Many in the IT industry seem to enjoy arguing exactly what does and does not constitute a cloud service. As I mentioned in my post on the controversy over private cloud services, I do not feel that these arguments are productive. We should focus on results and business value instead of arguing about semantics. However, the current crop of cloud storage solutions have many important differences from traditional SAN and NAS storage, something that seems to surprise many end users I meet. Cloud storage capacity is not your fathers blocks and files! Primary, Secondary, and Tiered Storage Most IT infrastructures contain a wide variety of storage devices, but these have traditionally been divided into two categories: Primary or production storage serves active applications and is accessed randomly. The primary category includes most familiar direct-attached disks (DAS), s... (more)

Addressing Enterprise NAS Priorities

The Enterprise Strategy Group forecasts that the enterprise NAS market will continue to grow like gangbusters over the next two years, reaching 62,000 petabytes in 2012! That number represents a huge sales opportunity for EMC, NetApp, Dell, HP, IBM, BlueArc, and the rest of the traditional NAS array market leaders. It also represents an opportunity for vendors like F5 with their file virtualization systems, as well as cloud storage service providers like Nirvanix with CloudNAS.

Zebras, Giraffes, and Horses

My youngest daughter used to have trouble with her animals. Whenever she saw a giraffe, she would say "zebra" and whenever she saw a zebra she would say "giraffe!" Although an adult would never make that mistake, one can understand why a child would: She was new to these names, and they were entirely arbitrary words. Besides, both are quadrupeds with bizarre coloration and patterns. But my daughter definitely knew a horse when she saw one! Private Clouds and SSPs: Horses and Zebras Today's cloud storage world can be equally confusing to the uninitiated. Long-time IT folks rememb... (more)

What Do We Call This Cloud Storage Thing?

Not all cloud storage is equal, but it's even difficult to talk about those that are more comparable. Does an API make it a platform? Are all APIs the same? Setting these questions aside temporarily, we come to a more fundamental question: What should we call cloud storage services, anyway? The Case for "Platform as a Service" (PaaS) Platform as a Service is variously defined, but it generally refers to a middle layer between infrastructure (hardware and software) and applications. Cloud platforms offer simplified interfaces for a new generation of applications that use web protoc... (more)

Is a Private Cloud Worthwhile?

Much discussion in the cloud computing world has focused on a simple question: Is a private cloud infrastructure worthy of the name? It's been posed in many ways, with some going so far as claiming that there is no such thing as a private cloud. Although discussions like these are all too common in many areas, the question really amounts to little more than counting angels dancing on pin heads. The key issue is whether private cloud-style infrastructure can deliver real benefits like public clouds can. First, let's set out some definitions: The draft NIST definition, perhaps the ... (more)
