Enterprises Embracing Cloud Computing, F5 Survey Says
In a survey conducted over the summer, F5 Networks found that enterprises are rapidly embracing the idea of both private and public clouds, with 99 percent saying they either had implemented compute clouds or were in discussions about it. About 80 percent said they had at least started trials of compute clouds. However, concerns over security, management and the definition of cloud computing could slow the rate of adoption, according to F5's survey.Enterprises are beginning to embrace cloud computing, according to a recent survey conducted by application delivery networking vendor F5 Networks. In a survey of IT professionals at 250 companies conducted in June and July, 99 percent said they were either discussing or implementing public or private cloud computing solutions, and more than 80 percent said they were at least in the trial stages of deployments.
However, though there is growing interest in the computing model, there also are questions around such key issues as management and security, as well as confusion around the definition of cloud computing, according to Jason Needham, senior director of product management for F5.
"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 and 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."According to F5 officials, while SAAS (software as a service) is most commonly equated with cloud computing, 75 percent of IT professionals surveyed felt that PAAS (platform as a service), and two-thirds said IAAS (infrastructure as a service) are always included in the cloud. About three-fifths said SAAS was usually or always part of a cloud deployment. Access control, security, and server and storage virtualization were considered key technologies for cloud computing. Key drivers for both public and private clouds were IT efficiency, reducing capital costs, easing staff issues and agility.
