Defenders - caller based EC2 security with CDK

Thumbnail
Defenders: Caller based EC2 security The risk with security credentials is that they get exposed an are beeing used elsewhere. What if we could prevent that the are beeing used elsewhere. The idea from the article of William Bengston from netflix was: Dynamically locking credentials to the environment. This implementation of this idea is much more simple with the cdk. So, let’s defend ourselves! Our story here is the battle of the defenders ™.

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

Getting around circular CloudFormation Dependencies: S3-Event-Lambda-Role

Thumbnail

Getting around circular CloudFormation dependencies

Several posts complain about the inability of CloudFormation to apply a Lambda event function to an S3 Bucket with an dynamically generated name.

The standard UseCase is an S3 Bucket with a Lambda event notification. In this special case the Bucket has a dynamically generated name. This cannot be done by pure CloudFormation!

How to work around this circular depency? Let me show you an easy way:

The serverless kingslayer? - Migration from serverless to CDK

The serverless kingslayer? - Migration from serverless to CDK Last day I have been at a customer and suggested using the CDK for Infrastructure as code. He responded with a huge yes. He has worked his way through the CDK Intro Workshop aws-cdk-examples/typescript at master · aws-samples/aws-cdk-examples · GitHub and wanted to use it. Then we discussed a lambda function. The customer was using the serverless framework - like most of the people.

CDK - under Construction - should we use it for the next project?

Thumbnail

Should we use CDK for the next project?

The AWS CDK (Cloud Development Kit) is great - and still in beta - so the question for the next project would be:

Should we use cdk or not?

This post will look at the state of the cdk. Also we provide our CDK Templates updated to the CDK Version 0.38 if you want to get started.
