Although the capacity of storage systems keeps growing, data growth keeps absorbing available capacity. In an effort to contain costs, IT organizations turned to tiered storage but have encountered a "glass floor": Disk space is a small component of costs, reducing the impact of hardware solutions. IT organizations have long turned to outsourced services to enable cost savings on non-core infrastructure and organizational elements, and manaed storage as a service promises to deliver remarkable savings. Why isn't storage getting cheaper? This series of articles attempts to answer this question: Too Cheap to Manage Too Much to Manage Tiered Storage The Glass Floor Storage as a Service Storage as a Service Managed services are not a new idea, and savvy IT organizations have been benefitting from their application for many years. Managed storage as a service has existed... (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)

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)

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)

Cloud Replication Is Not Backup, But Backup Is!

Early Bird Registration at Cloud Expo Go read that headline again: W. Curtis "Mr. Backup" Preston points out on his blog that replication is not backup, and we can't disagree. Keeping alternative copies of data in multiple locations is a great idea, reducing the risk of data loss and potentially enabling enhanced access, but it's not a historical data protection (aka, backup) strategy. Backup requires management of multiple historic copies of a data set. Clearly, cloud storage in itself isn't backup. Backup vs. Storage SNIA defines "backup" thus: [Data Recovery] A collection of da... (more)
