Truth and Lies about Latency in the Cloud

Jelle Frank van der Zwet Global Marketing Manager Cloud

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
