My first AWS Lambda function

Over the past few months I’ve become a bit more familiar with various Amazon Web Services (AWS) offerings, incuding EC2, S3, and Batch. I’ve heard about AWS Lambda, but never had a chance to try it out. So I decided to work through this tutorial to create my first Lambda function.

AWS Lambda is a serverless computing service that lets you run code without provisioning or managing servers. You pay only for the compute time you consume - there is no charge when your code is not running. With Lambda, you can run code for virtually any type of application or backend service - all with zero administration. Just upload your code and Lambda takes care of everything required to run and scale your code with high availability.

In the tutorial, the user creates a Lambda function that is triggered adding an object to an S3 bucket, and a Python function outputs the object type to CloudWatch logs. The tutorial is very well written and easy to follow:

As with any new skill, you have to learn to walk before you run. I’m hoping to use Lambda for my own projects very soon. Stay tuned for more updates!
