Presentation: "Open Source at Unibet.com - 10x Scalability at Half the Cost"

Track: Architectures you've always wondered about

Time: Friday 14:45 - 15:45

Location: Metropolitan Ballroom

Abstract:

With over four million registered customers in more than 100 countries, Unibet is one of Europe's largest online gaming operators. Gaming products include sports betting, live betting, casino, poker, lotteries, bingo and soft games. Customers bet via websites in 27 languages, and increasingly via mobile phones and other mobile devices.

In this session you will learn about Unibet's continuously ongoing rearchitecture initiatives from a fairly typical monolithic database- centric architecture into a highly scalable one based on best-in- class open source software, while at the same time substantially reducing cost. We have transitioned to a modern front-end architecture (XHTML 1.0 strict, CSS 2.1, YUI, caching, compression, image spriting, CDN striping, etc.) backed by functionally- partitioned application and data tiers. For scaling out, we have simple use-cases where read-only replicas are fine, and others where we use a partitioned, in-memory, domain repository with an eventually consistent database. This session will also cover our use of key technologies such as content delivery networks and DDoS protection strategies.
