The systems and architecture are building for so many years, and with each passing decade, we are evolving and improving them. The world has developed technologies, robust architectural patterns, and best practices to develop applications with optimized structure and great ease. Microservices-based architecture is one of the architectural patterns that has evolved and helped the industry. Microservices are one of the coolest and most affordable trends in modern enterprise application development. Let’s explore more about Microservices Architecture with Node.Js.

What are Microservices?
Microservices, also known as Microservices-based architecture, is a single self-contained unit that, together with others, makes an extensive application. Instead of massive applications with complicated infrastructure and heavy maintenance, microservices-based architecture simply breaks down the functionality into a small suite of services integrating the application via APIs. The approach empowers elements of the application to be updated and scaled separately.
Microservices-based architecture lets you split your application into small units. Each part can independently deploy and scale; it does not matter if different programming languages and teams write it. You can also test the small units individually.
On the other hand, microservices is a component-based model, a way of delivering composable applications with the help of well-documented, explicit APIs. It is a significant way of designing applications but not at all an effective way to deliver. Now each web server requires a separate instance to run a separate service on a server. Suppose you plan to build a high-density set of services, where services are running one separate container. This is where microservice takes place to replace the heavyweight Apache with a service-oriented item.
Examples of Microservices:
Let’s look at some of the enterprises that use Microservices.
Amazon is the best example to take into consideration. At Amazon, the DevOps team is responsible for maintaining and building services to run the website with the help of 200 or more services. Here the microservice model is used to improve the website’s performance.
Just like Amazon, the journey of microservices at Netflix began in 2008 before microservices attend popularity. In 2007, Netflix offered movie-streaming, and after a year, Netflix chose to use microservices as it started facing scaling challenges and suffered from service outages.
Uber struggled to build new features and fix bugs in its existing platform, which became an obstacle in integrating its global operations. Additionally, Uber’s monolithic architecture required developers with immense experience just to make minor changes, update, and fix bugs. The solution Uber found for all their struggles was to use microservices.
The Node.Js Platform
With the help of Node.Js, one can build applications with faster performance and handle simultaneous requests. Many platforms like Trello, PayPal, Netflix, LinkedIn, Uber, Netflix, Medium, eBay, etc.
Key benefits of Node.Js
- Highly scalable: Servers have the capability of handling multiple requests simultaneously.
- Event-driven: ‘Events of Node.Js’ – notification system enabling the server to capture the response of the previous requests.
- Asynchronous: The Async behavior of Node.Js doesn’t await the return data of the previous request.
- Buffer-less: No buffering as data is released in the form of chunks.
- Single-threaded: The server makes use of the non-blocking mechanism for responding to requests with the help of event looping.
- Super-fast: Code execution is super fast.

Top 5 reasons for using Node.Js for Building Microservices
Node.js supports several Microservices framework that enables the development of application based on microservices strategy. Senaca.js is amongst the most popular creative environment for the development of microservice-based applications.
1. Top-notch Performance
The event-driven Node.js I/O model, along with microservices strategy, can perfectly handle a significant amount of load with minimal response time.
3. Developer Friendly
Node.js holds a very massive community, and it is backed by millions of programmers across the world. NPM – Node package manager contains more than 4 million ready-to-use modules. Along with the faster development of applications, it is easily scalable throughout the application development life cycle.
4. Easier Maintenance
Maintaining the code is easier as it doesn’t have complex monolithic code. Developers can add new features in a streamlined and straightforward manner. They can also easily update instead of re-writing.
5. Uninterrupted development workflow
Developers can work on their respective sections of the application rather than interrupting their development workflow.
Common Rules of Microservices
Any microservices system has hundreds of different services. A manual configuration of ports, API capabilities, and IP addresses is not convenient.
The system should be graceful enough to deal with miscommunication, timeouts, errors in message processing, and more.
3. Self Healing
It’s normal to occur failures. The implementation should inevitably recover any functionality and recover any lost service.
The service should identify new services newly introduced to the system to start communication without the downtime and manual intervention.
If your microservice architecture determines the capabilities mentioned above and you’re almost fluffing most of your API request into several independent services, congratulations dear that you are doing microservices.
In this blog, I have tried to explain why microservices with Node.js is the right choice when it comes to implementing the architecture. Ease of development, cost of control, and painless scaling, Microservices has numbers of benefits to offer. The combination of microservices and Node.js perfectly work together in high-traffic and complex applications. If you are thinking that your business idea is a perfect fit for microservices, then hire Node.js developer from us to leverage our expertise to rewrite your existing applicatin to be perfectly suitable for the digital age.
Is NodesJS good for microservices?
Absolutely! You can opt NodeJs for building your microservices. It is more beneficial as it helps to develop the application smoothly and quickly. Moreover, it fits perfectly with real-time app development and I/O-based apps.
The combination of Microservices and NodeJS is best for complex applications with high traffic, which you may find difficult to maintain and develop as monoliths.
Which languages are best for Microservice?
Here are the top 5 languages for Microservices-
What are the advantages of Microservices?
The following are the advantages of Microservices-
- Easy to adopt new process or language.
- The application breaks down into smaller modules on which developers can work respectively.
- The failure of a single module will not affect the entire application.
- Every service in the architecture is capable enough to be Deployed, Updated, Replaced, & Scaled independently.
What is the difference between APIs and Microservices?
Microservices is defined as an approach for developing an application .i.e., breaking down the application into small chunks and make it modular, independent, and self-contained. It simplifies the development and maintenance process.
API is a section of an app that is used for communication with other applications or the server. It consists of a request and its response.
Why should you choose Microservices?
Here are some reasons for choosing microservices-
- To easily comprehend the large-structured and complex applications.
- To avoid deploying the entire application if there’s a small change
- Supports modularity and independent development
- To avoid slowing down the start-up time as it happens with monolithic applications
- To minimize the impact of alternations and changes
