In the past three years, private cloud computing has moved from an aspiration to a tentative reality for nearly half of the world's large organizations. Hybrid cloud computing, however, is where private cloud was three years ago — aspirations are high but deployments low.
Gartner defines a hybrid cloud computing service as a cloud service that spans both private and public cloud implementations, or both on-premises private and off-premises private or public cloud implementations. A hybrid cloud service can, among other things, synchronize and/or replicate data between public and private clouds, and migrate services on a continuous basis between public and private clouds.
In today's blog post, Milind Govekar, managing vice president at Gartner, shared the benefits and challenges of hybrid cloud computing and examined its critical success factors.
Mr. Govekar said:
Overall, hybrid cloud computing extends the benefits that can be gained from cloud computing:
Organizations cannot, however, adopt hybrid cloud services without first implementing a private cloud. We continue to see organizations struggle to implement private clouds and to demonstrate their value because this requires a shift in how IT is delivered, one that involves changes to people, processes and business management.
Many lines of business buy external cloud services without the initial involvement of, or oversight from, IT leaders. To implement hybrid cloud services successfully, IT leaders need to introduce an internal cloud services brokerage (CSB) role responsible for the governance, demand management and delivery of cloud services. Those who do not think and act like an external service provider or evolve into a CSB role will gradually lose the trust of business managers, who will circumvent the IT organization in order to access the IT services they need. This will result in more disaggregation of IT services and reduced value from the remaining shared IT services.
Hybrid clouds also need cloud management platforms (CMPs). IT leaders buy CMPs to manage and govern the delivery of private cloud services alongside public cloud services. CMPs improve the speed at which services are delivered by enabling self-service requests and automated delivery; they also reduce the overall cost of service delivery.
Mr. Govekar will discuss private and hybrid cloud success stories at the Gartner IT Infrastructure & Operations Management Summits 2014, which will be held on June 2-3 in Berlin, Germany and June 9-11 in Orlando, Florida, U.S. Details of the Berlin event are available at www.gartner.com/technology/summits/emea/it-operations/.
