DevOps Bulletin - Digest #89: Pipeline as Code 🔥

#89: Pipeline as Code

This week, I have a lot of exciting topics for you. To start off, we cover the basics of effective dashboard design and how you can create a Grafana dashboard that will make troubleshooting incidents a breeze. If you're looking to break into the Linux industry, I'm sharing a month-long free course. We explore cloud governance using Infrastructure as Code and provide tips to eliminate Kubernetes node scaling lag.

In addition, I cover best practices for debugging and provide an extension review for AWS SSM Lambda. And why you shouldn't teach during code reviews and provide a complete guide to AWS Lambda pricing. I also have an open-source browser extension to download eBooks from AWS Resource Hub without filling out forms, as well as a learning roadmap to master Kubernetes. I also cover how Cloudflare uses Terraform to manage its infrastructure and highlight a vulnerability in AWS CloudTrail. And that's not all! I also have a book on Pipeline as Code, which covers building your CI/CD pipeline in a cloud-native world and more 🔥

I hope you enjoy this week’s newsletter! Share it with a friend or colleague if you find it helpful, drop me an email or send me a DM on Twitter about topics you’d like to hear about in future editions.

I wrote a book called Pipeline as Code which focuses on automating your development pipeline in a cloud-native, service-driven world. The book covers the use of infrastructure-as-code tools such as Packer and Terraform to create robust CI/CD pipelines for various cloud-native applications, including Kubernetes and Serverless. It also teaches how to build and deploy a Jenkins cluster from scratch on AWS, GCP, and Azure. If you are unable to purchase the book, send me a direct message on Twitter and I will provide a free eBook version 😅
Manually securing Kubernetes can leave your organization vulnerable to breaches. Armon Dadgar, CTO of HashiCorp outlines how implementing an automated zero-trust security strategy addresses common challenges users face when securing Kubernetes.
