It is considered a best practice for cloud engineers to design microservices to be loosely coupled and highly cohesive for several reasons:

1. To develop, test, deploy, and update each microservice independently, without affecting the rest of the system: By designing microservices to be loosely coupled, changes or updates to one microservice can be made without impacting the functionality of other microservices. This allows for faster development and deployment cycles, as well as easier testing and debugging.

2. To ensure interoperability, reliability, and security of the system: Loose coupling allows for better interoperability between microservices, as they can communicate with each other through well-defined APIs. It also enhances the reliability of the system, as failures in one microservice do not propagate to other microservices. Additionally, by keeping microservices separate and independent, the security of the system can be better maintained, as vulnerabilities in one microservice do not compromise the entire system.

3. To gain useful insights into the behavior of the system: By designing microservices to be highly cohesive, each microservice focuses on a specific functionality or business domain. This allows for better monitoring and analysis of the behavior and performance of individual microservices, providing valuable insights into the overall system's performance and potential areas for improvement.

4. To simplify the complexity of managing many containers across different environments: Microservices architecture often involves running multiple containers across different environments, such as development, testing, and production. By designing microservices to be loosely coupled, it becomes easier to manage and scale these containers independently, reducing the complexity of managing the overall system.

In summary, designing microservices to be loosely coupled and highly cohesive enables independent development and deployment, ensures system interoperability and security, provides insights into system behavior, and simplifies the management of containers across different environments.
