The ongoing SDN race

Teresa Leung (Computerworld HK) | Oct. 4, 2013
Some of the larger vendors that were seen as slow in the SDN race--compared to some of the smaller firms--took the wraps off their offerings one after another in the past few months.

3) The level of complexity of an organization's network

If there are requirements for a lot of network slicing or segmentation for security and isolation, you might be a good candidate for an SDN. If there are lots of virtual LANs to configure and manage, or there are VLANs that require more automation than others, SDNs might be a good fit.

4) The number of virtual machines within an organization's network

"If you're not at a few hundred, you're probably early," Castelino said. He reiterates that if an organization is running hundreds of workloads, it might be worth taking a look at SDNs. Below that level, and with SDN's immaturity, it might be "way too early" to look at.

5) The organization's need to simplify security measures and control access to applications

The benefit of SDN is that things get done the same way all the time, through policy, even though the environment is dynamic and always changing. Security and network access control in a dynamic environment can be a nightmare. It's important to get policy enforcement right in this regard not only to ease operation but to ensure information stays where it should.
