C# and AWS Lambdas, Part 5 – Updating the Zip in S3 and Updating the Running Lambda, with Pulumi IaC

This post pulls together a few threads I’ve been working on - the creation of Lambda to run .NET, storing the zip in S3, and updating the .NET Lambda when the zip in S3 is updated. This one took quite a while to put together - the permissions, roles, and policies were not obvious and I hope it will be of help to you.

C# and AWS Lambdas, Part 4 – Storing the Zip in S3, Setup with Pulumi IaC

In the previous post, I showed how to use Pulumi to create a Lambda, API gateway and upload a zip of Web API application directly to the Lambda.

In the post I’m going to use S3 to store the zip of a simple .NET application (not a Web API app) and point the Lambda at it, bringing all the resources up using Pulumi. One drawback of using S3 to store the zip for a Lambda is that when you update the zip in S3, AWS doesn’t deploy the new zip to the Lambda, but I will show a way of handling that in the next blog post.

C# and AWS Lambdas, Part 3 – Pulumi IaC for Web API and an API Gateway

In this the third in a series of posts on using .NET in AWS Lambdas I build on the previous post where I connected a Http Gateway to a Lambda running a Web API application. In that post I built the infrastructure by hand, i.e. via the GUI, pointing and clicking.

In this post, I will show how to build everything with Pulumi.

C# and AWS Lambdas, Part 2 - Web API and an API Gateway

In the previous post I created a Lambda that executed a C# console application. In this post, I walk through creating a .NET Core 3.1 Web API application inside a Lambda and making it reachable from the web, just like a normal Web API application.

C# and AWS Lambdas, Part 1 - Hello World

First in a series of posts on using .NET with AWS Lambdas. It will start with the simplest example that converts a lowercase string to an uppercase string, but by the end, you will be running a .NET Web API powered by Lambda, fronted by an API gateway where all the infrastructure is set up by Pulumi - this will take a few posts over the next while.
