As cloud computing continues to grow, more users will be accessing their data through a variety of services. The latest Global Cloud Index study by Cisco expects a dramatic increase in cloud traffic over the next four years, The Hosting News reported.

Traffic in the cloud is expected to grow from 1.2 zettabytes today to 5.3 zettabytes by 2017, representing a 17 percent share of all data center traffic.

“People all over the world continue to demand the ability to access personal, business and entertainment content anywhere on any device, and each transaction in a virtualized, cloud environment can cause cascading effects on the network,” stated Cisco vice president Doug Merritt.

But what exactly do IT professionals look to get out of the cloud? A recent study by a hosting provider found that the reliability and uptime of the cloud is what most IT managers look for out of an enterprise cloud, according to CloudTweaks contributor Steve Prentice.

More than 50 percent of those surveyed selected reliability as the number one thing managers are looking for from a cloud deployment. Security was next at approximately 22 percent, while the flexibility of the cloud was third at roughly 15 percent.
