Migrating Legacy Software to Microservices Architecture

Abstract

As a legacy monolithic software become too large to deal with, many enterprises are drawn to breaking them down into the microservices architectural style. Migrating a monolithic architecture to an ecosystem of microservices is an epic journey. Each legacy monolithic application is unique and migration to microservices creates different challenges. This article elaborates on challenges and technics of legacy software migration from monolithic architecture to microservice architecture. Different migration methods and techniques are reviewed, and their benefits and drawbacks are analyzed. Microservices is a relatively new architectural style and legacy monoliths are very different in many aspects. Existing migration techniques and methods do not cover every use case.
