World’s biggest publicly listed online gaming platform World’s leading provider of online Sports Betting One of the largest Poker networks Comprehensive range of Payment Service Providing Integrated gaming portal - 22 languages, 25 core markets More than 20 million registered customers 1,500 employees bwin builds on the strengths of the web in order to tie responsibility and gaming 15 million page views and up to 980,000 users a day
DB size of the benchmark is about 800GB NEC Express core to host SQL Server. App servers are scale-out could be consolidated on few high end machines like DL980 or spread out on lower cost servers. Transactions/sec 5203 tps –business transactions. SQL Server transactions are much lower as they bundle multiple biz trans in single database tran. Clustering used for high availability. Log Shipping for Disaster Recovery. Repl is used in some deployments as way of reporting
