While SPB is a very interesting protocol, my questions were about how deep into the virtual environment the protocol extends. While SPB and other networking protocols are considered by some to be network virtualization, I could not see this within the realm of the virtual network and hence, confusion reigned supreme. Depending on who is talking to each other, the same words can mean many different things. What I found amazing, still, is that most people thinks networking ends at the physical NIC within the virtualization host, and that what is inside, does not matter as much as what is outside.
VMware announced its biggest ever bet yesterday buying up virtual networking startup Nicira for $1.26B.
If we are going to start over, why not really start over and reinvent the entire infrastructure and management software industries in the process. That way we end up with an infrastructure that was actually designed for the dynamic, agile, and scalable use cases that we are trying to address with a green field approach, and an appropriate set of management tools as well. Is this going to happen? You can bet that there are already VC funded startups in stealth mode working on it.
