Microservices play an important role in minimizing the time which is required for software application projects which will in result maximize the reliability of backed data in the systems. APIs plays an important role in microservices and also provides the best practices and strategies for designing APIs. Microservice architecture is working in a revolutionary way in which various enterprises build their infrastructure which is technical in nature to develop new applications. It works a major factor in the success of various web businesses and spreading to other well established Companies at a high pace focusing more on innovation, application economy. Monolithic applications in microservice architecture are relinquished in lightweight microservices which delivers a set of functions. New applications and services can be quickly developed by combining a set of services and functionalities.
The infrastructure components must interact with each other. Each microservice must interact with the other microservice component in the architecture as well as in the websites and applications that draw real time information which is very essential for their working. Each microservice must have their interface which is further considered as an enabler of microservices. They are based on open networking principles of various APIs which further provide the logical and proper model for building interfaces between components and architecture. The design of microservices should reflect the essence of architectural practices. It should have an essence for coding microservices themselves. There are two types of characteristics which are also key design which are as follows:
Message oriented API in which services can be updated with other components of the system. It is very important for the API to connect these components with safe refactoring. Following this approach makes it possible to show the general entry points and receives task specific messages which also allow changes in message content in the way of refactoring components over time.
Hypermedia API in which the messages passed between the different components is more than data which includes descriptions which means that data is loosely coupled. It is essential in loose coupling in a microservice. It is comparatively new and that is why, it lacks mature tooling and support which is required for microservice.
Microservices benefit from the collaboration and highly decentralized form. Design data is very weak to succeed in such an environment which is full of challenges.
