Commercial solutions
Hypervisor license - depends on CPU and/or memory
Orchestrator license - live migration, HA, backup, …
Certified hardware – limited hardware supported
Centralized storage system – needed for HA

Our Open solution
Open hypervisorit comes with Linux kernel in standard distro
Orchestratorlive migration, ha, backup, … intuitive and web based
Commodity hardwareonly very low requirements needed
No centralized storage systemspecial network filesystem is used instead physical storage

Open hypervisor
Freely available: on your GNU/Linux distribution;
Enterprise-ready: powerful mix of enterprise features and a rich set of partners.
Support: widest range of hardware without hassles (Thanks Linux!)
High-performance: top-level virtualization benchmarks for Windows and Linux workloads.

Open VM management software
OpenNebula Adaptable: highly modular. Proven: massive scale production
environments; Interoperable: XML-RPC, EC2, OCCI
Proxmox Easy to deploy: ISO installer or from bare
Debian Easy to use: centralized web management

Low-end hardware requirements
The simplest virtualization host is... your laptop: CPU with virtualization extensions; A bunch of available memory A bunch of available disk space
Use your workstations to prepare VM before starting them in production.

Focus on storage
Shared storage is not an option for live migration and High-Availability.
A good storage solution: Availability: the sky should not fall on our heads; Scalability: we add new bricks when needed; Price.
Common choice is to use a dedicated NAS/SAN (NetApp, EMC, QNAP and so on).

Our choice: GlusterFS
GlusterFS is an open source distributed network filesystem.
How it works? Aggregate available disk space on your
hosts; Replicate data: HA and prevent data-loss; Data available via LAN with standard
protocols: FUSE, NFS, CIFS.

GlusterFS advantages
Scalability: to Petabytes and beyond! Affordability: use commodity hardware; Flexibility: deploy in any environment; Linear performances: no degradation; HA: replicate data on multiple places; Unified namespace: like a folder on a
local disk
