Everyone thinks they want active/active data centers. Two DCs running at the same time, supporting customers sounds ideal. If one DC goes down, the other DC carries on, and customers shouldn't know the difference. Isn't that an improvement over the down time suffered when shifting to a disaster recovery site? The reality of life with active/active data centers is more complex.

In this session, network architect Ethan Banks will present a number of points to be considered by any organization evaluating an active/active DC design. The session will discuss challenges related to network bandwidth & latency, real time vs. non-real time data synchronization, inbound customer traffic routing, stateful firewall inspection, cross-DC load-balancing strategies, issues tied to global server load balancing, and the harsh reality of partial failures.
