The okeanos approach
 Features:
 Production-quality IaaS cloud
 Everything open source:
Ganeti
by
by
 Persistent VMs
 Commodity Hardware – No SAN, No exotic network hw
 Add plain servers/disks/switches to scale up
 Three clicks to start 1 or 10s of VMs, in 15 secs
 Simple to operate

Storage:
•
Every file is a collection of blocks
•
Content-based addressing for blocks
•
Partial file transfers, deduplication, efficient syncing
•
Independent of storage backend (NFS, RADOS, …)
•
OpenStack Object Storage API plus extensions
•
An integral part of Synnefo
•
- Single store for Files, VM Images
•
- Uses common backend with Archipelago
