Agility Through Modular Architectures - From Modular Monoliths to Microservices

No single architectural style solves all needs. Though microservices have taken the developer community by storm recently, they are not always the optimal solution. In some cases, a more monolithic architecture may be more suitable short term. Or perhaps a more traditional system of web services that allow you to leverage existing infrastructure investment is preferable. Fortunately, proven architectural practices allow you to build software that transcends specific architectural alternatives and develop a software system that gives the development team the agility to shift between different architectural styles without undergoing a time-consuming, costly, and resource intensive refactoring effort. Modularity is the cornerstone of these alternatives.
