While Infrastructure-as-Code slowly becomes omnipresent, many of the communicated advantages of the approach stay mostly unrealized. Sure, code style checks (linting) and even automated documentation get more common every month. But one of the cornerstones often gets ignore: testing. Let’s see which types of code testing are available and how to do it without writing too much code. The promise of the Infrastructure-as-Code (short: IaC) movement is to handle infrastructure just as if it was a program.

The newly introduced ECS Anywhere feature lets us use our existing resources as Compute Power in Amazon ECS. Let’s talk about some basics and see how ECS Anywhere can be set up in Terraform!

In some rare cases it is important to know on which Operating System Terraform is being executed. Since there is (yet) no functionality that solves this by Terraform this hack can help in these situations.

Yoni: Oftentimes, when we think about protecting resources in the cloud, we immediately think about the typical ways in - via public-facing applications or abuse of credentials. In this talk, we will look at one additional way: through the work unit parameters of a service. During the development of Indeni’s Cloudrail SaaS product, Yoni was responsible for trying to find ways to hack into the service. One of the ways he found, raises questions about how secure ECS workloads really are.

Consistent Style Across Editors Sometimes, common themes occur if working on a project with multiple people and different development environments. One of the unexpected, time-consuming problems is related to editor configurations. But it is pretty easy to unify things, if you know where to look…

Pure CloudFormation coding only with vi can be hard work. But since CloudFormation still is the lingua franca of AWS infrastructure as code, the ecosystem keeps evolving. Even if you only use it indirectly, there are some tools to spice up your development. Hot diagrams, more aroma with compliance checks or bittersweet automated testing. Ready to taste it? Here we go.

AWS Setup: Secure Identity Foundation with Terraform When it comes to access management in AWS, often I see a basic setup, with Users in IAM, as described here. Clearly, most people focus on building actual running applications, at first. After the first running POCs, the next migrations are on the road map; your architecture evolves, but the initial IAM setup stays. So it’s better to have a super secure set-up right from the beginning.

CloudFormation does not cover all AWS Resource types. Terraform does a better job in covering resource types just in time. So if you want to use a resource type which CloudFormation does not support yet, but you want to use CloudFormation, you have to build a Custom Resource with an own Lambda Function. CDK to the rescue: use AwsCustomResource.
