Eucalyptus (1.4)
Eucalyptus version 1.4 incorporates several new features and improvements. Most notably, it introduces Walrus, our S3-compatible storage service, as well as a completely revamped virtual network implementation that has proved to be more stable, more efficient, and more flexible than our previous solution. Here is the summary of changes from version 1.3:
- Walrus: an Amazon S3 interface-compatible storage manager. Walrus handles storage of user data as well as filesystem images, kernels, and ramdisks.
- New layer-2 networking subsystem based on software VLANS that no longer depends on VDE
- Added support for elastic IP assignment and security groups using the 'MANAGED' networking mode
- Web-based interface for cloud configuration
- Improved key management
- Image registration and image attribute manipulation
- Instance Metadata service (including userData)
- Kernel and ramdisk registration using standard tools
- Configurable cluster controller scheduling policy (ROUNDROBIN and GREEDY currently supported)
- supports multiple VM types
- Support for new instance control operations:
- Reboot instance
- Get console output
- Various Web interface improvements, including cloud and Walrus configuration and editing of user info
- Various Node Controller improvements, including Walrus support, more robust VM control, and better diagnostics
- Revamped logging throughout, with five debug levels
