Building Microservices With Node.Js

Microservices are a variation of Service-oriented architecture, which are trending these days. This architecture has been embraced by many projects because it’s easy to adopt and work on. Applications these days are becoming more and more complex with the increase in the demand of information. The visualization part of the information is facing a huge shift to new data visualization sources and devices. With new emerging technologies, people expect an application to able to integrate with today’s cyber lifestyle.

Another thing about the applications is that when they grow in size, issues like code-maintenance, bug-fixings and upgradation to new features arises. Sustainability and Scalability of such applications can be efficiently and effectively managed by using microservice architecture.

Microservices rely on a very simple strategy that is to break every complex service into a small, simpler service that is aiming for common functionality. The idea is that services should be granulated and light – so granulated that they can be easily maintained, developed, and tested, and so lightweight that they can be responsive and scale more easily. Thus, we try to break big and monolithic design into small, independent programs which interacts with each other keeping information in sync to carry out the operations.

Some of the pros of this architecture are as follows:

• Application Maintenance: Services becomes easier to develop, test and deploy when fragmented properly. This way they are simple and manageable.
• Design enforcement: A proper and good design is enforced on the application being developed.
• Knowledge encapsulation: Services will have specific objectives, such as delivering emails, which will lead to service re-usage and knowledge about specific tasks being grouped together in services.
• Technology agnostic: Each service can be developed using the best tools and languages to build it correctly.
• Performant: Services are small and lightweight, and, as mentioned previously, use the best tools available.
• Upgradable: Services should be interchangeable and upgradable separately.
• Application response and productivity: When complexity starts to grow, productivity declines. With Microservice architecture has a great edge over a monolith application in this respect.
• Application response and productivity: When complexity starts to grow, productivity declines. With Microservice architecture has a great edge over a monolith application in this respect.

There are also costs associated with this architecture, namely:

• Service Dependencies: Because of this architecture being technology agnostic, different dependencies for different services may arise.
• Application Performance Complexity: For small applications, the bootstrap complexity is bigger compared to the monolith architecture.
• End-to-end app testing: It becomes more complex to test the application from end to end as the number of services interconnecting are definitely bigger in microservices than in a monolith application.

In addition, every microservice can be written using the language, technique, or framework that’s most appropriate to the tasks it will perform. Hence, our development team access your requirements a
