Description

Technical Field

[0001] The present invention relates to the field of desktop cloud, and specifically provides a method and device for realizing high availability of desktop cloud applications. Background Art

[0002] In the prior art, the implementation scheme of cloud applications mainly relies on the client to connect to the backend application server through the rdp protocol. This method not only has restrictions on the client operating system, but also has a single point of failure. When the backend server crashes, it will seriously affect the use of all users. The operation is complex, and maintenance personnel need to maintain multiple servers, with a large workload and unable to manage uniformly.

[0003] With the full application and promotion of the information technology innovation industry, some software adaptation problems have gradually emerged. Most software has poor compatibility with domestic products and cannot run on domestic Kylin, UOS and other systems. In order to improve the user experience in the information technology innovation environment, be compatible with domestic systems, and at the same time improve the service disaster tolerance ability, the high availability requirement of desktop cloud applications has emerged, mainly used to solve the problems of information technology innovation adaptation and compatibility, low utilization rate of hardware resources of ordinary cloud products, and inability to ensure user data security.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0007] A method for realizing high availability of desktop cloud applications has the following steps:

[0009] S2. The cloud application server gateway sends heartbeat detection to the backend regularly to judge whether the status of the backend server is normal, and ensure that the connection of the client can be allocated to a machine that can provide services normally;

[0010] S3. After the cloud application server has an exception, the gateway service sets the abnormal node as faulty;

[0011] S4. An integrated scheduling component is integrated in the cloud application gateway;

[0012] S5. When the client connects to the cloud application, it first sends a connection establishment request to the gateway management service;

[0013] After the client receives the gateway information, it initiates a connection to the application server and obtains the protocol flow data of the cloud application through this server.

[0014] Further, in step S1, the administrator sets the gateway service information including the gateway node IP, MAC, server type, and domain account.

[0015] Further, the administrator logs in to the management platform, sets the cloud application gateway cluster IP address and the administrator user password, specifies the domain information of the cloud application, installs the cloud application plugin in each backend cloud application server to report application information and connection information to the gateway server, and it will take effect after saving.

[0016] Further, in step S2, the cloud computer gateway health check is implemented by initiating a heartbeat check to the backend server. When the health check detects an abnormality in the backend application server, it will no longer forward traffic to the abnormal backend server until the health check detects that the backend server returns to normal, and then it will continue to forward traffic to the said server.

[0017] Further, in step S3, for the health check of the backend server, if the heartbeat packet of the backend application server is not received within a continuous period, the gateway service will automatically set the abnormal application server node to maintenance and report an alarm, and the client requests will no longer be distributed to the node.

[0018] Further, in step S4, when the client connects, it first requests the gateway service, and the gateway service distributes the request to the backend cloud application server cluster according to the client request type.

[0019] Further, in step S5, the gateway management service selects the specified application server according to the status of each server in the current gateway cluster through the load balancing algorithm and feeds back the connection information to the client.

[0020] The load balancing algorithm includes round-robin scheduling algorithm, weighted round-robin scheduling algorithm, random balancing algorithm, weighted random balancing algorithm, least-connection scheduling algorithm, weighted least-connection scheduling algorithm, destination-hash scheduling algorithm, or source-hash scheduling algorithm.

[0021] Further, in step S6, after the application gateway service allocates the gateway address, it is simultaneously sent to the client and the internal protocol end of the cloud application. The client and the protocol end will simultaneously initiate a connection establishment request to the gateway to open the protocol transmission network channel.

[0022] A device for realizing high availability of desktop cloud cloud applications includes: at least one memory and at least one processor.

[0023] The at least one memory is used to store machine-readable programs.

[0024] The at least one processor is used to call the machine-readable program to execute a method for implementing high availability of desktop cloud applications.

[0026] The present invention realizes the high availability of desktop cloud applications. Without affecting user use, the cluster scale can be dynamically and hot-adjusted according to indicators such as business pressure and user access conditions, solving the problems of user use lag, disconnection caused by excessive gateway pressure due to changes in business access volume, or business interruption caused by server downtime.
