Monolith architecture has been very successful in shaping the software world the way we see it today. However, the last few years have seen a sharp decline in its adoption, especially with the advent of Microservices. The popularity of microservices was caused by the need for scalability and changeability which in turn is caused by the penetration of IT in almost every entity, animate or inanimate. Modern applications see no boundary when it comes to scaling and these applications are fond of change and this is where Monolith doesn’t fit at all.
Microservices, at least in theory, is “The Silver Bullet” that will solve all the problems and will serve humankind till eternity, but it doesn’t happen. Microservices bring lots of challenges that were nonexistent earlier. Still, what it does, it does it beautifully and efficiently and most importantly serves the purpose.
