Using an example, explain how Microservices Architecture facilitates continuous delivery practice across development teams.
Continuous Delivery practices encourage incremental additions as part of production. These additional features and capabilities are made possible by the separation and independence of services in a microservice architecture. An example of this is seen in the ability to fix bugs in a microservice architecture. A feature that handles a bug can be independently deployed, and the service can be updated without interrupting the process of continuous delivery (i.e. other service developments are unaffected).
