Marketing could be a double-edged weapon. Now Microsoft presents its cloud platform Windows Azure as the almighty thing which is perfectly able to run almost every popular third-party development framework and technology. There are numerous sessions on every development conference led by Microsoft about PHP, node.js, hadoop, etc.
It seems that instead of telling people “You are able to use all popular technologies and frameworks with Windows Azure, but you’ll get the best when using ours” they actually tell “Now you don’t want to use our technologies with Windows Azure, look how cool is using node, ruby, php, etc.”
When silverlight was discontinued, it was a huge impact on people attitude to Microsoft technologies, please, please, don’t do this one more time.
