Some enterprise customers just may never be comfortable putting their most mission-critical applications in the cloud though, which creates a necessity for hybrid clouds, says Allwyn Sequeira, CTO and VP of cloud networking and security at VMware. Enterprises will be willing to use the public cloud for various applications, and they will want a private cloud for their programs they're not comfortable putting in a public cloud. Having the ability to connect those two to create a hybrid environment is what he believes the future of cloud will be. "CIOs want the cloud, but they want to maintain control," Sequeira says.
But perhaps it's not the security that's holding enterprises back; maybe it's the infrastructure. "If you peel the onion back on a number of these providers, they have pretty good security measures in place," says David Goodman, director of the cloud solutions group at Unisys Corp., which advises enterprise clients on cloud strategies. The problem is, despite advancements the cloud can bring around agility and potential cost savings, there's just not a compelling enough reason for enterprises to move existing applications into a public cloud.
"These enterprises have made huge investments in their legacy infrastructure getting that in place," he says. "They accept cloud and are interested, but they'll be going at it at a different pace compared to small and medium sized businesses."
Startups that are building their IT infrastructure from scratch, he says, are putting everything in the cloud, without hesitation. Many enterprises he works with, though, already have infrastructure that can handle the company's IT needs. When companies have new or expanded IT needs, they are willing to go to the public cloud, he says.
As the IT needs of the business continue to outpace the resources, Goodman expects enterprises to move toward the cloud, and even be willing to put sensitive programs in the public cloud. But that, he says, will take time and continued market maturity.
