Zero Downtime Patching in Action
Whenever I talk about high availability in SharePoint and SQL Server Always-On Availability Groups I inevitably get a bunch of questions about the "zero downtime" patching concept first introduced at last year’s Microsoft Ignite conference. There seems to be a great deal of confusion about this topic, with many people wondering how it works, what happens to servers while they are being patched, how database updates are applied, and numerous other potential issues. On the surface, it sounds simple enough but as with everything SharePoint-related the devil is in the details.
Thankfully, some of the great folks at Microsoft who regularly deal with enterprise customer issues have put together a video guide on this topic to dispel any confusion about how it all works. Neil Hodgkinson, Bob Fox and Karl Reigel do an excellent job breaking down the requirements, explaining the functionality and then showing how it all comes together in a step-by-step video walkthrough. This should go a long way towards clearing up any confusion and helping customers understand how to take advantage of this functionality in the higly available SharePoint farms. Job well done, guys – thanks for putting this out there.
