The Symmetry between Gigahertz and Gigabits in Cloud Networking

One of Om Malik's recent blogs I read in Gigaom was thought provoking (as usual!). It made me realize that we have reached a tipping point with the introduction and deployment of powerful multi-core processors. They have begun to challenge the foundation of today's anemic network connectivity. A network running at 1 gigabit is becoming the weak link in the data center. The adoption of just about every web scale application be it File Systems protocols, Map-Reduce frameworks with Hadoop clusters or Mem-cached's giant hash tables, are placing far greater demands on scalability. We are no more limited by compute power as dense cloud computing enables processing speeds of 1.6 peta-flops, which even out paces Moore's law. Compute capacity could vastly outstrip network bandwidth by 2:1 if we are not prepared. In fact, we are more network-bound by Nielsen's Law.
