IDG Contributor Network: A software defined network requires reinventing IT devops

It’s common for a newly released application to have a few bugs in it. Customers may grumble, and IT service requests may increase, but life goes on and people will figure out how to work around the issues. The same cannot be said for a network software upgrade. If the network goes down, everything grinds to a halt, and service to employees and customers ceases.

In the old hardware network model, an operator relied on three to four vendors to run annual or semiannual upgrades, and even that process put the network’s resiliency at risk.  As networks transition to a software model, they are supported by a myriad of best-of-breed partners and a more diverse ecosystem, increasing the frequency of updates and therefore the degree of network vulnerability. In addition, the technology implemented is less mature, resulting in greater network exposure to errors and risk.
