In large applications consisting of loosely coupled microservices, it makes sense to design the internal architecture of each microservice to suit its function rather than adhere to a single top-down architectural approach.
By design, each microservice is an independent entity that has its own data as well as business logic. So it’s intuitive to use a design approach and architecture that’s best suited to its requirements, irrespective of high-level microservices architecture. However, detractors would like you to believe that using multiple languages should be avoided as it adds unnecessary complexity and overheads to microservices operations.
But there are multiple use cases where multilanguage architecture makes sense, and technology can be used to efficiently manage the overheads introduced. In this article we will unpack:
- When to build multilanguage microservices.
- The challenges introduced in microservices communication due to the use of multiple languages.
- Some tools and techniques to make multilanguage microservices implementation easier.
