In its latest Cisco Global Cloud Index (2016-2021), the networking giant predicts that by 2021, 94 percent of all workloads will run in some form of cloud environment and that dedicated servers will be a distinct minority.
That 94 percent covers both public and private cloud scenarios, which means even in an on-premises scenario, almost all workloads are going to be run in a virtualized environment. The days where a server is dedicated to one workload are rapidly drawing to a close.
“We use the definition of one workload or instance with one physical server,” said Thomas Barnett, director, Cisco Service Provider forecast and trends. “In virtual scenarios, we’re seeing one workload with multiple virtual machines and containers. Based on growth in public cloud, we’ve overcome some of the barriers of adoption, such as cost and security and simplicity of deploying of these services.”
The remaining 6 percent of workloads that are not virtualized are highly specialized applications, usually the most mission critical, that need dedicated hardware for 24/7 operation. In some cases, Barnett said, some organizations will be hard pressed to move because they need the control or have that resource managed by someone else.
But even high-compute projects such as data warehouses and business intelligence, which chew through data at full CPU speed and usually aren’t good cloud material, are moving to virtualized environments, he added.
