    • Agenda What you will take away from this presentation WHAT is Latency? WHY is Latency important? HOW to reduce Latency?
    • Remember...? Do you know what is was like... when we didn’t have high speed internet?
    • Trying to define latency is not simple •  Endpoints aren't 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
    • The true cost of latency can add up A half-second delay will cause a 20% drop in Google's traffic. A tenth of a second delay can cause a drop in one percent of Amazon's sales.
    • 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 isn't 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
