These technologies are the elements that make cloud computing possible. Without virtualization, there would be no resource pooling. Advances in networking allow for ubiquitous access. Improvements in storage and databases allow remote virtual storage in a shared resource pool. Orchestration puts all the pieces together. The combination of these technologies allows better resource utilization and improves the cost structure of technology. Providing the same resources on-premise can also be accomplished by these technologies, but with lower resource utilization and at a higher cost in many situations. Where costs are not decreased by cloud computing, a case for on-premise resources can be made.
