A Beginner’s Guide to Serverless Computing with AWS Using Serverless Framework

Serverless computing revolutionizes the way we build and deploy applications by abstracting away the complexities of managing traditional servers and infrastructure. This paradigm shift allows developers to focus solely on writing code, which is executed in response to specific events or requests, enabling highly scalable and cost-effective applications through an event-driven architecture.

Major cloud platforms such as AWS (Amazon Web Services), Azure (Microsoft Azure), and Google Cloud provide robust serverless computing services, offering developers a versatile and scalable environment to build applications.

Introducing the Serverless Framework

The Serverless Framework, an open-source tool, empowers developers to build and deploy serverless applications seamlessly across various cloud platforms. It offers a set of tools, libraries, and best practices, making it a valuable resource for those diving into serverless development.

In this article, we’ll guide you through the process of utilizing the Serverless Framework on AWS, using Node.js for development.

Step 1: Install Node.js and npm

Begin by ensuring you have Node.js and npm (Node Package Manager) installed on your local development machine. If not, you can download them from the official website: https://nodejs.org/en/download

Step 2: Install the Serverless Framework

Open your terminal and run the following command to install the Serverless Framework globally:

npm install -g serverless

This global installation enables the use of the serverless command-line tool.

Step 3: Set Up an AWS Account

If you don’t already have an AWS account, sign up for one at AWS console. You’ll need AWS credentials to deploy serverless applications.

Step 4: Configure AWS Credentials

create IAM user and download Access key and Secrete key after that Run the following command to configure your AWS credentials

serverless config credentials --provider aws --key YOUR_AWS_ACCESS_KEY --secret YOUR_AWS_SECRET_KEY

Replace YOUR_AWS_ACCESS_KEY and YOUR_AWS_SECRET_KEY with your AWS access key and secret key. For the more information please visit : Serverless Framework AWS CLI Reference.

Step 5: Create a New Serverless Service

Create a new Serverless service using the following command:

serverless create --template aws-nodejs

For more information please visit : Serverless Framework AWS CLI Reference for Creating Services.

Step 6: Deploy Your Service

Deploy your service to AWS with the following command:

serverless deploy

I will include a link to the GitHub repository containing the sample project for your reference. I used .env file to handle env variables. Please feel free to explore the code and resources there to get a hands-on experience with the concepts discussed in this article.
