Microservices architecture design
is a kind of complicated thing to start, afterwards it serves as a mightful benefit for application maintenance and further scaling and enhancing. Moreover, microservice-based applications are a priori cloud-native, allowing implementation of the best DevOps practices.
Each company distinguishes its own benefit using such architectural style, but the most common advantages are:
Each module is independently deployable. No need to prepare the entire application architecture to deploy.
Since all the modules are isolated, they become independent from each other. It brings clarity and "transparency" into the whole infrastructure.
- Faster defect identification and recovery
Monitoring tools can quickly identify the failed module and you will be able to isolate it at once for further recovery.
- Less risks and fault tolerance
The full application wouldn't crush if a module goes down. It will just continue working as usual.
- Easier integration with third party services
No need to refactor the entire infrastructure to implement new tools.
Microservices can be developed using almost any programming language. The most widespread are Golang, Java, Python, Ruby, NodeJS.
If there is such a need, you can upgrade a single service instead of upgrading the entire system.
