Microservices with NodeJS: Benefits & 6 Best Practices

What is Microservice Architecture?

Microservices or Microservice architecture is a type of service-oriented architecture (SOA) in software application development where the app is built from a collection of interconnected services. Microservices decompose the app into smaller services, allowing for greater modularity.

What are the advantages of implementing microservices?

Well, there are several obvious, concrete advantages to using Nodejs microservice architecture for custom mobile app development services, which we’ll go through below.

The relation between NodeJS and microservices

The relationship between NodeJS and microservice architecture is extremely strong. Node was built specifically to enable the development of microservice-based apps easier. Its name was chosen to emphasize this link: it’s meant to express the idea that Node apps should be made up of several small distributed nodes that communicate with one another to function.

Why use Microservices with NodeJS?

Node.js is well suited for microservices. Node.js is super fast while execution, single-threaded, event-driven, highly scalable, with asynchronous libraries, and also buffers less.

Effortless Development

Large-scale systems are challenging to understand, conceptualize, build, and sustain because they are complicated. With NodeJS microservices, it would be exceedingly simple to update, deploy, and manage the system if you split it into smaller, independent components using microservices.

Cost-effective and faster time to market

Node.js is highly suited for microservice architecture, allowing developers to build small components that smoothly fit into a continuous delivery pipeline to expedite an app’s time-to-market.

Node has a built-in webserver

A web server is included with JavaScript. You won’t need to deal with another Nginx or Apache instance. As Node, you can also say goodbye to things like FPM. js is a single-threaded language.

Simple Updates and maintenance

Node.js takes a modular approach to application development, allowing developers to make use of microservice architecture for quicker, easier, and incremental upgrades.

User-friendly- Simple to install, integrate, and maintain

In comparison to Java/.NET/Python programming, NodeJS code is simple to set up and maintain. It doesn’t necessitate any complicated setup setups. Node.js allows rapid API development and setup with frameworks like Express, Sail, and Hapi.

Apps with a Business Focus

Microservice architecture enhances collaboration and understanding across teams because it is broken down into smaller components throughout the business domain. Adding new features to microservices is also a lot easier for developers than adding new features to old monolithic development models.

Microservices architecture best practices

From the time you investigate microservice architecture for your next project to the end of application deployment, here are best practices organized into categories that mirror the growth of major software development lifecycle (SDLC) phases.

1. For planning and organizing-

  • Assess whether the microservices architecture is a good fit for your needs: Adopting a microservices architecture only because the big names are doing it is not a good reason to do so. You should examine your needs to determine where you might divide them into useful functions.
  • Get everyone on board with the idea: Transitioning from a monolithic architecture to microservices is a long and arduous process that affects more than just the development team. As a result, form teams based on microservices. Teams should treat each microservice as though it were a distinct application.

2. When designing the microservice-

  • Make the following distinctions between your microservices and your business functions and services: You’ll be able to avoid creating microservices that are either too big or too little if you do this.
  • Create loosely linked services with excellent cohesion that cover a single constrained environment: It assures that a microservice is only used in a single context, resulting in Domain-Driven Design (DDD).
  • To communicate between services: You have to use APIs and events instead of calling each other directly. Instead, create an API gateway that manages authentication, requests, and answers for the services, as well as throttling. You may quickly redirect traffic from the API gateway to the updated version of your service if you have an API gateway in place.
  • Consider the potential for security flaws in a microservice design.

3. When it comes to creating the microservice architecture-

  • Each service should have its version control strategy: For simplicity of access provisioning and clean version control logs, each service should have its repository.
  • The development environment should be the same on all machines: Set up your service’s development environment as virtual machines to allow developers to swiftly adjust the framework and get started.
  • Backward compatibility should be included for the service endpoints you’re exposing: Backward compatibility is also possible thanks to the API calls made in response to each user query. This allows your company to develop production-ready applications more quickly.

4. For the storage and administration of data-

  • Each microservice should have its database or data store: Choose a database that meets your microservice’s requirements, tailor the architecture and storage to the data it will hold, and use it only for that microservice.

5. For deployment and hosting-

  • Separately deploy your microservices: This saves time when communicating with numerous teams during routine maintenance or upgrades projects.
  • Containerize your microservices: Microservices and containers frequently go hand in hand. Individual services can be deployed and managed individually with containerized microservices.
  • Make your microservices a separate build and automate the deployment process.

6. For operations and maintenance-

  • Use a centralized system for logging and monitoring: A centralized logging system ensures that all microservices send logs in the same format while saving logs separately for each of them.

The Key Takeaway Is That: Microservices And NodeJS Go Hand In Hand
