Hybrid IT—the result of combining internal and external services, usually from a combination of internal and public clouds—is transforming IT architectures and the role of IT itself, according to research firm Gartner Inc.

In a Gartner Special Report entitled "Hybrid IT: How Internal and External Cloud Services are Transforming IT," Gartner says hybrid IT relies on new technologies to connect clouds, sophisticated approaches to data classification and identity, and service-oriented architecture, and predicts significant change for IT practitioners.

"Many organizations have now passed the definitional stage of cloud computing and are testing cloud architectures inside and outside the enterprise,” Chris Howard, managing vice president at Gartner, said in a statement. “And over time, the cloud will simply become one of the ways that we 'do' computing, and workloads will move around in hybrid internal/external IT environments."

As a result, “the traditional role of the enterprise IT professional is changing and becoming multifaceted,” Howard said. “A hybrid IT model requires internal and external IT professionals to support the business capabilities of the enterprise."

Cloud computing's business model is appealing to budget-minded executives, the Gartner report says. CEOs and CIOs are pressuring IT organizations to decrease overhead by offloading services to cloud providers.

"IT organizations are taking an 'adopt and go' strategy to satisfy internal customer IT consumerization and democratization requirements," Howard said. "Many IT organizations are adopting public cloud computing for noncritical IT services such as development and test applications, or for turnkey software as a service (SaaS) applications such as Web analytics and CRM that can holistically replace internal applications and enable access for a mobile workforce."
