#87: Testing AWS Infrastructure

This week, we'll take a look at some common Git commands that you probably don't need. Next, we'll dive into the world of Kubernetes with a compilation of failure stories. We'll also explore some practical tips and tricks to help you preview your Argo CD changes, upgrade your Kubernetes cluster, and test your AWS infrastructure changes with Localstack and Terraform. Plus, learn how to automate these processes within your CI/CD pipeline for even greater efficiency.

We'll also cover some important best practices for choosing a Postgres primary key, migrating to the cloud while staying cost-effective, and deploying any frontend web to the cloud with minimal configuration.

We'll also show you how to analyze your Lambda logstream, learn Rust with a hands-on book and how to implement DORA metrics in your organization to optimize your DevOps performance.

That's just the tip of the iceberg! So make sure to read through this issue thoroughly and don't miss out on any valuable insights and tips to improve your DevOps workflows.

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.
