How FinOps Drives Value for Every Engineering Dollar

Duolingo’s FinOps crew didn’t just track cloud costs—they wired up sharp, automated observability across 100+ microservices. Real-time alerts now catch AI and infra spend spikes before they torch the budget. They sliced TTS costs by 40% with in-memory caching. Dumped pricey CloudWatch metrics for P..

Top 30 Argo CD Anti-Patterns to Avoid When Adopting Gitops

A teardown of Argo CD anti-patterns calls out 28 common misfires—stuff like skipping Git for Application CRDs or stuffing Helm/Kustomize config right into Argo CD manifests. Yikes. It pushes for a cleaner setup: use **ApplicationSets** instead of rolling your own YAML, turn on **auto-sync/self-heal..

Introducing DigitalOcean Organizations, a new and comprehensive account layer

DigitalOcean just dropped **Organizations**—a real upgrade for anyone juggling multiple Teams. Think one top-level account to rule them all: centralized user control, one invoice to track, and org-wide settings for taxes, credits, and permissions...

What are Error Budgets? A Guide to Managing Reliability

OneUptime shows how to put **error budgets** to work—keeping feature velocity in check without tanking reliability. The goal: ship fast, stay within SLOs. They do it by tracking **burn rates**, syncing across teams, and tuning SLOs to match how users actually use the product. Less guesswork, more s..

Intelligent Kubernetes Load Balancing at Databricks

Databricks replaced default Kubernetes load balancing for a **proxyless, client-side gRPC setup**, wired up through a custom control plane. No more **CoreDNS**. No more **kube-proxy**. Clients now get live endpoint discovery through **xDS**, plus smarter routing tricks like **Power of Two Choices** ..

v1.34: Pod Level Resources Graduated to Beta

Kubernetes v1.34 bumps **Pod Level Resources** to Beta—and flips them on by default. Now you can set CPU, memory, and hugepages limits for the whole Pod, not just per container. That means smoother scheduling, stricter resource caps, and less sidecar thrashing. **Why it matters:** This shifts Kuber..

Top 10 Kubernetes Deployment Errors: Causes and Fixes (And Tips)

Misconfigured YAML. Broken image refs. Botched resource settings. Most Kubernetes deploys don't fail mysteriously—they fail predictably. This guide breaks down the top 10 culprits: things like `CrashLoopBackOff`, bad image pulls, and `OOMKills`. More importantly, it shows how to dodge them with bet..

Why Rancher's Founders Pivoted From Kubernetes to Agentic AI

Obot.ai just dropped out of stealth with $35M in seed and a big swing: it’s building a control plane for agentic AI, anchored on the now-standard **Model Context Protocol (MCP)**. Its **MCP Gateway** handles registry, secure proxying, RBAC, and observability for MCP servers. Think API gateway, but ..

KubeCon + CloudNativeCon North America 2025 Co-Located Event Deep Dive: Kubernetes on Edge Day

The inaugural Edge Day launched as a co-located event at KubeCon + CloudNativeCon EU in 2022, focusing on edge computing and the evolution from centralized data centers to the network edge. The event brings together academic research, enterprise use cases, and insights from the Kubernetes community...

KubeCon + CloudNativeCon North America 2025 Co-Located Event Deep Dive: Kubernetes on Edge Day
Pelagia is a Kubernetes controller that provides all-in-one management for Ceph clusters installed by Rook. It delivers two main features:

Aggregates all Rook Custom Resources (CRs) into a single CephDeployment resource, simplifying the management of Ceph clusters.
Provides automated lifecycle management (LCM) of Rook Ceph OSD nodes for bare-metal clusters. Automated LCM is managed by the special CephOsdRemoveTask resource.

It is designed to simplify the management of Ceph clusters in Kubernetes installed by Rook.

Being solid Rook users, we had dozens of Rook CRs to manage. Thus, one day we decided to create a single resource that would aggregate all Rook CRs and deliver a smoother LCM experience. This is how Pelagia was born.

It supports almost all Rook CRs API, including CephCluster, CephBlockPool, CephFilesystem, CephObjectStore, and others, aggregating them into a single specification. We continuously work on improving Pelagia's API, adding new features, and enhancing existing ones.

Pelagia collects Ceph cluster state and all Rook CRs statuses into single CephDeploymentHealth CR. This resource highlights of Ceph cluster and Rook APIs issues, if any.

Another important thing we implemented in Pelagia is the automated lifecycle management of Rook Ceph OSD nodes for bare-metal clusters. This feature is delivered by the CephOsdRemoveTask resource, which automates the process of removing OSD disks and nodes from the cluster. We are using this feature in our everyday day-2 operations routine.
