SDN Q and A: Citrix senior manager netscaler, Phil Caleno

Brian Karlovsky | May 4, 2015
"Re-sellers that build and offer SDN starter kits for customers will get a huge head start," Caleno says.

4. What are the biggest challenges in moving to a software defined networking approach?
Alongside managing organisational change, which we've already discussed, the biggest challenge created by SDN is being able to manage the various interfaces of the network orchestration platforms used -- it's a significantly different approach to the way people are used to managing their networks. Therefore, as SDN gains traction in the enterprise, we expect to see people with traditional computer science backgrounds play an increasingly influential role in business management. These skilled professionals understand how different systems interact with one another, and so can manage networks accordingly.

5. What is driving the shift to a software-defined approach?
Businesses understanding that SDN minimises organisational risk while enabling improved agility is driving adoption. By automating network management, including the applications it hosts, SDN drives down costs, reduces the time needed to implement change, and increases security. These three capabilities align with most organisations' main business objectives, therefore increasing SDN's value to an organisation.

6.Any other points - trends etc?
Business will not linger over its decision to deploy SDN, as has sometimes been the case with Cloud and Big Data where they have continually evaluated whether it's right for them. As soon as businesses see how SDN can benefit their organisation, including saving time and money, they will quickly decide whether it is right for them and make plans accordingly. This is why it's crucial for channel partners to build SDN suites that can rapidly be deployed from today.
