The top three influencers of building the private cloud are IT, 45%; line of business stakeholders, 36% and application development teams, 24%. The top influencers in use of public clouds are IT, 45%; application developers, 41%; and line of business stakeholders, 41%. The numbers do not add up to 100% because respondents were allowed to name several top influencers among job titles in the organization.
The results found, not surprisingly, that cloud implementers want some of the capabilities found in at least one of F5's products. F5 provides access control and some elements of network security, both of which rated high on the list of IT manager concerns.
Applied Research - West targeted which IT managers were interviewed, and spokesmen for F5 said if any of its customers were interviewed, they don't know about it. F5 provided no prospective interviewee names, MacVittie said.
While IT managers disagree on a precise definition of a cloud, 68% supported the two following definitions as correct or "almost there."
The first definition was: "Cloud computing is on-demand access to virtualized IT resources that are housed outside of your own data center, shared by others, simple to use, paid for via subscription and accessed over the Web."
The second was: "Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure in the 'cloud.'"
F5 provided a third definition combining many elements of the two definitions. It is: "Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service. Users need not have knowledge of, expertise in, or control over the technology infrastructure in the 'cloud' that supports them.
Furthermore, cloud computing employs a model for enabling available, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, services) that can be rapidly provisioned and released with minimal management effort or service provider interaction."
