#microservices learning path

Microservices is an engineering approach, which is based on building an app as a collection of small services. The main advantage is the maintainability of code. It is a surrogate method to a serverless approach. Microservices certainly bring more business value but at the same time, it requires a stable and secure technology such as Node.js to develop apps without complexities. Microservices developed in Node.js is most appropriate for enterprise-level projects for improving maintainability.

Microservices are a single self-functional system which, along with other units, form a complex system. Each small unit of the system is a fully functional, scalable, and deployable system. Each unit can be written in different programming languages and tested separately without causing an impact on other parts of the system. Microservices are the big block made up of smaller sub-blocks (Services), with each sub-block being an independent operating unit. If any of the unit (services) goes wrong, it will not take long to replace that service, which in turn reduces the risk of development and the costs involved in the operation of the infrastructure. This architecture is widely used by world-famous organizations including Uber, Netflix, Amazon, eBay, Groupon, and many more. Microservices are not coupled with any technology say Java or Node. You are free to choose any technology to build systems with Microservices style.

Microservices

They  are small and specific to business requirement.

Loosely coupled and can be easily developed and deployed.

Development can be done using different technologies.

Microservices can be built with new technology stack enabling faster development cycles.

Can be easily scaled on demand.

Compared to monolithic architecture, microservices are hands down more beneficial. You don’t need to stuff all software components and services in one big container and pack them tightly.

Building JavaScript applications on microservices help you focus on developing monofunctional modules with clearly defined operations and precise interfaces. The application development process becomes more agile, and the challenges of continuous testing are mitigated. When you build applications on a monolithic architecture, the entire application needs to be deployed with every update.

On the other hand, microservices have no dependency on the type of framework, technique, or programming language being used to build them. Your ability to release REST-ful APIs for communication and other services is the only requisite for microservice architecture.

Note: Different enterprises like Go Daddy, Paypal, Netflix have used this strategy to create scalable applications.

Microservices certainly bring more business value but at the same time, it requires a stable and secure technology such as Node.js to develop apps without complexities. Microservices developed in Node.js is most appropriate for enterprise-level projects for improving maintainability.

Pre-requisites:

Working knowledge of JavaScript and Node.js

Some exposure to the HTTP protocol

You should've at least heard of Node.js

Node.js and npm (The Node.js installation will also install npm.)

Before we discuss microservice we have to know about the traditional method used before microservices. In monolithic engineering, they are built as one large system and are usually one code-base. A monolith is often deployed all at once, both front and end code together, regardless of what was changed. Microservices architecture is where an app is built as a suite of small services, each with its own code-base.

Monolithic

Understanding a huge code base becomes difficult, especially for new developers.

Large code files make the development environment slow, like IDE.

Changing technology or language becomes complicated as the code base is tightly coupled.

CI/CD becomes challenging and time-consuming and needs a dedicated team to manage it.

Microservices

They are small and specific to business requirement.

Loosely coupled and can be easily developed and deployed.

Development can be done using different technologies.

Microservices can be built with new technology stack enabling faster development cycles.

Can be easily scaled on demand.

Compared to monolithic architecture, microservices are hands down more beneficial. You don’t need to stuff all software components and services in one big container and pack them tightly.

With microservices, you can build an app with:

Greater flexibility

High scalability

Continuous development

Systematic data organization

Time optimization

Reliability

Building JavaScript applications on microservices help you focus on developing monofunctional modules with clearly defined operations and precise interfaces. The application development process becomes more agile, and the challenges of continuous testing are mitigated.

 Why Microservices with Node.js?

A rich database of multiple JavaScript modules provided by Node.js simplifies the application development significantly. Software architects prefer Node.js as a technology partner for developing JSON API-based applications, I/O bound applications, data streaming applications, single-page applications, and data-intensive real-time applications. Some of the benefits are listed below.

Productivity: Node.js uses NPM (node package manager) which comes up with tons of ready to use modules that speed up the development process. Node.js uses javascript as interface language so that the same language can be used for back end and front end. This saves lots of development time.

Performance: Node.js event-driven I/O model along with microservices strategy which can handle an extreme amount of load with the lesser response time.

Friendly to Developer: Node.js has vast community support and is backed by millions of developers across the globe. The Node package manager (NPM) contains more than 4 million ready to use modules which serve as a heaven for developers. Node.js enables faster development of applications that are easily scalable, thereby making the developer happy throughout the application development life cycle.

Note: Different enterprises like Go Daddy, Paypal, Netflix have used this strategy to create scalable applications.
