Live Cross-Cloud Migrations With Aeolus and Snap

In the past when evaluating cloud providers, one had to to make a critical decision right up front, to select the provider that offers the features needed at a price that is agreeable to the end-user. If the provider changed their terms of service and/or pricing scheme, the sysadmin/developer was more or less stuck with their choice, unless they made the painful effort of manually migrating all software and data to another provider. Well not anymore.

I'm pleased to announce that with the assistance of Aeolus, Red Hat's Open Source Cloud API, and Snap! a system snapshotter and restoration utility (started as my Masters project in '07), it is now possible to migrate cloud instances of any type across cloud providers (currently supported distros are Fedora, Ubuntu, Debian, RHEL, and CentOS with more and Windows support in development / coming soon).

For details, see the following step-by-step guide complete w/ screenshots of how to migrate instances between Amazon EC2 and Rackspace (this will work for migrating instances between any cloud providers supported by deltacloud, the core Aeolus component/api). Everything will be migrated from the source instance to destination on the fly (no instance downtime), from package repositories and installed software, to files modified outside the package management system, to services and their configurations, etc.

Stay tuned for more updates. To the cloud!
