Research And Implementation Of VM Orchestration System Based On Microservices

The emergence and continuous advancement of virtualization technology promotes the cloud computing industry.At present,people do not care about the infrastructure such as server and networking devices any more because of IaaS,PaaS and SaaS which public,private and hybrid cloud provided.There's also no need to spend much time on deploying platforms such as operating systems,middlewares,databases,etc.Public clouds even provide products to replace manual deployement and configuration.The paper designs and implements the Virtual Machine Orchestration System based on Microservices.After choosing the templates and filling the parameters,the system can generate an optimized confuration using scheduling algorithm called Topological Sort Algorithm,which leads an efficient ochestration.Since Microservices is lightweight and can easily provide a complex service through simple HTTP requests,the system consists of User,Basedata,Template,Ochestration and Message service centers which implements the core and other basic business functions as designed.The orchestration system also combines current internet technology to achieve high concurrency and high availability,which meets the requirements of function and performance testing.The enterprises,especially IT enterprises or departments are facing the challenges of lots of platform orchestration.The system can resolve the issue in their daily development,testing,operation and maintenance,record the virtual machine configurations after orchestrtion.Automated orchestration can also bring great efficiency to users.
