Auto Scalers – Applications can be configured to automatically scale as and when required.

You do not need to architect for these capabilities since the services running the application provide them by default

Readily Available – Serverless applications have built-in availability and fault tolerance.

Here are the major reasons why you should consider serverless applications: Initially, Serverless was started off by AWS Lambda, but over time it also includes all of the other managed AWS Services as well like database, storage, messaging and so on. For this tutorial, we will start with AWS Lambda which is the building block of any AWS-related Serverless application! In the upcoming tutorials, we will explore the other Serverless Services provided by AWS. Now, AWS provides a bunch of services like AWS Lambda, AWS API Gateways, DynamoDB, Athena, and so on that help you in building serverless applications. We will discuss this in the later section of this article. But there are a few catches to this as well. This is probably the biggest selling point of the Serverless concept. Yep, you won’t be charged anything if your application is not actually being used or invoked. This solution follows a pay-as-you-go model, meaning that you will be billed only for the time when your code is actually being used.

You no longer have to worry about the infrastructure, scaling servers, provisioning, or configuring them. This means that we have to focus only on writing the code. Serverless doesn’t actually mean that there are no servers involved, but the responsibility of managing the servers is taken up by the cloud providers, not you or your team. Many companies are already in the process or have already migrated their applications. Re-Publishing the AWS Lambda Function (via Command Line)Īs you might have noticed, the new trend is to move existing applications into Serverless Architectures.Installing the AWS Toolkit Extension for VS 2022.Access Keys and Profiles – Local AWS CLI Setup.json file that will control language features, modules, transpilation, output pathing, etc… To learn more about these configurations, check out the typescript docs. Initialize typescript in the project by running: tsc -init. With that installed globally, tsc -v should output Version 3.1.x. Install typescript globally so it can be referenced in the CLI by running npm i -g typescript. Then, navigate to hello-ts-lambda and run npm init -y to initiate a package.json file. Go to your projects folder and create a new serverless project using serverless create -template aws-nodejs -path hello-ts-lambda. Use Typescript with AWS Lambda + Serverless Project setup
