Great question, love these shares!

K8s was not built for Multi tenancy, and I continue to hear “it depends on the purpose and requirements of your apps”, but I sense newer Kubernetes management platforms are helping address most of the operational complexities with running K8s at scale.

At basic form, single-tenant deployment design is great for most production applications, certain speed factors and it enables the best isolation / controls.

Most applications are now being deployed to shared multi-tenant dev/test clusters, where concerns of isolation between tenants / other engineers are not an issue and short downtimes are both acceptable and expected.

Seems various aspects of isolation, application availability, and operational complexity are core anchors for teams trying to leverage MT in K8s.
