Cloud server asynchronous creation method based on Rabbit MQ

Abstract

The invention discloses a cloud server asynchronous creation method based on Rabbit MQ, and relates to the technical field of distributed application systems. An order processing application and a resource creation application are established for creation of a cloud server. The order processing application and the resource creation application independently process respective services; communication is carried out through a Rabbit MQ message to achieve creation of cloud servers; compared with the prior art, according to the invention, coupling between two applications of order processing and resource creation is reduced; the two applications of order processing and resource creation are promoted not to depend on each other, so that two independent applications are formed; a distributed design architecture is met, order processing and resource creation do not need to perform excessive processing on exception of another application, the complexity of a program is reduced, the order processing and resource creation applications are restarted respectively, messages in Rabbit MQ can be read again for subsequent processing, and the stability of the system is also improved.

Description

technical field [0001] The invention discloses an asynchronous creation method of a cloud server based on Rabbit MQ, and relates to the technical field of distributed application systems. Background technique [0002] Cloud server products are the core and basic products of cloud services, and the implementation of cloud server creation varies from vendor to vendor. The creation of a cloud server is basically divided into two steps: order processing and resource creation. At present, the user initiates an order to create a cloud server. After the order is processed, an interface call to create a cloud server resource is initiated. After the cloud server interface call receives the creation message, it returns a notification that the resource is created and performs the creation operation. The creation is complete After that, the user is notified that the resource is created successfully. The above process has the following problems: [0003] Order processing and resource ...

AI Technical Summary

Problems solved by technology

[0003] Order processing and resource creation applications are highly coupled, which does not conform to the design principles of distributed applications. If the deployment of an application is changed, another application must also be changed and configured synchronously. Subsequent upgrades and maintenance work are cumbersome, and because applications are tightly coupled , if one application is restarted or fails, it is easy to cause problems in the access of another application, data inconsistency, some processing needs to be rolled back, etc., which greatly reduces the stability of the entire system;

[0004] And because of the interaction between the order processing and resource creation applications, the user's access information needs to be transferred between the two systems before responding, which increases the access time and reduces the user experience.
