” My focus is the SDN over SPB, and while I seek to build secure, resilient, always on infrastructures that are easy to manage and deploy, eventually we have to leave the premise and traverse the WAN. Whenever I have to extend my network fabric over the WAN I am faced with the reality that the single MPLS pipe they pay for becomes my single point of failure.
It doesn’t matter that my SDN network built on SPB has sub second failover, if that WAN link is the only link, my network is down. Those virtual servers and applications are cutoff from the users. I now bring in my carriers and help the customers to create a more resilient WAN.
