  3. 3. Remember...? Do you know what is was like... when we didn’t have high speed internet?
  4. 4. Trying to define latency is not simple•  Endpoints arent fixed: –  High speed fiber –  3G or 4G mobile networks•  Consider the location of the ultimate end-users and the networks that connect them to the destination networks•  Who are the ultimate "owners" and "users" of our applications –  Delivering the appropriate service levels, means also measuring and controlling the expected latencies
  5. 5. The true cost of latency can add up A half-second delay will cause a 20% drop in Googles traffic. A tenth of a second delay can cause a drop in one percent of Amazons sales.
  6. 6. Todays complicating factors•  Distributed computing –  Then: Everything in 1 enterprise data center –  Now: Distributed applications can employ multiple servers•  Virtualization adds another layer of complexity –  Virtualised network infrastructures can introduce its own series of packet delays before any data even leaves the rack itself•  It isnt just about ping, either –  Best way to measure and understand latency is to measure the performance of the same protocols that your applications use.•  Understand Quality of Service and what traffic is prioritized
