Hybrid IT is Transforming the Role of IT
|05 марта 2012|
Hybrid IT is transforming IT architectures and the role of IT itself, according to Gartner. Hybrid IT is the result of combining internal and external services, usually from a combination of internal and public clouds, in support of a business outcome."Many organizations have now passed the definitional stage of cloud computing and are testing cloud architectures inside and outside the enterprise 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," said Chris Howard, managing vice president at Gartner. "As a result, the traditional role of the enterprise IT professional is changing and becoming multifaceted. A hybrid IT model requires internal and external IT professionals to support the business capabilities of the enterprise."
Cloud computing's business model -- the ability to rapidly provision IT services without large capital expenditures -- is appealing to budget-minded executives. CEOs and CIOs are pressuring IT organizations to lower overhead by offloading services to cloud providers. However, when IT organizations investigate potential cloud services, the market's volatility reveals that not all cloud services are created equal.
"IT organizations are taking an 'adopt and go' strategy to satisfy internal customer IT consumerization and democratization requirements," Mr. 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."
For critical applications and data, IT organizations have not adopted public cloud computing as quickly. Many IT organizations discover that public cloud service providers (CSPs) cannot meet the security requirements, integrate with enterprise management, or guarantee availability necessary to host critical applications. Therefore, organizations continue to own and operate internal IT services that house critical applications and data.
However, the public cloud has affected internal customers. Because of the pervasive growth of public clouds, many business units and internal customers have used and grown accustomed to IT as a service and have built business processes and budget plans with cloud computing in mind. Now these internal customers are demanding that IT organizations build internal private clouds that not only house critical applications, but also provide a self-service, quickly provisioned, showback-based IT consumption model.
"IT organizations that do not match the request for IT as a service run the risk of internal customers bypassing the IT organization and consuming IT services from the external cloud, thereby placing the company at greater risk," said Mr. Howard. "IT organizations realize that they not only need to compete with the public cloud consumption model, but also must serve as the intermediary between their internal customers and all IT services -- whether internal or external."
IT organizations are becoming the broker to a set of IT services that are hosted partially internally and partially externally -- hybrid IT architecture. By being the intermediary of IT services, IT organizations can offer internal customers the price, capacity and speed of provisioning of the external cloud while maintaining the security and governance the company requires, and reducing IT service costs.
This model of service delivery challenges both the longstanding practices of IT organizations and the business models of traditional IT vendors. Gartner expects that most organizations will maintain a core set of primary service providers (cloud and noncloud) extended by an ecosystem of edge providers who fulfill specific solution requirements.
"Hybrid IT is the new IT and it is here to stay. While the cloud market matures, IT organizations must adopt a hybrid IT strategy that not only builds internal clouds to house critical IT services and compete with public CSPs, but also utilizes the external cloud to house noncritical IT services and data, augment internal capacity, and increase IT agility," said Mr. Howard. "Hybrid IT creates symmetry between internal and external IT services that will force an IT and business paradigm shift for years to come."
