Amazon, Google, and Microsoft Aren't the Only Cloud Innovators Around When it comes to data center expertise, many tech professionals would say that Amazon, Google, Microsoft, and yes, Facebook are driving most of innovation. These companies design much of the hardware and software that they run in their own massive data centers. There's no arguing with that perception, but make no mistake: The big cloud players don't have a monopoly on data center disruption, according to Al Sadowsky, research vice president for 451 Research. That's important to remember, because while many corporate applications are moving to a public cloud like Amazon (amzn) Web Services or Microsoft (msft) Azure, we are still early in the cloud era and many businesses still want to control their own infrastructure for some jobs. Sadowski cites the work that Equinix (eqix) is doing with its home-grown data center management software. Get Data Sheet, Fortune’s technology newsletter. But there are other interesting infrastructure plays out there.
