Create a serverless URL shortener in AWS with Terraform

Learn how to create a serverless URL shortener in AWS using Terraform. The project architecture consists of API Gateway, Lambda Function, DynamoDB, and DAX (DynamoDB Accelerator). The application allows users to input a URL and receive a redirect URL with a short code attached. The infrastructure is managed using Terraform, making it easier to provision and modify services. The URL shortening functionality is implemented through a Lambda function that saves the URL in DynamoDB and generates a short URL code. When a user calls the short URL, the application checks the cache for the corresponding record and redirects the user to the original URL.
