Application cluster self-adaptive elastic configuration method

Abstract

The invention discloses an application cluster self-adaptive elastic configuration method. The configuration method is based on a PaaS platform and an ASP platform. The PaaS platform is a server, andthe ASP platform is a client. The method comprises the following steps: calculating an application topological structure by analyzing an application deployment packet; dividing the application into aplurality of application modules; the server monitoring whether an application module of a long-term leased virtual machine in the virtual machine cluster and an application module of an on-demand paid virtual machine resource are lower than or higher than a given threshold value or not; dispatching the virtual machine amount application modules for corresponding distribution migration again before migration, and distributing requests to each virtual machine cluster for distributed processing according to a redispatching scheme; completing configuration. According to the application cluster self-adaption elastic configuration method and the server, the cluster position where the virtual machine is located can be automatically adjusted, the utilization rate of the virtual machine rented fora long time is increased, the utilization rate of the virtual machine paid according to needs is reduced, and the purpose of reducing the operation cost is achieved.

Description

technical field [0001] The invention relates to an adaptive flexible configuration method of an application cluster, which belongs to the field of cloud computing information technology. Background technique [0002] Cloud computing is an information technology service model, which realizes quick and easy access to configurable virtual resource sharing pools (such as networks, servers, storage, applications, and services) anytime, anywhere, making the configuration and management of resources be completed quickly and efficiently. The three standard service models of cloud computing are: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). [0003] PaaS provides the customized middleware platform as a service to users. Users only need to focus on application deployment and management. The essence of PaaS is to serve Internet resources into programmable interfaces and provide third-party developers with commercially valuable ...

Problems solved by technology

Therefore, how to reasonably set the intensity of scheduling tasks for virtual machines of different lease types is of great significance for reducing operating costs, but so far there is no universal strategy that can adjust the lease type of virtual machines in real time according to the status of virtual machines
