In this video, we dive deep into AWS Lambda Layers and understand how they help you write cleaner, reusable, and more efficient serverless applications.
If you are working with AWS Lambda functions, managing dependencies can become messy and increase deployment size. That’s where Lambda Layers come into play. In this demo, I will show you how to create, attach, and use Lambda Layers step-by-step.
You will learn:
What AWS Lambda Layers are and why they are important
How to package external libraries (like pandas, numpy, etc.) into a layer
Step-by-step demo of creating a Lambda Layer
How to attach a layer to a Lambda function
This video is perfect for beginners as well as experienced developers who want to optimize their serverless architecture and follow best practices.
By the end of this video, you’ll be able to reduce duplication across Lambda functions and improve maintainability using layers.
