Serverless infrastructure project built as part of an AWS DevOps course, demonstrating end-to-end Lambda deployment using CloudFormation and the AWS CLI.

What It Does

• Creates an IAM Role with permissions for Lambda (receive, delete, getQueueAttributes)
• Packages and deploys a Lambda function via CLI using a .zip file (no console)
• Provisions an SQS Queue and configures Lambda event source mapping
• Sets up CloudWatch Logs for function monitoring and observability

AWS Services Used

• AWS Lambda
• AWS CloudFormation
• Amazon SQS (Simple Queue Service)
• IAM Roles & Policies
• Amazon CloudWatch Logs
• AWS CLI

Key Steps Covered

1. Create IAM Role and capture ARN
2. Package function code into .zip
3. Deploy Lambda via CLI (aws lambda create-function)
4. Create SQS Queue and link as event source
5. Verify with event source mapping list and CloudWatch logs

Skills Demonstrated

• Infrastructure as Code (IaC) with CloudFormation
• Serverless architecture and event-driven design
• AWS CLI for automated deployments
• IAM permissions and least-privilege access
• Monitoring with CloudWatch
