You upload a function, AWS handles scaling, patching, and availability, and you pay only for the milliseconds your code runs. Here&#8217;s how to build your first serverless function.<\/p>\n<p>Everything starts in the AWS Console: create a function, pick a runtime, paste your code, and attach a trigger. No EC2 instances, no containers to manage.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/sumberlaba.com\/wp-content\/uploads\/2026\/09\/article-1790722826350.jpg\" alt=\"Article illustration\" style=\"display:block;margin:20px auto;max-width:100%;height:auto;border-radius:8px;\" \/><\/p>\n<h2>1. Create Your First Function<\/h2>\n<p>Open the Lambda console, click <em>Create function<\/em>, and choose &#8220;Author from scratch.&#8221; Select a runtime, name it, and let AWS create an execution role with basic permissions. A starter handler appears automatically.<\/p>\n<h2>2. Understand the Handler<\/h2>\n<p>The handler is your entry point. It receives an event object and returns a response:<\/p>\n<ul>\n<li><strong>event<\/strong> \u2013 input data from the trigger, like an HTTP request or file upload<\/li>\n<li><strong>context<\/strong> \u2013 runtime details such as request ID and timeout<\/li>\n<li><strong>return value<\/strong> \u2013 what your caller receives back<\/li>\n<\/ul>\n<h2>3. Connect a Trigger<\/h2>\n<p>Functions need something to invoke them. Add API Gateway for REST endpoints, S3 for file processing, or EventBridge for scheduled jobs. Lambda receives each event automatically.<\/p>\n<h2>4. Test and Deploy<\/h2>\n<p>Use the built-in test console with a sample event. Adjust memory and timeout \u2014 more memory also means more CPU. Then check CloudWatch Logs for output and errors.<\/p>\n<h2>Conclusion<\/h2>\n<p>Start small: one function, one trigger, one test event. Once that works, add environment variables and monitoring. The same setup scales to millions of requests without changing your workflow.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How to Use AWS Lambda for Serverless Functions: A Beginner&#8217;s Tutorial AWS Lambda runs your code without servers.
