Can multiple unique services mesh solutions exist in the same cluster?

Can Consul and ISTIO (for example) co-exist and function together in a same multi-tenant container environment?

Hi @gene.garrett!
I believe it is possible, but it is not a configuration that we test for or generally support. In theory it may work as long as you keep the installations separate and pay careful attention to your resource labels so as not to cause a pod to be injected/mutated by both Istio and Consul.
I hope that helps!
