As organizations increase their use of Kubernetes in public and Hybrid cloud architectures, it is important not to let a maiden voyage end like a Titanic catastrophe. To ensure ongoing security site reliability engineers must work hand-in-hand with the CISO’s (Chief Information Security Officer) office to implement Kubernetes security.

Summary: The self-sovereign internet, a secure overlay on the internet, provides the same capacity to produce change by numerous, unaffiliated and uncoordinated actors as the internet itself. TLS (HTTPS) is a secure overlay, but it is incomplete because it's not symmetrical. This kind of "layer" is called an overlay network.

Just to quickly recap what’s happened so far, in part 1 I provided the high-level architecture of NVP and discussed the role of the components in broad terms. Next, you need to authenticate the hypervisor to NVP. First, switch over to the SSH session with the hypervisor (you still have it open, right?) Installing OVS.
