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

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
