Summary
The first section explained how AWS Lambda functions are created, deployed, and configured using the AWS Management Console and SDKs. We outlined how to package function logic, define runtime settings, and manage permissions to ensure secure and efficient execution. Practical examples, such as creating a URL shortener, illustrated how serverless code can be deployed to respond to specific tasks without provisioning infrastructure.
We then covered how to connect Lambda functions with event sources such as S3 and API Gateway. These integrations enable event-driven workflows, where functions are automatically triggered by changes such as file uploads or incoming HTTP requests. This approach supports efficient and scalable architectures by reducing the need for always-on resources while maintaining responsiveness to events.
The chapter concluded by demonstrating how AWS Lambda can interact with other AWS services, such as Amazon SNS, DynamoDB, and SQS. These services allow...
