Benefits
• Saves space, time, money and resources• Green IT• Simplify exploitation• Quick platform implementation
You manage virtual computer as an application
The risks of virtualization
• By definition, a virtual server doesn’t exist• A host crashes, a dozen of virtual machines crash• Need some virtual buttons and controls• Need feedback about health of virtual machines and hosts
Need to communicate
XMPP
• Real-time and extensible communication protocol• Main usage : instant messaging (Google, Facebook etc.)• Free• Decentralized
Python
• Flexible, powerful, performant and simple• Cross-platform (Linux/UNIX, Mac OS X et Windows)• Large components library• Open source
Cappuccino / Objective-J
• Cocoa for Javascript, right from your browser• Allow to build powerful web application• Abstraction of underlaying javascript code• Very good performance• Open source
Libvirt
• Unified layer to control virtual machines«Almost» unified
• Support many virtualization enginesKVM, XEN, ESX, VirtualBox, Hyper-V, OpenVZ, LXC...
• Provides a Python library
What is exactly Archipel?
• Orchestrator for virtualizationIt can be compared to Enomalism, oVirt, Proxmox, etc.
• All is about real time Everything is pushed, never pulled
• ModularNear functionality free core and a set of modules
• ScalableIt is as easy to add or remove an hypervisor.
• Open source No need for further explanation about that

Features overview ?
XEP used in Archipel with• Every part of Archipel has it’s own JID and vCard
Hypervisors, Virtual Machines, the users (through the UI)vCards are used to store entity type / custom informations
• Virtual Machines use hypervisor node JID as resourceThis way you can know on which hypervisor the vm is hosted
• PubSub for events, admin, roles and morePush mechanism to trigger actions on UI or agents.
• UI settings are stored using XEP-0049 (private xml storage)And shared between UI sessions for different users
• Service management is done through XEP-133User management from the UI, except admin-list witch is done through XEP-0050 when we have to deal with ejabberd ACLs
• XML-RPC for Shared Roster Group Management (EJAB-1485)Auto-group for hypervisor and vms (no need to ask subscription for everyone) SRG management from the UI
