The microservice design pattern

・The microservice design pattern

The microservice design pattern is fit to the agile development process and the Microsoft Azure provides it’s runtime environment as the Microsoft Azure Service Fabric. The architecture is considering partition tolerance same as a distributed system. This article describes microservices, one of a distributed system, is not manages state at persistent tier but at middleware tier.

If you want to read detail of state machine or state management, please refer to Some patterns of transferring state of system.

When system is used by few users, the system shares state at persistent tier is not prompting problem, but a lot of users access system, state of information will conflict and many optimistic lock occurs. As generally, design a processing break down, or short transaction mixing, because a grand design of persistent tier takes large cost.

The microservice desing pattern is one of the design pattern for it. Therefore microservices communicate each other and have each persistent tiers respectively. It is important for designing microservice that is distributed system.

So, state transferring of common N-tier system from state full UI-tier to state less function tier is designed in microservice design pattern to state management at state full middle ware.
