Building a Dynamic IT Landscape with Microservice Architecture
Advantages of microservice architecture
Best practice software regardless of technology
Microservices allow for technology diversity and the use of best practice software regardless of the technology.
Continuous system replacement
Build your architecture to be able to replace systems continuously and at different paces.
Robustness - one failure doesn't bring everything down
Through clearly defined interfaces, an error can be isolated from the rest of the services.
Performance optimisation and scalability
Unlike a software monolith, the performance of microservices can be optimized down to the individual service.
Time to market
Rapid deployment of new code and features. With microservices, you can deploy each service independently.
With microservices, you can naturally divide responsibilities among teams, allowing smaller teams to individually handle tasks from development to deployment.
How do you phase out legacy software with microservices?
There are several variations of the method described below, but to keep the explanation simple, let's stick to the general principle of replacing a service or a piece of software.
