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 cloud storage. Although there are cases where spot pricing might make sense, the nature of data storage trends against this sort of pricing model. Let's explore the question further. Cloud Compute Cloud compute is obviously different from cloud storage: The former deals with running applicat... (more)

What Makes Cloud Storage Different from Traditional SAN and NAS?

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 St... (more)

Cloud Storage Flavors: Platform/Infrastructure and Service/Product

Take a look at the various data storage offerings called "cloud" and your head will start to ache. How can so many things all bear the "cloud storage" name and yet be so totally different? The answer is obvious to long-time industry observers: Each provider has tailored their offering to make it distinct in the market, and each supports different use cases Infrastructure versus Platform Although I am not one to tilt at windmills, especially when it comes to arguing the "rightness" of cloud-based marketing, I sometimes do hit upon a set of terminology that makes sense to me. Wading... (more)

Cloud Integration Mixes CommVault Simpana Management With Cloud Storage

One of the smartest data protection and archiving suites out there is CommVault's Simpana. Mixing their intelligent software with the benefits of cloud storage for data protection makes a killer combination! This is precisely what CommVault announced this morning.

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)
