Lyft built Envoy and open-sourced it in 2016 to move networking concerns out of application services. What problem did that actually solve, and for which organisations does a service mesh fail to pay for itself?

A team proposes adopting a service mesh for twelve services in one language. Do you support it?

An Envoy-based mesh carries 600 services across 3000 pods. At 09:00 the mesh control plane is lost entirely and cannot be restored for 90 minutes. No application or node has failed. What happens over those 90 minutes, what sets the real deadline, and what would make the mesh ride it out?

You must move the sidecar proxies of 500 services and 2400 pods from mesh version n-2 to n. The control plane supports one version of skew with its data plane and each proxy upgrade is a pod restart. Several services hold gRPC streams open for hours. Plan the migration so that no service sees an unplanned reset and you can stop at any point.
