• Metrics that Matter - Approaches To Managing High Performing Websites

  metrics are the only way to really measure the things that you care about, especially the more they are related to business the better…

• Getting to Second Base With Your CDN

  @Vitaly: Mainly the point there is that you want almost all of your requests to serve from cache on the CDN. You pay for delivery between the CDN and the end-user.

  If you do not cache your assets well on the CDN, or fail to cache them at all, then with every request for a file you are paying for bandwidth to (1) deliver the asset from your origin server to the CDN and (2) for the delivery from the CDN to the end user. That’s the “double” payment.

  When you cache assets properly, the cost of delivery from your origin server to the CDN should be negligible next to the cost from the CDN to the end user.

  This applies when using your CDN as a reverse-proxy or “origin pull”.

• Getting to Second Base With Your CDN

  Thanks for great presentation!

  Unfortunately, I didn’t understand about which case/solution you speak in “Avoid double paying” slides. Can Mike or someone explain this point?

  Thank in advance, Vitaly

Web companies of all sizes face many of the same challenges: sites must be faster, infrastructure must scale, and everything must be available to customers at all times, no matter what. Velocity is the place to obtain the crucial skills and knowledge to build successful websites that are fast, scalable, resilient, and highly available. It’s a unique opportunity to learn from your peers, exchange ideas with experts, and share best practices that will help maximize your company's efficiency, performance, and responsiveness.

A full day of workshops and two days of sessions, offered in dedicated Web Performance and Operations tracks, will help you and your company:

• Understand the Operations "secret sauce" used by sites like Flickr and Facebook, and learn how to bring it home to your company
• Get the latest on the best performance tools to use and the next wave of browser features that will make your pages load faster than ever before - if you know about them!
• Find out how to automate your infrastructure and stay efficient and nimble, no matter how fast you grow or how big you get
• Learn how to speed up web pages to improve the customer experience and drive down operating costs
• Learn firsthand from developers what they they love and what they hate about using Cloud services like Amazon's EC2/S3

Velocity brings together representatives from industry leaders like Google, Facebook, Microsoft, eBay, AOL, MySpace, and more — you’ll meet the people who are doing the best performance and operations work in the world. Some of the featured speakers and sessions at Velocity 2009 include:

• Douglas Crockford (Yahoo!) — Ajax Performance
• John Allspaw and Paul Hammond (Flickr) — 10+ Deploys Per Day: Dev and Ops Cooperation at Flickr
