Microservices can be deployed in different ways. Microservices usually ship with containers such as packer, Dockers, or for Amazon Web Services (AWS), one can also use Amazon Machine Image (AMI) to ship the microservice. However, AMIs take longer to create and deploy than Dockers, and Docker is a better tool for deploying a microservice. Proper versioning rules should be in place; otherwise, the whole architecture will be in a versioning hell. Typically, xx.xx.xx is the versioning format. The right most is for smaller bugs or patches, while the middle section increases by adding any new feature in the component. The left most number increases when you have changed something big, like the communication interface model.

We will talk in detail about communication between services and deployment in the upcoming chapters.
