From monolith to microservices

In the beginning, there was the monolith... and computer applications were designed as unified and indivisible blocks.

While this type of architecture was the norm for IT projects and remains recommended for simple applications (or MVPs), the development of microservices architectures has experienced significant growth over the past ten years.

Indeed, more and more developers are designing architectures made up of a set of small services that can be deployed independently and autonomously: microservices.

In a microservices architecture, services communicate with each other to provide global functionality.

This approach has several advantages:

  • microservices allow better fault tolerance: if a service is down, the other services continue to operate allowing better availability of the application

  • microservices improve the scalability of an application: it is easier to evolve or scale a particular service of the application without affecting other services.

  • microservices allow greater flexibility in software development: each service can be developed, tested and deployed independently of the others and are therefore easier to maintain and update.

  • developers can work independently on microservices. We can thus have microservices in different technologies (Nest.js, Laravel...) and it is not necessary to understand the entire product to work on a particular service.

These advantages mean that microservices architectures are increasingly used by companies that want to create applications that are easier to maintain, more scalable and more reliable.
