Introduction to Serverless Node

Serverless computing is becoming a hot topic. Developers using various languages want to take advantage of its features and you certainly don’t want to fall behind with the trends. So, if your weapon of choice is JavaScript then you can implement serverless in Node.js.

We have come this far from managing servers at high maintenance and infrastructure costs to deploying server-free applications. The anticipation shows the serverless architecture’s demand, growth, and reliability. And agile development, cost reduction (compared to the traditional method), and scalability are tangible benefits you can reap with serverless architecture.

Building complex and scalable applications is also possible with serverless architecture and Node.js.

What is Serverless Node & How Does it work?

Node Serverless is where Node programmers can develop and run apps without managing and setting up physical servers at the infrastructure.

 

The Node.js serverless architecture executes Node.js functions to HTTP requests or events. All the tasks Node developers create are uploaded to cloud services providers, like AWS Lambda, which is also accountable for managing servers, infrastructure, traffic load, and scalability.

 

Now let’s see the stepwise functionality of the Node Serverless working pattern:

Step 1 : Writing for Node.js functions

It is an initial step where in the Node developer writes a function to manage a specific event.

Step 2 : Upload functions on the serverless platform

Once the function is written, the developers upload it on the serverless platform.

Step 3 : Triggering of functions in response to events

On the occurrence of any event or HTTP request by a user, the serverless platform triggers the function to respond to an event or request.

Step 4 : Offers Responses

Upon triggering the specified function, it produces a response or automatically becomes an input to an event or HTTP request.

 

Should you leverage Serverless Node.js?

Yes, you must leverage serverless Node.js since it has already offered ample benefits to business owners, and there are real-life examples.

Limitless Scalability 

Running your servers out of time or high downtime would be a thing of the past with the serverless architecture. Why? Because of its nature of scaling up and down as and when required. The serverless architecture is meant to handle any traffic volume, regardless of size.

Almost Null Downtime

word for you because serverless would never face any sort of failure. And if still, any problem persists, it will be solved in time by the cloud service provider.

Upgraded Security

Since the cloud service provider manages the server-free Node.js, the entire security control is also in their hands. And be it AWS Lambda, Microsoft Azure, or Google Cloud; everyone keeps their security controls up to date.

Enter The Market Before Your Competitors

The entire focus of any Node programmer would be on writing and running code specifically, which frees them from the worry of managing servers or scalability. Hire Node.js developers to build your next application serverless at a faster rate and in minimum time.

Optimum Utilization Of Resources

With serverless Nodejs, you can utilize resources optimally because you pay for what you use. The cloud service provider manages servers, scaling when required, balancing the website/application load, etc. It also helps you save money and better leverage the available resources.

No Infrastructure Costs

Since there is no need to manage servers physically, the infrastructure cost would also be zero. The cloud service provider manages, scales, and maintains the infrastructure and servers.
