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)

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)

Cloud Storage, Storage in the Cloud, and Cloudy Storage Systems

As I discussed in my previous post, What Makes Cloud Storage Different from Traditional SAN and NAS?, today's cloud storage is unique from the SAN and NAS (and even CAS) that has gone before. Beyond the cost and flexibility benefits inherent in public cloud computing resources of all sorts, cloud storage is unique in its openness, programmability, and the possibilities it opens for distribution and collaboration. These compelling benefits, along with an explosion of cloud hype, have led every company with a product even remotely "cloudy" to jump into the market. In my corner of ... (more)

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)

Everyone Should Be Skeptical About Cloud Service Providers

As we plummet down into Gartner's "trough of disillusionment", the cloud skeptics are making their voices heard. Although my professional focus is at the forefront of the cloud storage wave, I can not disagree with the content of articles with sensational headlines like "Cloud Storage: It's Strictly For Airheads" and "Why Cloud Storage Use Could Be Limited in Enterprises". The authors are doing exactly what everyone should be doing: Questioning the viability and suitability of cloud storage in the enterprise. The truth is, although I'm not the "cloud police", not all managed stora... (more)
