One more thing…

214291449_b0d7e78356_b So, if I started ranting on Microsoft, here is one more thing: you should never ever use Microsoft servers if you want to scale. The reasons is simple: currently the best scaling method is horizontal (ie. buy loads of cheap hardware and distribute the load between them). Using Microsoft server software would mean that for each server you would need to buy at least one license (or more, like in the case of MS Windows + MS SQL Server). This can easily cost you almost as much (if not more) than the hardware itself.

As far as I’m aware, only Microsoft and hosting providers (which recoup the cost from their clients) are running MS servers in large numbers. This is sustained by a quick check of the top ~5000 sites (as defined by Alexa) – less than 16% of them run IIS. To paraphrase Eminem:

Be smart, don’t be a retard! You take advice from someone who run their front-end webserver tier on VM’s, even though it makes no sense from a technology standpoint to do so?

PS. Yeah, there is the BizPark program from MS for startups – but we yet have to see the first large-scale success emerge from it (BTW, one of my favorite site – StackOverflow – runs Windows Server trough the BizPark program – and even they now use a Linux VM!).
