The built-in editor opens with a starter handler file.<\/li>\n<\/ul>\n<h2>Step 2: Write and Test the Handler<\/h2>\n<p>The handler is the entry point that receives an <code>event<\/code> and a <code>context<\/code> object. A minimal Python handler is: <code>def lambda_handler(event, context): return \"Hello from Lambda\"<\/code>. Keep functions focused and stateless. Use the <strong>Test<\/strong> button to invoke your function with a sample event.<\/p>\n<h2>Step 3: Add Event Sources<\/h2>\n<p>Lambda is event-driven. Common triggers include:<\/p>\n<ul>\n<li><strong>S3<\/strong>: run on file uploads or deletions.<\/li>\n<li><strong>API Gateway<\/strong>: expose your function as a REST API.<\/li>\n<li><strong>DynamoDB Streams<\/strong>: react to database changes.<\/li>\n<li><strong>EventBridge<\/strong>: schedule or integrate with other services.<\/li>\n<\/ul>\n<p>You can attach a trigger from the <strong>Function overview<\/strong> page in a few clicks.<\/p>\n<h2>Step 4: Permissions, Settings, and Monitoring<\/h2>\n<p>Lambda uses IAM roles for permissions\u2014attach the least-privilege role that allows only required actions. Tune timeout and memory under <strong>Configuration \u2192 General settings<\/strong>. Use CloudWatch logs and metrics to monitor invocations, errors, and duration.<\/p>\n<p>You now have a working serverless function.
