Mesh control plane vs data plane availability
WHAT IT TESTS: mesh plane separation and failure modes. OUTLINE: the control plane configures and distributes policy; the data plane is the sidecars carrying traffic with cached config, so a brief control-plane outage keeps existing traffic flowing but…
WHAT IT TESTS: understanding that the data plane keeps moving traffic when the brain is offline. ANSWER OUTLINE: the control plane computes and pushes configuration, certificates and policy to the proxies; the data plane is the fleet of sidecars that actually move requests using their last-pushed config. If the control plane is briefly down, proxies keep routing with cached config so existing traffic is unaffected, but no new config, endpoints or certs propagate. RED FLAG: claiming all traffic halts when the control plane is unavailable.
