Spice up your Cloudformation Development life

Thumbnail

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.

So it’s better to have a super secure set-up right from the beginning.

S3 Cross Account Adventures

Thumbnail
In the process of building a data lake in a multi-account environment, we encountered a problem that didn’t fit into our existing mental model of how S3 and S3 cross account permissions work. Chances are that the behavior might surprise you as well. We had planned to build a data storage platform that’s similar to a data lake in a multi-account environment. Essentially, this means that we were separating the data from the transformation and input/output logic.
