Understanding AWS Lambda and API Gateway

Understanding AWS Lambda and API Gateway
Before we jump into free trial options, let's briefly understand what AWS Lambda and API Gateway are:

AWS Lambda: AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers. It's ideal for executing code in response to events, such as changes to data in an Amazon S3 bucket or updates to a DynamoDB table. You can use Lambda to build serverless applications, automate tasks, or create custom backends for web and mobile apps.

API Gateway: AWS API Gateway is a managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at any scale. It acts as a front door for applications to access data, business logic, or functionality from your back-end services, such as Lambda functions.

AWS Free Tier
AWS offers a Free Tier that allows new customers to get started with a range of AWS services, including AWS Lambda and API Gateway, at no cost for a limited time. The AWS Free Tier is designed to give you hands-on experience with these services, but it's essential to be aware of the specific terms and limitations. Here's how the Free Tier works for AWS Lambda and API Gateway:

AWS Lambda Free Tier
With AWS Lambda, the Free Tier includes:

1 million free requests per month: You can run code in response to events, such as API Gateway requests or S3 object uploads, up to 1 million times per month for free.

400,000 GB-seconds of compute time per month: The Free Tier covers compute time, measured in GB-seconds, to run your code.

Provisioned concurrency: You get 3.2 million seconds of provisioned concurrency per month, allowing for better control over function scaling.

API Gateway Free Tier
For AWS API Gateway, the Free Tier covers:

1 million API calls per month: You can create, publish, and maintain APIs that receive up to 1 million API calls per month for free during the first 12 months.

Unlimited data transfer: The Free Tier offers unlimited data transfer out to the internet, making it suitable for serving APIs to a wide user base.
