AWS Lambda is a type of serverless computing service that eliminates the need for developers to set up or manage servers to run their code. It is highly scalable and cost-effective, making it a popular choice for developing applications that demand dynamic computing resources. Developers who want to understand AWS Lambda will like its flexibility and ability to integrate with other Amazon services.
In this Cloud Lab, you’ll create a Lambda function using AWS Console and configure its runtime, environment, and execution role. Next, you’ll generate a Function URL to invoke the function through a web browser, the AWS console, curl commands, and the Boto3 SDK. You’ll then create an S3 bucket with “input” and “output” folders and configure an event trigger that automatically invokes Lambda whenever a file is uploaded. The function will process the file and store the transformed output in the designated folder. Additionally, you’ll explore Lambda versioning and aliasing to manage the Lambda function. You’ll create multiple Lambda versions and assign an alias to simplify deployments. Instead of modifying application references, you’ll update the alias to a new version, ensuring a smooth transition.
By the end of this Cloud Lab, you’ll gain practical knowledge of AWS Lambda, S3 event triggers, and version control, allowing you to build scalable, event-driven applications efficiently.
The following is the high-level architecture diagram of the infrastructure you’ll create in this Cloud Lab:
