the target virtual machine is determined, and based on this identifier, the target application deployed on the target virtual machine is accessed using the target access method. The target virtual machine is the virtual machine on the target host used to deploy the target application.

[0084] Specifically, the host proxy module determines the target application is deployed on the virtual machine of the target host, i.e., the target virtual machine, by querying the resource tags. Then, based on the identifier of the target virtual machine, it establishes a connection with the target virtual machine using the target access method, and accesses the target application deployed on the target virtual machine based on the connection.

[0085] Each application is assigned a corresponding resource tag during deployment. The content of this resource tag varies depending on the deployment scenario. For applications deployed directly on the host machine, the resource tag typically includes the application identifier and the host identifier. For applications deployed on a virtual machine on the host machine, the resource tag typically includes the application identifier, the host identifier, and the virtual machine identifier. Optionally, for any application, the resource tag may also include information such as the application type.

[0086] Understandably, the target access method will differ depending on the target resource to be accessed. After determining the target resource, the host proxy module can determine the target access method used to access that resource.

[0087] In existing technologies, different cloud environments may have different authentication requirements for accessing their resources, meaning the authentication methods for resource access requests are inconsistent, causing inconsistencies in accessing resources across different cloud environments. Optionally, in the resource access system provided in this application, after receiving a resource access request from the front end, the host proxy module authenticates the received resource access request before routing it to the host proxy module. At this time, the resource access request also includes authentication information. After receiving the resource access request, the connection management module authenticates the resource access request based on the authentication information in the request, obtaining an authentication result. If the authentication result is successful, access to the target resource is allowed, and the resource access request is routed to the host proxy module. If the authentication result is unsuccessful, access to the target resource is denied, for example, the resource access request is discarded, and it is not routed to the host proxy module.

[0088] It should be noted that, through the above resource access system, the front end does not need to directly access different cloud environments through different access methods. Instead, the connection management module and the host proxy module provide a unified interface for the front end. The front end only needs to send the resource access request to the connection management module, and it can access resources in different cloud environments through the unified interface, namely the host proxy module connected to the connection management module, thereby providing the front end with a unified access method in different cloud environments.

[0089] For example, taking the need to access application resources as an example, the resource access process can be as follows: Figure 2 As shown, the frontend connects to the API gateway in the connection management module via WebSocket. After receiving the corresponding instruction, the frontend sends the resource access request to the API gateway through this connection. Subsequently, the API gateway performs connection permission authentication based on the received resource access request and obtains the authentication result. If the authentication result is successful, based on the service registration mechanism, it queries the database for the corresponding host address and routes the resource access request to the host proxy module of the corresponding host based on the host address. The host proxy module establishes a connection between the host and the connection management module, and determines the appropriate access method based on the resource access request. The host proxy module deploys access tools for various cloud environments, such as access tools for pod cloud environments, docker cloud environments, and VB cloud environments. Subsequently, based on the resource tag, the host proxy module determines the cloud environment corresponding to the application to be accessed and selects the appropriate access tool to access the application deployed in different cloud environments, such as application instances deployed in shell, application instances deployed in dockerd, and application instances deployed in Kubernetes.

[0090] Each application instance is assigned a corresponding resource tag during deployment. This resource tag includes information such as application instance identifier, application instance type, and host identifier.

[0091] Generally, a host proxy module is deployed on the host resources where the application instance is located. This host proxy module is used to manage and forward connections to the terminal of the application instance (i.e. the terminal where the application instance is deployed, such as a host, virtual machine, container, etc.). It can shield the connection differences between the front end and various cloud environments, so that the front end does not need to distinguish between the differences between cloud environments and can directly access resources in various cloud environments.

[0092] In one possible implementation, the host proxy module will register all host proxy modules based on resource tags through a service registration mechanism.

[0093] It should be noted that through the middleware mechanism of the API gateway, the authentication mechanism provided by the API gateway can be used to achieve a secure connection, that is, a secure connection between the front end and the host proxy module or the host where the host proxy module is located. At the same time, it can shield the authentication differences when accessing various cloud environments.

[0094] For example, the page initiates a connection request to a resource terminal, carrying a host identifier and / or application identifier. Upon passing through the API gateway, user authentication is performed, and the page is routed to the corresponding host proxy module based on the host identifier and / or application identifier. Subsequently, the host proxy module, based on the current environment, employs the appropriate resource access technology, finding the corresponding host based on the host identifier, and the corresponding application based on the application identifier, or both, to establish a connection with the terminal where the application is deployed. This achieves a unified approach where the host proxy module automatically adjusts the access method according to the environment, providing a user-friendly and convenient interface.

[0095] In this application, a unified resource access method can be provided in a multi-cloud environment and with multiple deployment methods by using tagging technology in combination with API gateway, proxy technology, WebSocket and other technologies. This provides terminal access methods for personalized applications of business platforms, shields the resource access verification of cloud vendors, and provides a unified security authentication method according to business needs.

[0096] To address the inconvenience caused to business operation and maintenance analysis due to the lack of a unified access method for different cloud environments, this application provides a resource access method. This method is applied to the connection management module of the above-mentioned resource access system, such as an API gateway.

[0097] like Figure 3 As shown, the resource access method includes steps 301-302:

[0098] 301. Receive access request.

[0099] The resource access request includes a host identifier and / or an application identifier, and is used to access resources located in any cloud environment.

[0100] 302. Route resource access requests to the host proxy module.

[0101] This allows the host proxy module to determine the target access method based on the host identifier and / or application identifier in the resource access request, and then use that target access method to access the target resource.

[0102] The target access method refers to the access method of the cloud environment where the target resource is located.
