Microservices is an architectural style that structures an application as a collection of loosely coupled services, each of which implements a business capability. This approach enhances flexibility and scalability, allowing for the independent deployment of services, which can be developed, tested, and deployed independently by different teams.
The microservices architecture is particularly useful in large, complex applications where the agility and speed of deployment are crucial. It allows organizations to scale specific components of an application without impacting the entire system, improving resource utilization and resilience.
In the methods-and-patterns quadrant of the Tech Radar, microservices are classified in the adopt ring, indicating that they are a well-established practice with proven benefits. Many organizations have successfully utilized microservices to achieve greater modularity, fault isolation, and faster time-to-market, making it a crucial pattern in modern software development.
