The microservices architecture is widely regarded as a promising approach to service-oriented systems. However, developing applications in the microservices architecture presents three main challenges: (a) how to program systems that consists of a large number of services running in parallel and distributed over a cluster of computers, (b) how to reduce the communication overhead caused by executing a large number of small services, (c) how to support the flexible deployment of services to a network to achieve system load balance. This paper presents a programming language called CAOPLE and reports the implementation of the language on a virtual machine called CAVM-2. The paper demonstrates how this approach meets these challenges.
