Growing customer demands have increased the need to build large scale and complex applications meeting the requirements of end users. Microservices have changed the way traditional and legacy applications were built. Unlike the monolithic architectural style, microservices architecture helps to bring business agility and improve time to market.
Microservices architecture splits the single application into a set of services, each running on its own but communicating with each other through APIs.
Microservices architecture is business-oriented, adaptable and loosely coupled. Loose coupling promotes greater reusability and easier maintainability.
Software teams do not just want to leverage technology, but also go to market faster with minimum iterations. With conventional monolithic architecture, this is difficult to achieve as it is time consuming and challenging to maintain.
Microservices architecture has settled this problem and makes it possible to build loosely coupled services that could be scaled, changed and easily managed.
Moreover, microservices enable DevOps and help companies to focus on zero-downtime, continuous integration and deployment. With so many benefits, microservices are here to stay for long.
The Primary benefit of the microservices architecture is its loosely coupled components. These components can easily be developed, replaced and scaled separately.
As complex applications are broken into distinct service components and deployed on multiple servers, the defect of one of the services will not impact the entire application. Microservices improve fault isolation.
Compatible with Distributed Environment
Understanding how an application is developed is crucial when there is a transition in development teams. In a distributed development environment where some of the team members are geographically dispersed, microservices architecture make it easier for development teams to understand the entire functionality of a service as it is not built into one single package.
Re-usability of services
Microservices are organized around business capabilities instead of a specific project or product requirement. This allows technology teams to reuse services and reduce costs.
Easy to Deploy
Technology teams usually have to deploy an entire application again because of small change in the code. However, microservices makes it easy to deploy. The extent of deployment is less and the service that has an issue needs to be handled.
With more and more companies now resorting to iterative development, it is essential to have an underlying architecture which is scalable, robust and adaptable to real-time business needs.
