In mid-2018, VansonBourne conducted research on behalf of Nutanix to gain insight into enterprise plans for adopting private, hybrid, and public clouds. The respondent base spanned multiple industries, business sizes, and geographies, which included the Americas; Europe, the Middle East, and Africa (EMEA); and Asia- Pacific (APJ) regions.
IT decision makers were asked:
- Where they are running their business applications today.
- Where they plan to run them in the future.
- What their enterprise cloud challenges are.
- How their enterprise cloud initiatives stack up against other IT projects and priorities.
- “Private cloud” is used in this report to refer to automated, highly virtualized installations of IT infrastructure managed by an organization’s own IT team.
- “Public cloud” indicates the use of an infrastructure-as-a-service (IaaS) offering managed by a third-party provider.
- “Hybrid cloud” describes the combined use of at least one private cloud and at least one public cloud service, with some degree of integration between the two cloud environments.
- “Multicloud” is referenced in this report to indicate the use of more than one public cloud service.
Building the Ideal IT Model
IT teams are fast discovering that workloads with predictable characteristics, such as the number of concurrent users, storage I/O requirements, and bandwidth consumption, often run most cost-effectively in a private cloud. It’s fairly straightforward to forecast the consumption needs of predictable workloads and to plan accordingly to add resources as needed to accommodate expected growth. By contrast, unpredictable workloads, such as those supporting new customer services or those that are seasonal in nature, often run best in the public cloud. That’s because a public cloud is able to deliver greater IT resource elasticity to satisfy dynamic application requirements.
Choosing the right cloud.
The Nutanix Enterprise Cloud Index 2018 findings support these approaches. Respondents, for example, reported using private clouds most often for more predictable applications like data backup (54%) and internal databases (51%) and said they used the public infrastructure most often for less predictable mobile/ digital (46%) and IoT (41%) applications.
Summary & Key Findings
Today, enterprise IT teams decide where to run a given business application based on factors that include the economics, regulatory compliance, performance, availability, and security of the available infrastructure options. The enterprises surveyed for this report clearly indicated that their use of both private and public clouds would rise sharply during the next 12 to 24 months.
At the same time, they indicated that they would like to see improvements in application mobility and interoperability among cloud environments for greater flexibility in matching applications to the most appropriate infrastructure.
