Online Reporting Architectures Behind Load Balancers
- 1. Load-Balancing Architectures for Online Reporting DB’s
- 2. About the fools in the front… Crys Manson No relation to Charlie, though she tries… Senior DBA with Microsoft Advertising Started as a DBA in 2004 with Atlas/aQuantive, acquired by MS in 2007 Manages the primary ETL and reporting systems for Microsoft’s Adserving system collecting and reporting on systems that serve over 400,000 ads/sec every day. Email: crysma@microsoft.com Twitter: @crysmanson John Halunen Senior DBA with Microsoft Advertising Started working with Crys as a DBA in 2005 Managed various systems in Microsoft Adv, including our Search Mgmt and Atlas Publisher ETL and Reporting DB systems Email: joha@microsoft.com Twitter: @sqlmoto
- 3. Disclaimer We are not here representing Microsoft officially These are solutions that we have used or researched, or plan to use. Your environment is likely to be different. Test everything you hear us say in your Production Test environment FIRST. Basically, Your Mileage May Vary (YMMV), be careful, and Trust, but Verify.
- 9. Webservers/Appservers Middle Tier servers Network LoadBalancing / VIP (Virtual IP)
- 12. Simple (online/offline) Paired Reporting db’s on a single server: Refresh/Online Control table indicating status Advantages Disadvantages
- 15. Distributed Refresh Multiple Reporting servers organized in Refresh Groups Control db Control jobs Advantages Disadvantages
- 18. Logshipped One or more Logshipped Primary (HeadNodes) refreshes Ships logs to two or more (groups) of Reporting servers. Use db snapshots to present the data. Standalone server (for emergency situations) Advantages Disadvantages
- 19. SCALABLE SHARED DATABASES http://www.flickr.com/photos/jonsphotos/218704764/sizes/m/in/photostream/ http://www.flickr.com/photos/froboy/2761162751/sizes/m/in/photostream/ http://www.flickr.com/photos/timothymorgan/75593157/sizes/o/in/photostream/
- 21. Scalable Shared Disks Maximizes use of server resources Requires less total SAN space but it must be fast MSDN recommends a max of 8 servers per db Requires at least two sets of disk (R, and R/W) Maybe 4 if maintenance needs are big
- 23. A brief mention of Some Other Options Federation Lots of good resources online Complicated (split databases horizontally to allow processing queries on multiple servers) AlwaysOn Mirroring with up to 4 readable replicas Not really a scaling solution, more of a great way to use your BCP hardware. Next PNWSQL meeting is this topic

- This is actually Crystals favorite slide, which tells you something about how long it’s been since she’s had any scotch, particularly as we just had a slide with some cute 4 legged creatures.I did work hard to find a pic with Lagavulin, which is her favorite…
