Microservices architectures seem to be the new trend in the approach to application development. However, one should always keep in mind that microservices architectures are always closely associated with a specific environment: Companies want to develop faster and faster, but resources are also becoming more limited, so they now want to use multiple languages and approaches. Therefore, it is difficult to evaluate a microservice architecture without reference to the environmental conditions. However, if you separate these external factors, you can still see that a microservice architecture offers much more isolation than other architectures – and can also handle security measures better than, for example, monolithic approaches due to today’s techniques and tools.
