AWS

If you are Amazon.Lambda.Templates, version 6.3.0 or earlier with .NET 7 RC 1, you may get an error when creating new project templates. Read on for a fix or a workaround.

Secrets are usually retrieved far more often than they are changed. The AWS Secrets Manager cache lets you cache secrets for a specified period, reducing the number of requests your applications need to make.

With Lambda versions and aliases you can setup A/B testing for your functions. This example uses .NET 6 and Lambda Function URLs, but the same principles apply to other languages.

This is a simple Lambda function that uses a Function URL. This blog post will be referenced in more complicated examples.

If you want to experiment with code variations for a Lambda function, try Lambda versions. In this post, you’ll see how to deploy a stable and experimental version of the same function.

You can’t yet run .NET 7 on AWS Lambda functions with the familiar managed runtime, but you can with a custom runtime. Here are the few small steps you need.

If you are using IAM auth with Lambda Function URLs, and you want to call the function using HttpClient from a .NET application, you need to sign the request. Read on to see how.

Even though Lambda functions are “serverless”, and even though there is no guarantee how long a function will remain “warm” for, you might still get good use out of a memory cache.

Here are two ways to page through files in an S3 bucket.

When a Lambda function is connected to a VPC, the function can no longer access the internet. One way to resolve this is to use a NAT gateway, read on to see how.
