Digest #108: Kubernetes vs Docker Swarm ⚔️

#108: Kubernetes vs Docker Swarm
In this week's DevOps digest, I've curated a range of topics, from Terraform architecture to incident response practices.

First, we explore a sustainable architecture for Terraform and ask whether it's essential to test every line of your CDK application. We then compare CI/CD pipelines in tools like GitHub Actions, CircleCI, Jenkins, and more, and examine Netflix’s switch to GraphQL with no downtime.

We’ll see how Terragrunt keeps Terraform configs DRY and unveil the Kubernetes software release process. I also delve into the speed of third-party databases on AWS Lambda and take a closer look at DataDog's incident response.

This week's open-source projects include tools to secure data across AWS accounts, a CDK construct for website analytics, and a simple Git-based version control system.

Remember, there's plenty more in the full newsletter, so stay tuned, keep learning, and enjoy this week's digest!
