Cloud Chirp #2 🌥️ - 1/11/2023
Hello Cloud Enthusiasts,
Welcome back to the second dose of cloud knowledge! In this edition of our newsletter, we're diving into some of the latest updates and posts from various cloud providers. Whether you're an Docker aficionado, an Cloudflare enthusiast, or a Kubernetes guru, we've got something for you. So, let's jump right into it:
🔗 Common Mistakes in PromQL and Kubernetes Metrics: Insights from Robusta Dev
Title: 3 Common Mistakes with PromQL and Kubernetes Metrics – Oct. 10, 2023
Description: Millions of developers utilize PromQL queries and Grafana dashboards for Kubernetes, relying on the same underlying metrics from node-exporter, kubelet, and kube-state-metrics. Unfortunately, common pitfalls often go unnoticed. In this post, Robusta Dev outlines a seemingly straightforward Prometheus query for Kubernetes memory usage and uncover and address mistakes related to duplicate series, grouping/sum errors, and unexpected cardinality, emphasizing the importance of understanding and validating labels for accurate metrics.

🔗 Kubernetes Ingress2gateway Release
Title: Introducing ingress2gateway; Simplifying Upgrades to Gateway API – Oct. 25, 2023
Description: In the dynamic world of Kubernetes, network management is crucial as the proliferation of applications in Kubernetes clusters raises concerns about efficient service exposure to clients. The Ingress API, a widely used solution for external service access, enables routing external traffic to cluster applications. However, it has limitations, including constraints on supporting advanced HTTP proxy features, a flawed permission model, and a lack of support for diverse protocols, making it less suitable for non-HTTP workloads in increasingly complex Kubernetes environments. The Gateway API comes to the rescue, and the best part is that you can bid farewell to migration worries, as ingress2gateway takes care of all the heavy lifting for you!

🔗 Enhancing Internet Privacy with Cloudflare ECH
Title: Encrypted Client Hello - the last puzzle piece to privacy – Oct. 29, 2023
Description: Cloudflare is pleased to introduce Encrypted Client Hello (ECH), a novel standard aimed at enhancing online privacy. ECH, succeeding ESNI, conceals the Server Name Indication (SNI) during TLS handshakes, making it impossible for anyone, except the user, Cloudflare, and the website owner, to discern which site is being visited. ECH, together with DNS over HTTPS (DoH) and Oblivious DNS over HTTPS, marks the final step in securing internet privacy, ensuring that intermediaries cannot track users' online activities, and it is already available on all Cloudflare plans.
