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)

Cloud Storage: To API Or Not To API

As discussed last week, cloud storage solutions differ in many ways. They can be defined by their pricing model (usage-based or capitalized), their location (on-site or off-site), the granularity of scalability (per-file, standard unit, or per-system), and whether or not they are multi-tenant. But one of the less-discussed but much more technically-challenging differentiators lies in the access method: Some cloud storage systems use a web protocol-based API for access, while others use conventional storage protocols like NFS or SMB. Today we will discuss the implications of which... (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)

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)

Can Spot Pricing Work For Cloud Storage?

Early Bird Savings at Cloud Expo This week, Amazon took a step with EC2 that many had long anticipated: They announced spot pricing for cloud compute instances. EC2 customers can now name their own price, and Amazon will bring compute instances up at variable discount prices according to these "bids". This complements their March 2009 move at the other end of the spectrum, extra-cost reserved instances. This evolution of the cloud compute market was predicted by many, but Amazon deserves credit for making it happen. The obvious next question is whether spot pricing can work for c... (more)
