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 best we have at this point, states that "Cloud computing is a pay-per-use model for enabling available, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, services) that can be rapidly provisioned and rel...

When Is A Copy A Backup?

Ocarina's Carter George continued the conversation on backups, asking if the conventional backup paradigm was obsolete, and if file copies could serve the same purpose. As mentioned in our "What Is a Backup?" post, this is the same question posed by EMC's Scott Waterhouse recently. Putting Copies To The Test George suggests a copy-based scenario: "Why not just move files that are candidates for being backed up to a separate tier of storage, keeping them as files in their native format, and organizing them in time coherent views?" To determine whether this is truly a backup, let's a... (more)

Is Cloud Storage The Right Tool For The Job?

The current economic climate is pushing many to look for current-year budget savings. This is one of the major reasons that cloud computing in general, and cloud storage specifically, has become so attractive. Moving data into the cloud doesn't just get it out of the data center, it converts a capital expense (storage equipment) into an operational one (monthly fees). But cloud storage isn't right for every application: One must profile applications and consider where cloud storage or computing services makes sense. The folks over at Cleversafe recently proposed five questions to... (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)

Why Isn't Storage Getting Cheaper? Part 3: Tiered Storage

The growth of storage capacity led to an attitude that storage was too cheap to manage, but this didn't last long. Before we knew it, IT was faced with a flood of data, easily too much to manage. Faced with limits to their ability to control data growth, IT tried to get the business interested in information lifecycle management (ILM). When this didn't work, they opted for cheaper capacity. Today, we look into the outcome of this tiered storage adventure. Why isn't storage getting cheaper? This series of articles attempts to answer this question: Too Cheap to Manage Too Much to... (more)
