Aegir can do: many sites, managed updates, many servers. [can it spin up EC2?]; Frontend and backend can be used separately
Mass hosting
Updates via update.php, but in a way you can roll back (uses a mysqldump rollback point)
Automated testing
Manages SSL keys
Right Apache configs
Aegir user on Aegir server needs keys to get into all servers and run relevant commands
Easy install process
Aegir squeeze backport apt-get - will even get LAMP stack Need mysql: soft requirement, but postgreqsl won't work right now. "Patches welcome!" Also, currently no other CMS deployments supported. "Patches welcome!"
Can manually install on RHEL or using nginx - just trickier
Standalone backend is called Aegir Provision; front end is Aegir Host Manager D6
[Live demo: dpkg configuration fails hard on getting MySQL password prompt wrong]
Working website
Platform = a multisite Drupal [so for monosites Drupal, platform = site]
Uses drush makefiles
Demo of new OpenAtrium install
Demo of upgrade
