Get up to speed on Enterprise Service Management (ESM) products with TechBeacon's Buyer's Guide. The coupling of the SDN to the application is also likely to be a key benefit and driver for users to adopt both SDN and SDN in the cloud. While networks have been a largely consistent expense, with little defined return, now they are smart things that can provide benefits to an application workload that goes right to the bottom line. Both enterprises and public cloud providers leverage SDNs these days because applications can self-define the network requirements directly from the application itself. While the potential benefits of SDNs for on-premises systems are well established, you can gain a huge advantage by deploying these in the cloud as well. The value of SDN is that the network can dynamically reconfigure in response to the needs of specific applications. This means that the network will be automatically configured for the workload running on the cloud that must leverage the internal SDN to access data and talk to users and other on-premises applications. Learn how to roll out Robotic Process Automation (RPA) with TechBeacon's Guide. Software-defined networks have been around for years, but their role in the cloud is just now being defined.
