Nearly three-quarters of enterprises will adopt multiple private and public cloud strategies, the results of a global survey indicate.
The study, commissioned by the information management company Veritas and conducted by Cicero Group, surveyed 1,800 global IT decision makers in organizations with 500+ employees and at least 75TB of data under management. According to a press release, the study examined both the rate at which organizations are moving data to public or private cloud environments and the reasoning behind their decisions.
The study found that private clouds house the largest number of workloads today, with 38 percent in a private cloud and 28 percent in a public cloud. These numbers are expected to grow at rates of 7 percent and 18 percent, respectively, over the next year, signaling growth in both public and private cloud adoption. Traditional on-premises infrastructure makes up 34 percent of workloads today, a number which is expected to decrease by more than a third over the next 12 months.
A multi-cloud future
“The future will be a mix of traditional and on-premises private and public clouds,” the study concludes. The research indicates a multi-vendor approach as well. Nearly three fourths of enterprises are currently leveraging two or more cloud infrastructure vendors to support their workload requirements, and 23 percent are using four or more vendors. More than 80 percent of enterprises rely on service providers, for help with both implementation and ongoing operations, indicating that the heterogeneous and “messy” nature of cloud will continue to be a challenge for IT departments. According to the study, service providers with high levels of support and skills will be invaluable to organizations, particularly as they migrate workloads to the cloud.
Results by industry
When examined by industry, manufacturing led the way in migration to the public cloud with 30 percent of those organizations’ workloads in the public cloud, as compared to 24 percent in telecommunications, 23 percent in both healthcare and financial and 16 percent in the public sector. Despite this significant shift towards public cloud, a sizable number of respondents noted that certain workloads would always remain on premises in either traditional or private cloud environments. For example, 28 percent state that backup and recovery will remain on premises, 27 percent will keep disaster recovery out of the cloud and 26 percent will continue to house archive, data warehousing and relational or OLTP databases on premises.
Cost, control drive shifts to the cloud
More than a third of respondents reported that cost is the primary driver for moving to the public cloud. However, many organizations continue to push workloads to the private cloud. The most common reason for using private cloud is to keep confidential data in country or on-site followed by the belief that private cloud is less risky. Many respondents cited the control they gain as a reason for choosing private cloud infrastructure.
The results are clear: hybrid cloud is the preferred model for enterprise infrastructures. The drive toward hybrid cloud will continue to put pressure on IT and cloud providers to ensure their solutions help maintain data visibility, management and control. In order to help manage the chaos, many enterprises are looking to partners to offer support through the transition.
