When it comes to the hybrid cloud, enterprises live in a world of parallel play where some applications live in the public cloud while others reside safely in the on-premises cloud. Yet the two are barely interconnected. This scenario falls far short of the promise of a hybrid cloud where virtual machines (VMs) could be provisioned, migrated and managed as one across multiple sets of data center resources. And in large part, it’s the network that stands in the way. “You can create dynamic network infrastructures within [a hosted cloud] environment, and you can create dynamic internal network infrastructures, but they have to stay within those environments,” said Eric Hanselman, chief analyst at 451 Research. Binding a dynamic network in the hosted cloud to the on-premises data center becomes complicated. The problem starts with plain old physics—or the speed of light. Once you break up tiered applications and place the different elements far away from each in dispersed data centers, latency becomes an issue. Requesting more ...
