With the microservices architecture gaining a lot of traction in the software world, more and more companies are migrating from their existing monolith to microservices architecture. Typically, this is a wise move, but great care needs to be taken in order to complete this process successfully. Below, we have gathered the nine most common issues we see when working with our customers on monolith to microservices migration.
1. Having nothing to migrate from
While in some specific systems it might make sense to start development with a microservice architecture, typically it is better to start off with a monolith with well-defined module boundaries and migrate to microservices when the product is more mature. During early development, the approach, requirements, and designs shift a lot. Plus, based on market response, product managers might decide to pursue a different market or niche. Additionally, decision-makers frequently do not have a complete understanding of the requirements from the beginning of the project.
