Challenges
Understand the critical challenges involved in deploying and operating microservices such as increased operational effort, the necessity for independent deployment and testing, coordinating multi-service changes, and managing system complexity. Learn to weigh these challenges against the benefits to determine when microservices are the best solution for your projects.
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
