I am trying to evaluate Gravitational Teleport to be for maintaining our own architecture as we will expand soon looking into building clusters. It seems a containerized cluster using Kubernetes is where the bleeding edge is happening and SSH'ing into instances seems more like something you would want to do if you want to manage a lot of VPS yourselves rather than having an immutable infrastructure.
So is Teleport a parallell technology to Container / Kubernetes / Immutable Infrastructure or is it orthogonal, as in, can be used in addition?
