Digest #146: AWS OpenSearch Joins Linux Foundation, EKS Automation, Optimizing Terraform, and IBM Acquires Kubecost
AWS OpenSearch joins Linux Foundation, face recognition for infra automation, and mastering Terraform efficiency. Plus, Dockerizing Go APIs, optimizing cloud migrations, and the latest projects.
Welcome to this week’s edition of the DevOps Bulletin!
In this issue, we’re highlighting key updates like AWS OpenSearch joining the Linux Foundation and IBM's acquisition of Kubecost. We also explore Uber's journey to a data lake cloud migration and ask if SRE has lost its meaning in modern DevOps. Plus, catch a different take on Amazon’s new return-to-office policy.
On the tutorial side, we've got a range of guides: from mastering Kubernetes contexts and automating EKS access, to building a face recognition-powered infrastructure with Terraform. Learn how to optimize Terraform, Dockerize a Golang API with MySQL, and simplify Azure deployments with Bicep. There’s also a guide for installing Arch Linux on laptops, and tips for integrating OpenTelemetry with just 200 lines of code.
Don't miss this week’s featured open-source projects: from a Git visualizer and shell one-liner beautifier, to a Postgres TUI and safe Kubernetes management tool.
