Welcome to this week’s edition of the DevOps Bulletin!

We share surprising news on ClickHouse acquiring HyperDX, and reveal newly discovered ruby-saml vulnerabilities on GitHub. Plus, check out highlights from the latest State of FinOps 2025 report.

Our featured podcast tackles cloud networking's biggest headaches: moving from data centers to AWS, the hidden traps, unexpected wins, and security issues nobody talks about.

In our tutorials, get clear, easy-to-follow tips on zero-downtime Kubernetes deployments with AWS EKS, building reliable FinOps pipelines, and integrating Helm charts with Terraform. Plus, learn how attackers can execute code on millions of users—and how to prevent it.

We also highlight practical open-source tools, including Shef (a CLI for shell recipes), xlskubectl (Kubernetes management from spreadsheets), and XPipe, a shell-based hub for managing remote connections.

All this and more in this week’s DevOps Bulletin—don’t miss out!
