SPONSORED REPORT: SNAPSHOT Hybrid model key to the future of cloud THE CONVERSATION ABOUT cloud models is beginning to change, and for the better. In the early days of cloud, much of the early debate fo- cused on the different merits of two cloud models, public and private, and in which situations it would be better to use one or the other. There's a growing realization, however, that in many cases the best scenario for cloud in government will be one in which agencies have the best of both worlds, with the ability to use either model as circumstances dictate and to manage both models as a seamless whole. The best scenario is the hybrid cloud, which combines a variety of infrastructure with a cloud services model. That might include a colocation-based solution, a man- aged solution or an on-premise solution. The key is portability. In a traditional cloud environ- ment, an agency might deploy some applications and datasets in a private cloud while using a public cloud service for others---but it won't have the ability to migrate applications from one setting to the other. The enterprise, essentially, is split. A true hybrid environment, on the other hand, provides IT managers the ability "to extend the enterprise from on-premise to publicly hosted cloud systems," said Jad El-Zein, a principal engineer at VMware. But portability is only half the equation. In extending the enterprise, an agency also wants to extend the manage- ment tools and security controls, to ensure that applica- tions and data are managed effectively no matter where they reside. As part of that, IT managers should not have to log in to one console to view applications hosted on premise and another console to view applications in a multi-tenant or public cloud. Instead, they should have "a single pane of glass," said El-Zein. A hybrid cloud environment has a number of advan- tages. First, it scales more quickly than a traditional cloud environment, whether that involves expanding capacity for an existing application or launching a new service. Rather than requiring weeks to get new capacity, a hybrid cloud can be scaled in a matter of minutes. Second, it costs less to scale up. Agencies typically must buy hardware and software based on anticipated demands, which means costly capacity might go unused for some time. With a hybrid cloud, an IT manager can scale up as needed. Additionally, a hybrid environment provides another option for disaster recovery and continuity of operations planning. In fact, VMware offers a disaster-as-a-service option for smaller organizations that need a cost-effective solution for protecting its workload. VMware is offering vCloud Government Service through Carpathia. vCloud Government Service is based on VM- ware vSphere, which is widely used across government. vCloud Government Service, provided by Carpathia, is a hybrid cloud solution that meets a broad range of regula- tions, standards and best practices, including FedRAMP. "In the vCloud Government Service provided by Car- pathia platform, we expect to see on-premise vSphere environments connected to vCloud Government Service taking advantage of the binary compatibility of VMware's products," said Jon Greaves, Chief Scientist and Chief Information Security Of cer at Carpathia Inc. • GET THE FULL REPORT ONLINE AT: GCN.com/Cloud2014 Get More Online...
