企业的IT策略正迫于压力做出改变，云计算在修正方案中变得越来越重要。IDC分析家希望企业IT商店可以增加私有云方案的实施。这些云方案中的核心部分往往是存储。

　　预计2010年至2015年，私有云存储的花销将达到28.9%的年均增长率。照此速度，私有云存储在2015年前将翻三倍。这比当前年均增长为4%的内部存储要巨大。报告指出，虽然未来四年会看到云服务收入的巨大增长，但是要求公共云和私有云供应商花费的资金也同样巨大。未来四年，私有云与公共云供应商预期成为IT产品花钱最大方的两大巨头。

　　IDC存储与IT执行策略的副董事长Richard Villars编写的报告称：驱使云存储增长的主要原因是对“大数据”的需求。

　　Villars 说：“‘云’作为传递信息服务的另一种方式兴起将会继续成为IT市场改革最重要的开发之一。存储产业有潜力成为这种趋势下最大受益者，但是供应商必须在目标存储、自动分层数据、大数据处理和高级存档服务等领域推动先进软件方案的同时，均衡云客户对低成本硬件的增长需求。

　　IDC报告引用了企业赞成内部存储方案云的五大理由：

　　更高效地向应用的互联网用户传送数据或信息。

　　降低基础设施投资成本

　　抵消存在无法预测工作的应用程序响应性

　　分销长期信息档案的成本

　　使客户、合作者和机器生成的大数据分析有类持续性与实时性

　　Villars 说：“未来十年，大数据开发也许是存储解决方案供应商最关键的新市场。提供强大的完整大数据解决方案的产品组合——硬件、软件和实施服务——会成为成功的关键因素。同样，强大的动态文档存储方案会成为私人内容/文档云部署的关键微分器。”

Enterprise IT strategies are under pressure to change, and increasingly the cloud is becoming an important component in revised strategies. Analysts at IDC expect that Enterprise IT shops will increasingly implement private-cloudsolutions. And often the central component of these cloud solutions is storage.

Spending on private-cloud storage is expected to increase at a compound annual growth rate of 28.9 percent from 2010 to 2015. At that rate, private-cloud storage will triple by 2015. That’s huge compared to the growth of on-premise storage which is growing currently at about 4 percent annually. The report notes that while revenues for cloud services will see huge growth over the next four years, the amount of money that public and private cloud providers will be required to spend is equally huge. Private and Public cloud providers are expected to be two of the biggest spenders on IT products over the next four years.

The IDC report, authored by Richard Villars, vice president of Storage and IT Executive Strategies at IDC, says that much of what is driving that growth of cloud-based storage are the demands of “big data“.

Villars said that “the emergence of the ‘cloud’ as an alternative for information services delivery will continue to be one of the most important developments in the evolution of the IT market. The storage industry has the potential to be one of the biggest beneficiaries of this trend, but suppliers must balance growing demands from cloud customers for low-cost hardware while boosting demand for advanced software solutions in areas such as object-based storage, automated data tiering, Big Data processing, and advanced archiving services.”

The IDC report cites five main reasons why enterprises are favoring cloud-based over on-premise storage solutions:

　　More efficient delivery of data/information to internet-based users of applications.

　　Lowers infrastructure investment costs

　　Evens-out the responsiveness of applications that have unpredictable workloads

　　Distributes the cost of long-term archival of information

　　Enables near-continuous, real-time analysis of Big Data generated by customers, partners and machines

Villars said that “Big Data developments will be perhaps the most critical new marketplace for storage solutions providers in the coming decade. Providing a strong portfolio of complete Big Data solutions — hardware, software, and implementation services — will be a high priority to succeed. Similarly, a strong portfolio of active archival storage solutions will be a critical differentiator for private content/archive cloud deployments.”
