With the introduction of developer tools and platforms like Docker, AWS, GitHub etc, the software development process has become too easy. You have a monolithic architecture and three million lines of code. Making changes and rereleasing whenever you want to update your application with new features is not an easy task. It not only creates dilemmas between the developer teams. Finding the mistake that is causing the code to break is a huge task.
So, why not move to microservices architecture? Why break your head every time you want to make changes to your codebase? This is too complex and irritating.
Recently, many companies have moved from their monolithic architecture to microservices architecture. There are many advantages of shifting to microservices architecture.
While a monolithic application puts all of its functionality into a single process and scales by replicating on multiple servers, a microservices architecture breaks an application down into smaller applications and then segments them by logical domains (i.e., authentication, user directory, reporting, checkout, etc.). Together, microservices communicate with one another over APIs to form what appears as a single application to end users. Isn’t this a cool concept?
Embracing automation and DevOps is a must when you want to move to microservices architecture. This will happen with the use of Continuous Integration and Continuous Deployment tools by following a solid Continuous Delivery pipeline.
We have seen this happen; when things go wrong, operations blames development and development blames QA. This happens in organizations that are still using old methods. Since the mistakes are invisible, there begins a blame game.
Microservices architecture is where different pieces are loosely coupled and are made to communicate with each other without breaking anything. Adopting to microservices boosts knowledge across different teams to work on a single piece of application with full responsibility. This is where different microservices have their own tasks to do that are independent of each other. This makes it easy to find out what broke where and who introduced a particular bug, making mistakes easier to fix.
Microservices architecture is simple to develop, test, deploy, and scale.
In conclusion, here are a couple of advantages of microservices architecture.
Embraces DevOps and automation.
Reduces the complexity of writing large lines of code.
Improves the communication between development, QA, and testing teams.
Makes it easy to find bugs and address them quickly.
Faster startup time thanks to lightweight servers.
Each service can scale independently.
