Enterprises selected hybrid cloud services (36 percent) ahead of private (32 percent) and public cloud (17 percent) services, said a survey by Oracle.
60 percent of enterprises surveyed reporting intermediate or mature levels of adoption. This is expected to rise to 82 percent in 2017.
Data security (by 55 percent of respondents), integration with existing applications (47 percent), available skills (45 percent) and hardware costs (44 percent) are the significant concerns about private cloud adoption.
The important building block of a private cloud infrastructure is having effective governance controls in place (cited by 34 percent); followed by standardization of IT (27 percent), winning the support of key decision makers (25 percent) and ensuring strong IT change management (17 percent).
Within private cloud, Software-as-a-Service (SaaS) (68 percent) is viewed as most important ahead of Database-as-a-Service (DaaS) (61 percent) and Platform-as-a-Service (PaaS) (57 percent). This will change over the next two years with DaaS (29 percent) becoming the most important form of private cloud, ahead of PaaS (26 percent) and SaaS (23 percent).
