Description

A general cloud server testing method

technical field

The invention relates to cloud testing technology, in particular to a general cloud server testing method.

Background technique

Cloud server is an important part of cloud computing in infrastructure applications. It is located at the bottom of the cloud computing industry chain pyramid, and its products are derived from cloud computing platforms. The platform integrates three core elements of Internet applications: computing, storage, and network, and provides public Internet infrastructure services for users. The cloud server is a group of cluster hosts that virtualize multiple parts similar to independent hosts. Each host in the cluster has a mirror image of the cloud server, which greatly improves the security and stability of the virtual host, unless all hosts in the cluster If all problems occur, the cloud server will be inaccessible.

At present, there is a test method model for the cloud platform. In this model, the environment and construction layout required for cloud platform testing are described. Many cloud vendors have also given their own set of cloud server test methods. However, for cloud users, A set of standard cloud server testing methods is particularly important.
