API & Microservices

API & Microservices

For a software platform divided into microservices to work, it is necessary that the components of the infrastructure interact with each other.

Each microservice must be able to exchange individually with all the other microservices in the architecture as well as with third-party applications, databases, analysis tools, etc.

Micro-services architecture & API

These synchronous or asynchronous communications are essential. This is why a microservices architecture requires APIs which formalize interaction possiblities.

Each microservice must have its own API. The correct definition of these APIs is necessary to leverage all the advantages of a microservices architecture :

  • Independence when deploying functionalities of the platform,
  • Better fault tolerance,
  • Compatibility with containerization,
  • Easier implementation of continuous delivery and continuous integration,
  • Better load balancing in a cluster,
  • Better team autonomy by allowing the use of Feature Teams.

In the API field, RESTful concepts provide the most logical model for building interfaces between the various components of a microservices architecture.
