From Legacy to Microservices: A Case Study on Automatic Investment at LHV

Abstract

Microservices are a popular choice as an enterprise application architecture because they offer many benefits when compared to monolithic applications. Monolithic application is a good choice when an enterprise is small, but as the engineering department expands, the monolithic architecture drawbacks become even more visible. Then comes a moment when a monolithic application needs to be split to make use of the microservices architecture. This study is a case study in a large banking enterprise where a part of monolithic application was migrated to a microservice.
