A dynamic deployment method of micro service oriented to SLA
In order to solve the problem of frequent dynamic deployment of micro service in cloud computing environment under different load conditions, a dynamic deployment method of micro service oriented to SLA is proposed. A dynamic description model of micro-service is built, endow the micro service and its dependencies with dependency weight, and offer a dynamic update mechanism of the dependency weight ,then deploy a corresponding number of multilayer dependencies according to the dependent weights when need to deployment the micro service. Finally, it compared and analyzed the actual effect, the results show that this method can effectively reduce the times of micro-services dynamic deployment and guarantee the minimum violation rate of service-level objectives.
Keywords: cloud computing, microservice, dynamic deployment, SLA, dependency, service level agreement
