The Nebula appliance announced today jumps right into this space and provides a standardized hardware configuration for OpenStack implementations. It offers scaled-out compute power based on commoditized x86 CPUs and standardizes a configuration of switches and other components to glue a large number of these CPUs together. The new VC-backed startup will thus compete head to head with EMC’s Vblock and Microsoft’s Azure appliance; neither of these are based on open source, and the latter isn’t really on the market yet.
But Nebula is more than just a hardware deliverable. Its mission is to transparently standardize the cloud hardware stack. Basically, it’s nothing more than the complex specification Microsoft worked out with its hardware partners (Dell, Fujitsu, and HP) to deliver the Azure appliance to local cloud providers and large-scale private clouds. However, Nebula’s openness is the differentiator; it reminds me a bit of IBM’s approach around the original personal computer back in the 1970s. Sure, it enabled hardware competitors to produce compatible PCs — but it also brought mass adoption of the PC, outperforming Apple over four decades.
If Nebula delivers a compelling price point, it has an appealing approach that could gain significant share in the growing cloud hardware market. If the new company aims to spur a revolution similar to that of the PC, its founders need to tweak their strategy soon:
