Feedback on web hosting

I just started working at a cloud hosting provider that's building an IaaS cloud service (think "Amazon") built specifically for Drupal. I've been given the task of researching and collecting feedback about what really matters to the Drupal community when it comes to web hosting and would be interested in your opinion. It would be great if you could share a little bit about your background and list the top three things that matter to you in a web host and why. All the feedback that we collect will be used to drive our product roadmap and hopefully build a great platform for the community to use.

Thank you for your help!
