Why is service isolation important in a good architecture?

Service isolation plays a critical role in maintaining a robust and flexible architecture. One of the main advantages is that it promotes independent lifecycles for different services. By isolating services, teams can develop, deploy, and scale them independently without impacting the functionality of other services or components. This independence facilitates easier refactoring since changes in one service do not necessitate changes in others; you can modify or upgrade a service while keeping the overall system functioning seamlessly.

Moreover, service isolation simplifies testing and debugging processes. Isolated services can be tested independently, enabling developers to pinpoint issues more effectively and ensuring that each service performs its intended function without interference from others. This isolation ultimately leads to greater agility within the development process, allowing organizations to adapt more quickly to changing requirements and technologies. As a result, promoting independent lifecycles through service isolation fosters a more maintainable and scalable architecture.
