The focus of software defined networking (SDN) may be on the data center and carrier networks, but that doesn’t mean campus LANs can’t benefit as well.
New technologies need a compelling reason for IT to adopt them and SDN is no different. Sure, data centers have issues that SDN can address, but users see choppy video and voice as much more urgent problems to solve.
For many, SDN is a data center and service provider play because those two areas have unique scalability and versatility demands that SDN is well suited to address. There is as much value in the campus LAN as well, and I suspect that we’ll start seeing many more reasons why SDN in the campus makes sense. Two recent examples from Aruba and Extreme both involving integration of Microsoft’s Lync unified communications software are illustrative of why.

The cloud approach to telecom solutions is catching on like wildfire as a growing number of vendors offer a cloud version of their products and some report that cloud solutions already account for the major portion of all sales.
In addition to a shift of expenditures from a large capital outlay to a monthly operational expense the reasons companies are moving to the cloud fall into a few more categories including; flexibility in changing capacity levels, speed in adding applications to premise-based solutions while protecting current investments, and disaster recovery back-up.
While much is made of the CapEx versus OpEx comparison of premise- versus cloud-based solutions, it seems those decisions are limited, for the most part, to end users that are in the start-up or “greenfield” mode of their lifecycle. Conversations I have had with many enterprise end users regarding the premise versus cloud decision process, as well as vendors selling telecom solutions, suggest many purchasing situations fits into one of three scenarios. In scenario 1 the business has a premise-based solution but appreciates the ability of the cloud to add capacity when needed and shrink capacity when activity slows down. Such a situation could be a retail contact center with a premise-based solution that must expand and shrink based on the seasonality of their business. Adding remote, home-based agents via a cloud offering is the perfect solution. Scenario 2 are end users with a substantial investment in a premise-based solution but a requirement to add applications and broader functionality quickly and efficiently without scrapping the not yet depreciated investment. The application of a “hybrid” solution allows the business to add applications to existing solutions without scrapping the premise based solution prematurely, before it is fully depreciated. In scenario 3, a few end users see cloud solutions as a method of providing a disaster recovery, back-up system to their premise-based system that will take over operations when disaster strikes. In this situation the cloud solution can be run in parallel to the premise solution and the cloud could take over if and when the premise-based solution fails for any reason, maintaining operations. Although the disaster solution may add significantly to operating costs, in many situations company revenue streams can be preserved, which make it a feasible investment.
