Kas saaksite selgitada madala sidususe kontseptsiooni ja selle olulisust mikroteenuste disainimisel?

Low coupling is a design principle where system components depend minimally on each other. In the context of microservices, this means each service operates independently, has a clearly defined interface, and does not depend on the internal implementation of other services.

The importance of low coupling in microservice design:

• Simplifies support and development — changes in one service do not require changes in others.
• Increases fault tolerance — failure of one service does not cause the entire system to crash.
• Flexibility in technology choice — each service can be implemented in an appropriate language and with suitable tools.
• Accelerates development — teams can work in parallel on different services.

To achieve low coupling, it is important to use clear APIs, asynchronous interaction (e.g., via messages), and avoid direct calls to internal components of other services.
