Building Your First Lambda Function
Write and deploy a simple Lambda function, configuring its runtime, memory, and execution role.
Your First Lambda Function
Time to build your first serverless function! In this lesson, we'll write a simple AWS Lambda function that runs your code without managing servers.
We'll cover its basic structure, how to choose a runtime, and essential configurations like memory and execution roles. Get ready to deploy!
The Core: Your Lambda Handler
Every Lambda function needs a 'handler' function. This is the entry point where AWS Lambda starts executing your code. It typically receives two arguments:
event: Contains the data that triggered the invocation.context: Provides runtime information about the invocation, function, and execution environment.
Think of the handler as the 'main' method for your serverless code.
