Kubernetes - The Better OpenStack?
summary
Claim: Kubernetes is already cannibalizing Cloud Foundry and could replace OpenStack as the de facto infrastructure API. Evidence: anynines moves from Chef to BOSH and OpenStack, operates customers with ~3,000 VMs and data services, and runs tests showing co‑located containers introduce unpredictable disk and network performance for databases (noisy‑neighbor IO). Tools discussed: Kubernetes, BOSH, OpenStack, Docker, VMware Project Pacific and kops. Proposed fixes include on‑demand Kubernetes nodes or melting K8s into the hypervisor to regain VM‑level isolation.
