I use Azure and prefer it to AWS. You can get managed Azure or AWS solutions through Rackspace too, if you don&#x27;t want to rely on Rackspace natively.<p>Anyhow, Microsoft&#x27;s revenue is exploding in this space mostly because it lumps in Office 365; not really because of Azure itself, which I think is a great product. Azure has a few short falls that are annoying...still preferable to AWS though.<p>AWS is still very popular with extremely popular apps which drive its revenue lines. Netflix, Tinder, etc all use AWS. However from my experience with Azure they could lower their cost if they had Azure installs, AWS likes to keep instances up and spinning which eats into your costs (and they are enormous) Azure has better auto-scaling and it shows. I can&#x27;t bare to imagine how much Amazon makes off of Netflix&#x27;s AWS usage, you&#x27;d think they&#x27;d want to get off of their competitor&#x27;s platform...but I guess it costs a lot to migrate.
