Hi, Good luck on the launch! It is always an interesting time.. we are just about to launch our Cloud into Public Beta, so its busy times for us as well.
In answer to your questions, you should be looking for a VPS/Cloud based solution that is highly available and is backed to centralised storage. If you wish to host from your own server/vps (I assume the applications are mission critical based upon your email), the options you should look out for are as follows: - *High Availability* - check that your hosting provider is able to start up your instance on another server rapidly after a physical hardware failure. This requires the VM to be running on a network based storage device (such as a SAN) which allows it to be accessed on multiple physical hypervisors. - *Redundant Storage (Non Local) *- ensure that your vm is stored on a redundant, network attached, storage array. By redundant, I mean at least two physical storage arrays (not simply two management cards) on different physical servers/sans. Many providers use local RAID arrays, which are great for speed and latency, but tie your vm to that server. If this server has a hardware problem, you will be off the air until it is restored. Also this does not ensure good redundancy for storage as you are still backing to one array of disks. For US based clouds, Amazon and Rackspace are the two well known, but bear in mind that storage on Amazon is quite slow (EBS) and those on Rackspace are backed to a local RAID10, so they are not multi-node redundant. In regards to a CDN, these are used for delivering your large static files more efficiently. Files are delivered by the node closest to the client, but as this is done via caching it is usually only suitable for static content such as images, js files and video content. If this is what you require, it may be best for you to use AWS as you will be able to use EC2, EBS, S3 and Cloudfront to both host the application and deliver content via a CDN. If your application is latency sensitive, try to use providers in the country with the greatest amount of clients, simply because it will make applications run faster and usually has more locally specific support. Let me know if you have any further questions. Hope this helps.
