Aeolus is a project that aims to provide cloud portability and proliferation by hiding individual cloud infrastructure and allowing resources to be remixed. It consists of several component projects including a HA Manager, Conductor, Composer, and Orchestrator. The Conductor manages resource pools and placement across clouds, while the Composer generates cloud-independent images. Aeolus integrates with projects like Apache Deltacloud to provide cross-cloud APIs and abstraction.
