Automatic evaluation and optimization method of cloud resource utilization rate based on pressure test

The invention relates to an automatic evaluation and optimization method for a cloud resource utilization rate based on a pressure test, and belongs to the technical field of cloud resource allocation. The method comprises the following steps: describing deployed cloud services by using a pressure test description language, wherein the description mainly comprises cloud resource description, typical service scene interface description, performance requirements and the like; automatically generating a pressure test code according to the description language and initiating a pressure test; monitoring the performance of each component by using an interface provided by the cloud platform in a pressure test process, and obtaining monitoring indexes including a CPU utilization rate and the like; after the pressure test is finished, comprehensively analyzing the collected monitoring data and test data, and giving a description whether cloud resource configuration is reasonable or not according to a cloud resource ut
