A microservices architecture is an approach used to develop software applications in a number of small services. Each of these runs autonomously and communicates with each other. But the real question is: why are they useful in the process?
The first thing to mention is that this architecture method is compatible with multiple platforms such as Iot, web, mobile, wereables, among others. It is a good system when the type of devices to which the work is oriented is uncertain.
The second point to note is that microservices are used to create larger and more complex applications. That is, the end result could be better development and managed as a combination of small services that work together.
But how does one service communicate with another? The most important thing is to understand that part of the implementation of microservices depends on the skills of the implementer and system preferences. There are those who use HTTP/REST with JSON or Protobuf, but the REST method is the most highlighted by the learning curve.
Benefits of the microservices
- With such an architecture, implementing new technologies or processes is easier.
- The application will be divided into more parts, which makes maintenance and development more bearable.
- Each service can be DURS independently: (implemented, updated, replaced and scaled).
- When a module is affected, it will not affect other applications.
It is also important to know what criteria should be taken into account when choosing a microservices technology. This tool comes with an operational overhead and it is necessary to standardize this by choosing the right technology.
Here are some of the criteria for evaluating the programming language for microservices development:
- Support for the automation.
- Focus on the consumer.
- Modeling around the business domain.
- Decentralization of components.
- Support for continuous integration.
