NodeJs treading in current technology stack

The statistics says that more that 90% of tech giant and even IoT startups incorporating Node.js in their technology stack, we have no doubt its ecosystem is growing faster that past. In parallel Node.js itself is expanding its capability on all forms, processing asynchronous requests faster than before and can handle big data-sets also. In this way Node.Js foundation merging with JS foundation, brings new landscape. NASA, PayPal, Uber, Netflix, Ebay, Medium, LinkedIn, and Walmart are some actively and confidently using fortune companies, which brings more trust to Node.js.

The key points of NodeJS which makes it beneficial and dominating stack are listed below:

1. Serverless Solutions

Serverless computing is a cloud-computing execution model in which the cloud provider runs the server, and dynamically manages the allocation of machine resources. Pricing is based on the actual amount of resources consumed by an application, rather than on pre-purchased units of capacity.

Serverless architectures are application designs that incorporate third-party "Backend as a Service" (BaaS) services, and/or that include custom code run in managed, ephemeral containers on a "Functions as a Service" (FaaS) platform.

Here are a couple of ways in which choosing a serverless approach/solution could benefit your business:

• No upfront infrastructure planning – it's all provided.
• Easier pivoting – the solution dictates the usage of small reusable services, which prevents rewriting and enforces code quality.
• Increased infrastructure return rate and more precise cost projections – with serverless, you pay only for what resources you actually use.
• Variable costs and infinite scalability – there is no need to scale machines any longer, the service scales as it grows, costs are calculated on a subsecond metering basis
• Componentized development – possibility of reusing core features of applications, such as authorization or payment processing.
• Increased service stability, easier maintenance and testing – the way serverless applications are written results in simpler and more testable units.
• Shifting resources from DevOps to development.

The "Big Three" cloud vendors—Amazon, Google, and Microsoft—are heavily invested in Serverless.

2. Node.js Microservices and Orchestrators

Microservices are a single self-functional system which along with other unit forms large big system. Each small unit of the system is fully functional, scalable and deployable system. Each unit can be written in different programming language and tested separately without causing an impact on other parts of the system.

Benefits of Microservices architecture:

• The application takes lesser time to start, which increases developers productivity and speeds up deployments.
• Multiple teams can work on separate parts of an application simultaneously and Independently
• The system can be scaled easily and boost system performance.
• Each service can be deployed without affecting other services, which allows deployment of new versions of services frequently.
• Microservices are independent of each other and have a specific role. Changes made to one microservice does not affect other.
• No restriction of technology in developing any service, there by making system technologically independent.
• Application components and services can be reused by multiple applications and limit logic replication.
• Failure of a part of the system does not bring down the whole system.

3. Cloud Computing

Above solutions fall into that technology favour, but there is plenty more that hides under the term. Node.js can help you either build an entirely new product or use the existing ones to enhance your application. Cloud computing allows for the most varied service models – Platform as a Service (AWS), Software as a Service (Prisma, Google Apps), Infrastructure as a Service (Amazon EC2), Content as a Service (Contentful, Prismic) or Function as a Service (Netlify authentication).

Most cloud computing solutions benefit from all that serverless brings to the table:

1. It's relatively easy to do cost projection and anticipate its growth.
2. Scalability – virtually endless without the need to invest in hardware.
3. Security and privacy – which is usually handled by the cloud providers you choose to use for your apps.

Notable Mentions: Google Apps, Prisma, Contentful, Prismic, Storyblok, Spotify, Adobe.

4. Real time web app provisioning

Node.js performs especially well under heavy load and is hence a perfect solution for almost any real-time web project. There is a plethora of applications that require real-time communication, from chat bots, instant communication apps, tele-conferencing software, and cloud-based personal assistants, all the way to data stream processing, all of which Node will continue to shine in.

Regardless of which of the above will actually prove right, we are positive Node.js will mean cheaper, more resilient, extremely scalable, and independent services. There is no doubt that Node will also be a part of the stacks yet to emerge considering its footprint on the global developer community and the rich ecosystem it allowed for, namely the Node Package Manager.
