www.scalr.net You build your MySQL/Apache based app using their images, and it is hosted on EC2/EBS/S3 in an application farm that will auto grow as load increases, be HA, etc. Really nice. $50 a month. You could setup scalr yourself, but $50 a month is nothing for the convenience. The FOSS project is at: http://code.google.com/p/scalr/ Video of bringing up an application at: http://scalr.googlecode.com/files/scale.swf http://www.techcrunch.com/2008/04/03/scalr-the-auto-scaling-open-source-amazon-ec2-effort/ Rightscale is the other option, but at $2500 up front + $500 a month, thats not interesting at the moment. Spoke with their technical sales guy tonight and they will probably wave the $2500 up front fee for startups soon. Cloud computing is amazing. Totally disruptive.
