"Software always defined my infrastructure. When I first heard the term 'software-defined data center,' I said, 'Well, when has it not been software-defined?' And I'm scratching my head today trying to figure that out," said Jon Toigo , CEO and managing principal of analyst firm Toigo Partners International.
He said that application software is built by looking at the business process that was going to be automated, then considering coding features and potentially using off-the-shelf software that could meet those needs. Toigo said infrastructure is built to handle the hosting duties of the data generated in those automated processes.
He went on to say that software-defined infrastructure vendors haven't yet made the benefits clear.
"I ask them, 'How is [it] any better or any different than the way we're doing things today?'" said Toigo, later adding, "It's a different way of doing things. I don't know if it's better, superior or not."
Toigo said that software-defined data centers rely on three key concepts -- abstraction, resource pooling and automation -- to deliver the capabilities of a data center as a set of services. But Toigo said he is concerned that the approach is consumer-driven, and could lead to future issues.
"That scares me more than anything else … and makes the biggest case for why you need disaster recovery capability, because you're going to let consumers decide how to build their infrastructure," said Toigo.
