Software defined fundamentally means two core ideas. To abstract how you tell stuff to do stuff from the stuff that does it.For example - For layer 3 network with specific topology, the network admin literally logs into the switches and routers. This is very fragile, error prone and difficult to automate. In SDN, the control plane that creates network topologies and network services is decoupled from routers and switches.
The second core idea is around data plane to execute software on commodity hardware that drives more flexibility and choice than just economics in the deployment models.
SD compute is real that everybody does it today. SDN is pervasive with service providers but they will be relevant within enterprises' more agile self service clouds in 2014/2015. In next couple of years, SDS will become omnipresent including software on top of commodity storage stacks.
ViPR forms a foundation of securely transporting and accessing data across virtual platforms and across perimeters-making two-way secure bursting a reality. It allows private clouds to finally become flexible. How do you see it?
That's one part. The other objective is addressing real open standards in storage land around control planes which have been tried in the past. The storage industry is the least standardised. The networking land is pretty good with IEEE standards which few years later drive another standard -Next Gen WiFi standard.
Every storage vendor does it totally differently. It is not a conspiracy though it probably feels like one to some customers. It is because the storage architecture of each vendor is radically different to one another. Servers are much commoditised and very standardised. There is a degree of innovative like UCS but the band of innovation is quite constrained.
ViPR aims to make an open flow of Storage to configure infrastructure in a heterogonous whether EMC or non EMC. It works as a software based platform which is the resting point for data services like abstracting information between geographically locations and to be able to move in and out of data centres you have or you rent.
Technology vendors are inspiring CIOs around big buzz word - Big Data. There's lot of talk about Velocity, Variance, and Volume, but too little about other V — that is business Value. Doesn't that restrict its image to big enterprises only?
We are clearly in the hype cycle for big data. You can write it off as the manufactured outcome of vendors but it is usually triggered by disruptive technology like hadoop or flash in storage land. We found that no one was focusing on value. They were focusing more on how and what like how many nodes in Hadoop cluster, specific query launches and other things.
