The first factor is the industry in which the organization is operating. For large providers, vendor-agnostic standardization is the goal and their next target is the top of rack switch. This type of organization maintains dozens of racks or more should pay attention to what these big cloud players are doing. The potential exists for significant savings as SDN allows data centers to move away from single source hardware to the commodity based pricing we see with servers.
The second factor to consider is the size of an organization’s network; which indicates data center with near or above 1,000 active IP addresses as a candidate for SDN. This is true majorly for those addresses that are assigned to virtual machines. The controllers will become a new line item in the IT budget to expect virtual machine vendors to control the switch, rack, and core as the single unit with their software. …show more content…
The forth factor is, that the number of virtual machines (VMs) within an organization’s network; which considers implementing SDN by its total number across an organization’s network. The VM would be more efficient located in a remote data center closer to its clients. The controller would send a command to vMotion the server, while coordinating network changes across the enterprise to reconfigure for the new location.
The fifth factor is, that the organization’s need for agility, flexibility and scalability within the network; which is relevant to cloud center customers where SDN may provide improved flexibility by removing the traditional demarcation points between networks. The remote, local and virtual networks are normalized into a common entity, differentiated by properties rather than physical
