Hybrid Network Unification – Two birds with one stone [business continuity + application performance]

WAN Governance | May 29, 2010

In his "Cost Cutting by Rightsizing Network Reliability" report [ tinyurl.com April 2008 ], Neil Rickard (vice president in Gartner Research) suggests that "Enterprises should grade their sites by reliability needs because this is the biggest factor driving WAN costs" and proposes three key findings:

* Combining multiple, less-expensive services in parallel can deliver the same levels of reliability at lower prices than a single, high-quality connection.
* Reducing the reliability target for a location by one "9" (for example, from 99.99% to 99.9% availability) will typically save 30% of the WAN costs for that site.
* Transition costs, such as installation charges for new services, will typically eliminate half of the first year's savings.

This statement is the traditional driver for hybrid networking: adding a secondary link over Internet would provide the expected availability improvement (basically an additional "9") sought by IT and network managers while being (most of the time) cheaper than a second MPLS access line.
