Recent market analysis from Cisco demonstrates the torrid adoption of cloud-based services. By 2019, more than four-fifths of all data center traffic, 83 percent, will be based in the cloud (up from 65 percent today). Most of this action will be going to public cloud services, which will account for 56 percent of all cloud workloads. In terms of type of cloud services, a majority will be applications, as the study finds Software as a Service (SaaS) is and will continue to be the dominant mode. Currently, about 45 percent of cloud implementations are SaaS; this figure is expected to grow to 59 percent by 2019, and SaaS adoption is particularly widespread among SMBs.
