Enforcing encryption standards on S3-objects

Thumbnail
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.

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.

The case of the missing bucket notifications

Thumbnail
The case of the missing bucket notifications A few days ago I was trying to do something quite simple. I wanted to send S3 Put-Events to multiple Lambda functions for processing. This is a pretty common pattern. To implement it you have to use an architecture such as the one you can see in the title image above. This is because S3 has a limit on the event handlers (notification targets) per event type of exactly one.

More Tools - CDK Examples

We need more CDK examples

In this github repo we focus on examples for every day work. While there are some nice examples for the fancy stuff like fargate, ecs and so on in aws-cdk-examples/typescript at master · aws-samples/aws-cdk-examples · GitHub, i felt that basic examples where missing.

So we created GitHub - tecracer/cdk-templates: Templates for aws cdk
