Microservices are an IT architecture and development strategy in which an application is divided into several independent components or services that communicate with each other via interfaces (APIs).

Modular system structure

These services are specialised for a particular function or task and can be developed, tested, deployed and scaled independently.

In the context of best-of-breed, this means that each component of the system represents the best available technology for the specific requirements. Using standardised interfaces and a API-first approach, these individual services can be easily integrated with each other to create a complex application. This allows for greater flexibility and agility in application development.

Microservices and cloud-native

The combination of microservices and Cloud-native enables companies to develop, deploy and scale applications in an agile way. By using cloud-native technologies, microservices can be packaged in containers and orchestrated in the cloud. This facilitates horizontal scaling and automated management of services.

Microservices in the MACH principle

The MACH principle stands for microservices, API-first, cloud-native and headless concept. The use of microservices creates a modular system structure. The independent modules are functions or services that can be developed, updated or scaled separately.

Advantages of microservices

The advantages of microservices include better scalability as each service can scale independently, greater flexibility in developing and integrating applications, and better maintainability and resilience.

Disadvantages of microservices

The disadvantages of microservices are that it increases the complexity of architecting and managing many small services and that implementing interfaces can be time-consuming. In addition, it can be difficult to ensure consistent data management across different services.
