According to the Cisco Cloud Index, 68 percent of the cloud workloads will be in public cloud data centers by 2020, which is a 35 percent jump from 2015. While that growth is impressive, what it doesn’t say is that many businesses are still trying to figure out the process of moving to the cloud. AWS, which currently holds about 40 percent of the market, clearly has a lot to offer. What is not as clear are the hidden costs of moving infrastructure to the cloud.
