In a report released October 20, 2011, by IDC’s vice president for storage systems, Richard Villars, the firm calculates that enterprises worldwide spent $3.3 billion for public cloud-based storage in 2010. Villars went on to project a compound annual growth rate of 28.9% for cloud storage from last year on to 2015. That would put worldwide expenditures at an amazing $11.7 billion.

On January 27, 2011, CIO magazine predicted Storage as a Cloud Service as the number one storage trend for 2011 and cited IDC’s growth estimated as well. However, they tempered their enthusiasm for public cloud storage services based on growing concerns over the vulnerability of critical information on public clouds. Hence, they feel the majority of investment in 2011 will go to the private model.

In fact, Gartner predicts that Global 1000 IT organizations will spend more money building private cloud computing services through 2012 than they will on offerings from public cloud-computing service providers. As those customers begin to seek out vendors who can not only store their critical information safely, but can also manage and host their cloud environments, those vendors who are investing in the cloud now will come out on top in the year ahead.

What do you think about the future of public cloud-based storage? Is this Hype (growth of cloud storage is over-stated) or Ripe (enterprise cloud storage will be a game-changer over the next 3-5 years)?
