Utilities you'll care about

All these are already installed on epyc.

• kafkacat (conda install -c conda-forge kafkacat)

• kt (grab it from https://github.com/fgeller/kt/releases)

• kafka-* (come with kafka, if you yum install if from Confluent's repo, or via Docker if you're so inclined). Warning -- JVM based and dreadfully slow.

• jq (conda install -c conda-forge jq or use your favorite package manager)

I get asked regularly for good resources on AWS security. This gist collects some of these resources (docs, blogs, talks, open source tools, etc.). Feel free to suggest and contribute.
