Most engineers know pods, Deployments, and Services well enough to ship every day. The architecture beneath those abstractions gets less attention, until you’re negotiating an EKS contract or debugging a scheduler backlog at 2 a.m. This guide walks through how the control plane, data plane, etcd, kube-scheduler, kubelet, and CNI plugins fit together as a system, what breaks when they don’t, and what managed Kubernetes actually takes off your plate.

In November we shipped an MCP server at https://mcp.cpln.io/mcp. Connect any MCP-aware AI agent — Claude, Cursor, Codex, Gemini — and it can operate the full Control Plane platform from natural-language prompts. We’ve followed that up with releasing an AI Plugin that includes the MCP server along with skills, agents, slash commands, and guardrails. This
84% of companies struggle with cloud spend. Here are the 10 best FinOps tools in 2026 to prevent waste, with pricing, actionability scores, and reviews.
Master the 2026 multi-cloud operating model. Bridge the complexity gap to enable autonomous AIOps, edge convergence, and shift-left security.
In 2026, outages are certain. Master Resilience Velocity to survive the Complexity Horizon and turn a 15-hour AWS outage into a non-event.
Reactive cloud cost-cutting leads to “Infrastructure Atrophy,” sacrificing performance and reliability for short-term savings. The 2026 solution is cloud cost optimization, leveraging scale-to-zero and pay-per-use architectures to eliminate idle waste without compromising product health.
Eliminate the “idle tax” to reclaim 40% of your cloud spend and secure CSRD compliance.
Senior engineers are quitting because infrastructure plumbing has replaced actual building. This analysis explains why cloud abstraction is the ultimate retention lever for 2026.
Stop paying for undead infrastructure that eats 30% of your cloud budget. Learn how to identify these hidden monsters and reinvest that waste back into innovation.
Kubernetes 1.35 introduces in-place vertical scaling—but adopting it safely is harder than it looks.
Cloud automation streamlines processes, enabling quick and reliable application deployment while reducing costs. It fortifies security, ensures compliance, and improves disaster recovery. Learn more with Control Plane.
MLOps tools are crucial for simplifying the development and management of machine learning models. They automate tasks and ensure reproducibility, helping organizations maximize the value of their ML investments.
