How do you divide microservices?
Step 3: Split the monolith to build a microservices architecture
- Keep communication between services simple with a RESTful API.
- Divide your data structure.
- Build your microservices architecture for failure.
- Emphasize monitoring to ease microservices testing.
- Embrace continuous delivery to reduce deployment friction.
Should microservices depend on other microservices?
If possible, never depend on synchronous communication (request/response) between multiple microservices, not even for queries. The goal of each microservice is to be autonomous and available to the client consumer, even if the other services that are part of the end-to-end application are down or unhealthy.
How do you convert microservices to monoliths?
Migrating from Monolith to Microservices
- Identify logical components.
- Flatten and refactor components.
- Identify component dependencies.
- Identify component groups.
- Create an API for remote user interface.
- Migrate component groups to macroservices (move component groups to separate projects and make separate deployments).
Why is it bad to use shared libraries in microservices?
If you’ve read a bit about microservices, you’ll probably have come across the mantra, “Don’t use shared libraries in microservices.” This is bad advice. While the sentiment is borne from real issues and there’s real wisdom to be gained in this area, this little statement is too pithy, lacking the relevant context to make it useful.
When are shared libraries an issue in application design?
When they create coupling. Specifically with regard to shared libraries in microservices, coupling happens when the use of a library in one application applies strong force on integrating applications to also use the same library and/or platform. When are shared libraries an issue in application design?
Why do we need to create common libraries?
The creation of our own “common” libraries creates coupling between the projects that depend on them because of the following reasons: The “common” library may contain complex logic which all the microservices depend on.
Why do microservices use the same domain model?
Besides, in a microservice architecture, every microservice should be a bounded context anyway (see domain-driven design). Therefore, a microservice should have its own domain model. So there should be no reason for another microservice to use exactly the same domain classes.
