Slides from my presentation about Shopzilla's concurrency strategies to the Pasadena Java User's Group on April 26, 2010. This is essentially the same material as covered by my colleague Rodney Barlow in an earlier presentation http://www.slideshare.net/rodneypbarlow/shopzilla-on-concurrency, with a few minor tweaks.
Today I’d like to share with you Shopzilla’s redesign of our consumer site and content delivery infrastructure.
So we’ve built an architecture that we believe to be performant and scalable. How do you go about testing this? There are a lot of moving parts * Highly concurrent requests, dozens of services, resource accesses Strategy: Each service is performance tested in isolation to its SLA. Then the full stack is performance tested
Shopzilla is one of the largest and most comprehensive online shopping networks on the web through our leading comparison shopping sites Bizrate.com and Shopzilla.com and the Shopzilla Publisher Program We help shoppers find best value, for virtually anything from 1000’s retailers Across our network we serve more than 100M impressions per day to anywhere from 20-30M unique visitors searching as many as 8000x/second for more than 105M products
