As per this principle, Any Microservices should be continuously deployable, meaning that they should be updated frequently with small, incremental changes like bug fixes, small enhancements etc .

For example, a microservice could be updated to fix a bug or add a new feature, without affecting the rest of the application.

Continuous deployment is achieved through a combination of techniques such as automation of build and deployment processes, testing, and integration with other tools such as version control systems, issue tracking systems, and monitoring tools.

By automating the deployment process, teams can ensure that new changes are deployed quickly and consistently, with minimal human intervention.

This practice also helps to reduce downtime and minimize the risk of errors, as new changes are thoroughly tested before they are deployed to production. Furthermore, it allows organizations to release new features and bug fixes more frequently, which can result in increased innovation and faster time to market.
