Today at Teched in Barcelona Microsoft briefly mentioned cloud witness during a Storage replica demo in the keynote. I was wondering if this was somehow limited to this specific scenario. So I checked this new feature with Mark Russinovich who is now Chief Technical Officer of Microsoft Azure. He confirmed that the cloud witness feature will work with any fail-over cluster scenario, so also for Microsoft Exchange, meaning in the future you can have a stretched Exchange cluster with nodes running in 2 separate datacenters (2 sites) supplying quorum by a witness in Azure (3rd site). This provides much easier implementation for site fail-over and recovery.

The option for a witness in the cloud has been a much requested feature for years now, so this quick mention in the keynote is a huge announcement in my opinion. Smile

Tweet Microsoft has a long, and not very successful, history with eReaders, going all the way back to Microsoft Reader, which debuted in 2000, but never made it beyond Windows Mobile and was shuttered in 2012. Since then, Microsoft hasn’t delved into the 1st party eReader market, although it has seemingly been ready to make the jump a number of times, establishing a partnership with Barnes and Noble and its…

Stats for Chrome’s Compression Proxy

Tweet A few Google engineers wrote an interesting paper (PDF) about Flywheel, Google Chrome’s data compression proxy. The paper only talks about the data compression feature from Chrome for Android and iOS and offers a lot of stats.
