First, popularize knowledge. Cloud computing can be divided into three types from the perspective of service methods: Public clouds that provide open computing and storage services to the public ", such as Baidu search and various email services; deployed in the firewall to provide a "private cloud" for a specific organization "; and the "hybrid
is server-side stability, and the other is the stability of the mobile phone side.Service-side stability, because the use of long-connection scheme, the cost and requirements of the server is very large, the push scheme for server development requirements are high, mass line thread attached server stability is very challenging.The general criteria for evaluation include:-Simultaneous on-line peak (typically evaluated for server stability in millions of concurrent connections)-Average message la
components based on these. According to some situations of cloud components, the best practice object is to start from a management system with a certain degree of universal interaction of table forms, and gradually include system applications with complex interactions, it also has some support for the response type.
