How to stay ahead as we migrate away from traditional route switch

For the past ten years, I have been a traditional route/switch network engineer.  I have worked with spanning-tree environments that needed to be cleaned up.  I've helped transition between protocols like MSTP, STP, and Rapid-PVST.  I've looked at the routing protocols and helped migrate from RIP to EIGRP or OSPF.  Looking at the WAN, we have MPLS, DMVPNs, and other carrier-grade circuits running various IGPs or BGP.  I've worked in the data center and held firm my delineation where the network ends and other teams begin.  But, is that the world we live in today?  No. For the past five years, I have become more intimately involved in technologies such as storage (storage pools, LUNs), server virtualization (multi-hypervisor, configurations, deployments), security, load balancing, and more.  That said, I know I'm not the only one.  I hear this from companies who are going through the transition or those that have completed it.  Some companies will maintain this segregation and siloed environments for a while, but the shift is here and the time to evolve is now.

Firewalling within SDN - Bending the Unbendable

Software-defined networking continues to be a hot topic for businesses looking to streamline their networks and data centers.  With single pane of glass management, SDN offerings ease management workload as well as offer powerful automation tasks to enable your team to work smarter. Cisco’s offering to this realm, ACI, follows suit.  Under the covers, ACI functions by bending the traditional understanding of routing and switching.  IP addresses, MAC addresses, VLAN tags, and other familiar networking components are treated more abstractly, with the fabric doing much of the heavy lifting for you.  But what if you’re looking to take your SDN network to the next level: for example, how would an ASA firewall, abiding by the strict rules of traditional networking, mix with an SDN environment?
