    3. Data Center Networking (DCN) Ever increasing scale Google has 450,000 servers in 2006 Microsoft doubles its number of servers in 14 months The expansion rate exceeds Moore’s Law Network capacity: Bandwidth hungry data-centric applications Data shuffling in MapReduce/Dryad Data replication/re-replication in distributed file systems Index building in Search Fault-tolerance: When data centers scale, failures become the norm Cost: Using high-end switches/routers to scale up is costly 3
