After Netflix, Soundcloud, Amazon and a few other tech giants shifted from Monolith and opted the Microservices, this development technique has gained a lot of attention from large to small tech startups.
Monolithic Architecture has multiple advantages and that’s why it was an ideal choice of any software development architectures. Some of them are
- Ease of Development – It is very simple to develop a goal of the development tools and IDs is to support the development of the monolithic application, it makes it easy and one direction.
- Ease of Deployment – You have to deploy the executable file only at the run time – It can be War file.
- Easy to scale – To scale, you have to run multiple copies behind the load balance hence it is easy to scale your application.
Cons that micro services took over this architectural technique:
- Slow Development – When it is a large application and a number of teams working on it so it becomes very hard to understand and modify, larger the codebase leads to slower the ID, the codebase is large for the obvious reason because the entire application is monolithic. Large monolithic application has been always an obstacle to frequent deployment.
Just to update one component you have to re-deploy entire application which increases the task over and over. Taking over all these disadvantages that were daunting enterprises, microservices technique allows a large application to broken down into small multiple services that together form a large system.
Single services can focus on single capability which leads to better quality and performance of the entire application. They may not share the data structure but can communicate through APIs. All the components are kept in separate modules, unlike the Monolithic architecture. Here every service is responsible for its own data module as we have multiple instances hence it decreases the dependency.
With so many advantages over the monolithic architectural framework and having introduced over a decade to the companies are still uncertain whether they want to opt it. Reason being its disadvantages like:
- In the fast-paced environment, people are reluctant to embrace a cultural change.
- Operational Overheads expense increases while dealing with a distributed system, even the cost of maintenance is much higher.
- It increases the memory consumption because each service runs in its own runtime environment.
Microservices says “Do one thing at a time and do it well”, though microservices have now become common practice for the enterprises to achieve agility, increase the performance of end product, we can not deny that it comes with risk. Introspection, understanding, and planning is the key to success if you opt this method.
