The research firm IDC has released a new study that forecasts enterprise spending on storage for the private cloud to see a compound annual growth rate of 28.9% from 2010 to 2015, driven in large part by the demand for both public and private cloud services.
Overall spending by public cloud service providers on storage hardware, software, and professional services, meanwhile, is expected to grow at a CAGR of 23.6% from 2010 to 2015. By 2015, combined spending for public and private cloud storage will be $22.6 billion worldwide, the study predicts.
IDC notes that the most significant driver of storage consumption over the past three years has been the emergence of public cloud-based application and infrastructure providers, in particular because cloud-based service providers and content providers like iTunes and Facebook act as “content depots” that require massive storage capacity to allow access to content. The increasing popularity of offering IT infrastructure and apps “as a service” is also a major contributor to the uptick in storage spending, the study notes. Private cloud deployment by large enterprises and the need for archival storage also is a major contributor, particularly when it comes to government and research organizations, according to IDC.
The IDC study points out five information requirements that are driving storage demands in the public and private cloud:
- Enabling more efficient delivery of information/applications to Internet-based customers
- Reducing upfront infrastructure investment levels (i.e., cutting the cost and time associated with deploying new IT and compute infrastructure)
- Minimizing internal IT infrastructure investment associated with “bursty” or unpredictable workloads
- Lowering and/or distributing the ongoing costs associated with long-term archiving of information
- Enabling near-continuous, real-time analysis of large volumes and wide varieties of customer-, partner-, and machine-generated data
