Stop guessing capacity! - Start calculating. If you migrate an older server to the AWS Cloud using EC2 instances, the prefered way is to start with a good guess and then rightsize with CloudWatch metric data. But sometimes you’ve got no clue, where to start. And: Did you think all AWS vCPUs are created equal? No, not at all. The compute power of different instance types is - yes - different.

When building docker images with the CDK you might notice increasing build times on subsequent invocations of cdk synth. Depending on your setup, there might be a simple solution to that problem - using a .dockerignore file. In this post I’m going to briefly explain how and why that’s useful and may help you.

Encrypting objects at rest is a best practice when working with S3. Enforcing this with policies is not as trivial as you may think. There are subtle issues with default encryption, which may result in compliance risks. We’re going to investigate these issues and show you how to solve them.

In this blog post I explain to you how to handle a particular class of errors with cross stack dependencies in the CLoud Development Kit.

Going beyond the easier use case of mocking attributes and databags, we sometimes want to fake some data about the system itself.

The more complex your cookbooks, the bigger the need to supply some external information to your test machines. Passing specific attributes, values of databags or secrets for testing become necessary. We will go through these use cases and show how to mock the data in this post.

CDK is great for serverless architectures. But the deploy times even for small lambda functions is to slow. Here is a little trick which can speed up things a lot. A small caveat: It is cheating.

Generation of Infrastructure-as-Code is fun. To be the real DevOps hero, you should build a complete CI-CD pipeline. But this is a piece of work. And if you want to deploy to multiple accounts, it gets tricky. With the new CDK, builtin pipeline Construct, it’s easy - if you solve a few problems. Here is a complete walk-through.
