Lambda Best Practices?

Question

Customer has a question about using Lambda:

*"Do you have any best practice/recommendations/online material for using Lambda and specifically how one can manage it through their landscape. At the moment, we manually turn the Lambda functions off before a release and then back on manually."*

Is there a recommendation on how they can optimize this?

Accepted Answer

Hello,

We have best practices documented [here](https://docs.aws.amazon.com/lambda/latest/dg/best-practices.html)

On top of that I would recommend looking at the [Well Architected Serverless Lens](https://docs.aws.amazon.com/wellarchitected/latest/serverless-applications-lens/welcome.html), which has a *lot* of recommendations for running production grade serverless apps.

There are many services, tools, and frameworks that can help you deploy your apps / functions. To start off with I recommend taking a look at features such as:

- [Stages for API Gateway](https://docs.aws.amazon.com/apigateway/latest/developerguide/canary-release.html)
- [Versions and Aliases for Lambda](https://docs.aws.amazon.com/lambda/latest/dg/configuration-versions.html)
- [Using SAM and Safe Deployments](https://aws.amazon.com/blogs/compute/implementing-safe-aws-lambda-deployments-with-aws-codedeploy/)
- [AWS Step Functions: Workflows for development and testing](https://www.youtube.com/watch?v=X79vSGi3qGU&ab_channel=ServerlessLand)
- [Serverless CICD reference deployment](https://aws.amazon.com/quickstart/architecture/serverless-cicd-for-enterprise/)

[ServerlessLand](https://serverlessland.com/) also has a ton of resources.
