GPU Passthrough Works. Can You Still Move the VM?
A GPU that works on the destination has passed a performance test, not a lifecycle test. The device-access mode constrains which VM operations survive…
READ MORE →ENGINEERING NOTES FROM THE COMPLEXITY GAP.
The journey from legacy infrastructure to modern cloud-native platforms is often obstructed by marketing-driven abstraction and tool-centric noise. Most technical journals focus on the "Day-1" installation — the easy path. Rack2Cloud documents the Day-2 production reality. We analyze how systems actually behave under load, at the boundaries of integration, and within the constraints of sovereign requirements.
Our field notes serve as a deterministic guide for the architect navigating the complexity gap. We prioritize the physics of data and the logic of high availability over vendor checklists.
"In production, complexity is the default state; architecture is the only defense."
