Setup Python Lambda with Application Composer (AWS SAM)This guide outlines the initial steps for creating your first serverless API project utilizing AWS Lambda with Python and DynamoDB, leveraging Infrastructure as Code (IaC) through the AWS Serverless Application Model (SAM). Utilizing AWS SAM's Application Composer, you'll experience a streamlined, drag-and-drop interface to visually assemble your application's components. This approach simplifies the deployment and management of serverless architectures, enabling rapid development and integration of API Gateway, Lambda functions, and DynamoDB in your cloud-based applications.

Setup Lambda function for Login
Setup a simple way to test authenticated, this API endpoint will return a JWT Token and refresh token. This is something you can continue to build on if you decide to use a custom function for authenticating users. Firebase has a great SDK for most clients that takes cares of refresh token, hence my recommendation would be to use Firebase SDK on the client side (Web/Mobile) and get the Token generated from the SDK in your production app.

How long do I have access to the course materials?
You can view and review the lecture materials indefinitely, like an on-demand channel.
Can I take my courses with me wherever I go?
Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don't have an internet connection, some instructors also let their students download course lectures. That's up to the instructor though, so make sure you get on their good side!
