Why Microservices? When should you use them?

Traditional Architecture Vs Microservices Architecture

Generally, in traditional architecture, multiple features are built into a single application or a single database. Adding new features introduces dependencies because it is managed as a single package. When we speak of Microservice architecture, each feature is built-in isolation and is independent of all the other features where Http REST or Message Bus is used to allow these services to communicate individually. Yes, it seems very complex and a lot more work, so why would I want Microservices?

Similar to breaking down tasks to accomplish a goal, applications are broken down into smaller services, hence the name, Microservices. Large monolithic packages are created while using traditional architecture which is challenging to deploy and is generally hard to manage. This makes deployment a drama, so we deploy seldom or once every few weeks and sometimes months. Microservices are small and isolated which are packaged and deployed independently of each other which makes configuration easier to manage which in turn allows us to deploy more often. Deployment is now uncomplicated and, in some cases, takes place multiple times a day. One other time that microservices comes to the rescue is when the applications become popular. Due to an increase in load and storage capacity, traditional architecture ramps up more hardware and utilizes more servers. While this increases costs and adds up to the workload, Microservices ramps up only the instances of the services that are needed which saves resources by balancing the load on multiple servers.

Due to these positives, all companies ranging from start-ups to MNC’s are adapting to this and transitioning. This is a reason for the boost in demand for IT professionals that have worked or are working with Microservice architecture.

After steady research, these are the 5 best languages needed to successfully deploy and maintain Microservices:

1. Java
2. Python
3. C++
4. NodeJS
5. .Net

There is an increase in resilience due to the isolation of features which allows handling events when the other services fail. Microservices, without a doubt, might be more complex or require a stronger collaboration during deployment and not everything might be suited to Microservices but overcoming this barrier will ease up the workload while saving resources and keeping up to date.
