Increased operations effort #

• The operation of a microservice system requires more effort than running a deployment monolith.
  • This is due to the fact that in a microservice system, many more deployable units exist that all have to be deployed and monitored.
  • This is feasible only when the operation is largely automated and the correct functioning of the microservices is guaranteed via appropriate monitoring.

Must Be Independently Deployable #

• Microservices have to be independently deployable. For example, dividing them, into Docker containers is a prerequisite for this, but it is not enough on its own.
• Changes to interfaces must be implemented in such a way that an independent deployment of individual
