Moore’s Law gains in CPU/memory make upside for addressing WAN costs, latency outweigh most downsides in complexity, scaling, high availability
QoS, compression and “WAN Optimization” technologies introduced due to limited bandwidth of expensive private WANs
Packet loss, latency and "chattiness" problems the key issues to be addressed.
Packet loss, latency, bandwidth limitations drive WAN Optimization, WAN Virtualization solutions
Insufficient reliability of Internet, broadband allow continued MPLS dominance despite huge price gap.
WAN Virtualization used by Cloud Services Providers, IT outsourcers a boon to enterprises, a threat to telecom SPs
WAN Virtualization added to traditional HP Services expertise could turn HP’s cloud weakness into a competitive advantage
Diverse WAN connections, continuous monitoring, sub-second response enables RAID-like revolution in enterprise WAN architecture
As RAID did for storage, WAN Virtualization delivers massive price/bit gains without sacrificing reliability or requiring 'forklift' upgrades
NEW architecture, colocation enable at-your-own-pace migration to leveraging public or hybrid cloud services
