Encapsulating business logic into microservices

The backend design for web services is usually referred to as distributed architecture because you expect to have service components running on different processes and physical servers. Each service component is accessed remotely through a sort of remote-access protocol. These service components can communicate with each other across different processes, servers, and networks. Similar to Object-Oriented Design (OOD) in software architecture, distributed architecture accommodates more loosely-coupled, encapsulated, and modular design for Web Service applications. Such characteristics of distributed architecture are generally advantageous to cloud backend services as they bring better scalability, modularity, and control to the development and deployment of service modules.
