To avoid this, Enterprise Management Associates' Frey recommends using tools to map application interdependencies and devising cloud strategies to accommodate them. "Get some measure of what applications are drawing off each other and then you can move them closer together vs. taking a hit on latency," he says.
Much like an internal network, bigger bandwidth sometimes is the only solution to congestion. If you're suddenly pushing all of your users out to cloud-based services such as Google Apps, then you're going to need fatter pipes from your building and remote offices. This reality has to be weighed when deciding to head to the cloud.
Although bandwidth has mostly taken a backseat to other cloud-related considerations, analyst Lanowitz says now is the time to bring it to the fore. "The risk for failure is growing because the company brand is now inextricably linked to the technology running," she says. That said, companies can't hand over bandwidth quality control to external providers -- it's something, she says, that must remain in-house.
