AgendaWhat you will take away from this presentation WHAT WHY HOW is Latency? is Latency to reduce important? 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 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
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.
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
