Lightning Talk: Unifying Hybrid Clouds: A Journey Through Multi-Control...

on YouTube ↗06m

" summary

Describes replacing a homegrown control plane with an Istio/Envoy-based multi-control-plane mesh that runs alongside the legacy system, with 100,000 sidecars and coverage across Kubernetes, bare metal, GCP and AWS. The team clones the data plane so both control planes present identical configs, enabling sidecar swap with no service code change; migration status is ~20% on the new control plane, 80% on the old, and >2,000 services in flight, with config duplication and sharding making debugging hard.
