: application objects, database records, algorithms, and so on. Each resource uses a URI (Universal Resource Identifier) to get a unique address. All resources share a unified interface to transfer state between the client and the server. Standard HTTP methods are used, such as GET, PUT, POST, and DELETE. Hypermedia is the engine of application state, and resources are interconnected through hyperlinks.Another important REST principle is a hierarchical system , which means that a component canno

memory usage is smooth. So, this value is the performance of the system.Four, find the limit value of the system. For example: In the case of a success rate of 100% (regardless of the length of response time), the system can adhere to 10 minutes of throughput.Five, do burst Test. The throughput performed in the second step is executed for 5 minutes, then the limit value obtained in the fourth step is executed for 1 minutes, then the throughput of the second step is executed for 5 minutes, then
