Cloud Storage Spending to Reach $22.6 Billion by 2015

Cloud computing demand will drive new IT spending over the next five years, as public cloud service providers and the adopters of private cloud solutions invest in the supporting infrastructure, according to a recent market study by International Data Corporation (IDC). Therefore, the leading managed cloud service providers have been busy expanding their service delivery platforms.

Overall spending by public cloud service providers on storage hardware, software, and professional services will grow at a compound annual growth rate (CAGR) of 23.6 percent from 2010 to 2015, while enterprise spending on storage for the private cloud will experience a CAGR of 28.9 percent. By 2015, combined spending for public and private cloud storage will be $22.6 billion worldwide.

"Despite current economic uncertainties, IDC expects cloud service providers -- both public and private -- to be among the most expansive spenders on IT products and services as they continue to build out their facilities worldwide and expand their service options," said Richard Villars, vice president, Storage Systems & Executive Strategies at IDC.

According to the IDC assessment, the most significant driver of storage consumption over the past three years has been the emergence of public cloud-based application and infrastructure providers. Many of these service providers act as content depots -- gathering, organizing, and providing access to large quantities of digital content.

Meanwhile, other cloud-based service providers have emerged with a focus on delivering IT infrastructure and applications in an "as a service" model. Collectively these companies have undertaken massive storage buildouts as they have expanded their service offerings, entered new markets, and extended their geographic reach.

In parallel to the expansion of the public cloud, many organizations have started to deploy their own private clouds for application, compute, and archival storage. Some of these private cloud deployments -- government and research sites -- are comparable in scope and complexity to public cloud environments, while others are limited in scope.

 Five information requirements are driving storage demands:

• 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 (Big Data).

To meet these diverse requirements, IDC believes that organizations will continue to demand access to low-cost storage capacity -- plus a growing range of complementary advanced data transformation, security, and analytics solutions.

"The challenge facing the storage industry will be to balance public cloud service providers' demand 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," noted Villars.

"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 or archive cloud deployments."

Increased Spending on Public Cloud Computing Services

This week, the world's financial markets have been negatively impacted by continued concerns about the global economic outlook. There has been little good news about the economy lately, particularly regarding the U.S. jobs forecast.

That said, enterprise related IT spending has apparently been one positive forward-looking market indicator -- particularly the current and planned use of managed cloud services.

According to the latest market study by In-Stat, enterprise business spending on IT and telecom services -- which include cloud computing, wireless, wireline voice, wireline data, and business IP/VoIP -- will move in a positive direction in 2011, increasing by healthy 6 percent.

"There will be positive growth across all 20 verticals with education and healthcare & social services leading the surge with growth of 10 percent and 9 percent respectively,” says Greg Potter, analyst at in-Stat.

These forecast increases in spending are across all product groups except wireline voice, which will decline by about half a percent.

In-Stat's latest market study findings include:

• Enterprise spending on public cloud computing services is set to expand 139% from 2010 to 2011.
• Enterprise spending on wireless data is set to approach $17 billion in 2015.
• Enterprise spending in the healthcare sector on wireline data will approach 2 billion in 2014.
• Enterprise spending on wireline voice will remain flat, with traditional TDM services continuing their decline, only reaching $3.4 billion in 2011.

The Top Five Vertical Markets for IaaS Offerings

The cloud computing phenomenon now includes a set of services and technologies that enable the delivery of on-demand computing services over the Internet in real-time, allowing end-users instant access to data and applications from any device with online access.

Although still in its infancy, gaining traction has not been a problem. According to the latest market study by In-Stat, Infrastructure as a Service (IaaS) is set to grow to roughly $4 billion by 2015.

"Growth is expected in all public cloud service segments," says Greg Potter, Analyst at In-Stat.

Many Software-as-a-Service (SaaS) applications have been around for a long time, but now with the advent of entire platforms for these applications they're gaining the necessary visibility among businesses to reach renewed momentum in the marketplace.

Infrastructure-as-a-Service (SaaS) is also gaining increased traction, especially in the small business market.

In-Stat's latest market study includes the following insights:

• SaaS (software as a service) is poised to grow 142 percent between 2010 and 2015.
• Overall public cloud computing (IaaS, SaaS, and PaaS) is set to grow 153 percent from 2010 to 2015.
• Small business (5 to 99 employees) is the fastest growing size segment growing from $2.5 billion by 2010 to $6.6 billion by 2015.
• Small business account for over half of the market in SaaS and IaaS.

According to the In-Stat assessment, the top five vertical markets for IaaS offerings, in terms of 2011 market revenue, will be hospitality and food, healthcare and social services, and retail trade. The bottom 5 verticals will be mining, forestry, fishing, and agricultural services and utilities.
