In this article you'll find out how Invoking Lambda functions locally with AWS SAM. You can invoke your function locally by using the sam local invoke command and providing its function logical ID and an event file. The sam local invoke command described in this section corresponds to the AWS CLI command aws lambda invoke.
In my D2D work as a Back-End Engineer, I am quite intensively working on AWS Serverless. Serverless is a new concept in software development.
Serverless is a way to describe the services, practices, and strategies that enable you to build more agile applications so you can innovate and respond to change faster.
AWS provides different Serverless services for different purposes and Lambda is one of them.
Lambda is one of the serverless compute services by AWS. which helps you to create applications in small pieces of functions (handler).
Writing lambdas at the beginning is a bit difficult and hassle. Since we have to know a lot about lambdas — from different configurations to SAM template.
In this article, we will create a lambda function and invoke that function using AWS SAM CLI in a local environment. We will be using everything locally. So you don’t need any AWS cloud services.
You must have installed the following tools on your machine in order to get started.
AWS KMS is a Key Management Service that let you create Cryptographic keys that you can use to encrypt and decrypt data and also other keys. You can read more about it here.
In this article, I am going to explain how to create an AWS Lambda function and then call this function from another Lambda function within the same region. This is a useful scenario in which we may need to execute a second lambda function based on the outcome of some previous logic

Serverless Express enables you to easily host Express.js APIs on AWS Lambda and AWS HTTP API. Here is how to get started and deliver a Serverless Express.js based API with a custom domain, free SSL certificate and much more!
Adding Code to AWS Lambda, Lambda Layers, and Lambda Extensions Using Docker. With Docker, we have three ways to add code to Lambda that isn’t directly part of our Lambda function. Try to AWS Lambda, Lambda Layers, and Lambda Extensions Using Docker.
