Hey Dev Community,
Let's dive into a game-changing AWS service that might just revolutionize the way you develop serverless applications: AWS Lambda Layers! 🚀
AWS Lambda Layers allow you to manage your in-development function code independently from the unchanging code and resources that it uses. Here's why it's a game-changer:
1️⃣ Code Separation: With Lambda Layers, you can keep your function code lean and focused while offloading common libraries, dependencies, or custom runtimes to layers. This means your deployment package is smaller, making deployments faster and reducing cold start times.
2️⃣ Version Control: You can version and manage your layers separately, ensuring that your function code always relies on the specific version of the layer it needs. No more unexpected breaking changes!
3️⃣ Reusability: Layers can be shared across multiple Lambda functions, making it easy to maintain consistent libraries and configurations across your serverless applications.
4️⃣ Cost-Efficiency: Since layers are cached, you only pay for the execution time of your function code, not the layers themselves, resulting in cost savings.
5️⃣ Easier Collaboration: When working with a team, Lambda Layers make it simpler to manage shared dependencies and resources, promoting collaboration and code consistency.
6️⃣ Custom Runtimes: You can even create custom runtimes using layers, giving you more flexibility in running your code.
If you're building serverless applications on AWS, Lambda Layers are a powerful tool that can streamline your development process and enhance performance.

Just saw your awesome day by day compilation of learnings on AWS - I am going to try and browse through your posts as many as I can.
Im a self taught AWS intermediate dabbling and learning things as I need them.
I have used lamda layers and I would like to cite and example where it proved to be helpful.
I needed to do some image processing on S3 buckets, so I used sharp the image processing sdk and stored it as a lambda layer.
This helped me use it easily in the other lamda functions I created thereafter without the pain of setting up sharp again also this helped me refer to different versions of sharp just by referring to different layers.
Cheers.
