This is slide deck for talk given by Archipel Project Team, with Nicolas Ochem as speaker. It introduces the concept behind Archipel, a solution to manage and supervise virtual machines based on XMPP.

Is it really
mandatory ?

4. Benefits
• Saves space, time, money and resources
• Green IT
• Simplify exploitation
• Quick platform implementation
You manage virtual computer as an application

5. 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

6. t o d a y ’s
Te c h n o l o g i e s
no Java here

7. XMPP
• Real-time and extensible communication protocol
• Main usage : instant messaging (Google, Facebook etc.)
• Free
• Decentralized

8. Python
• Flexible, powerful, performant and simple
• Cross-platform (Linux/UNIX, Mac OS X et Windows)
• Large components library
• Open source

9. 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

10. Libvirt
• Unified layer to control virtual machines
«Almost» unified
• Support many virtualization engines
KVM, XEN, ESX,VirtualBox, Hyper-V, OpenVZ, LXC...
• Provides a Python library

12. What is exactly Archipel?
• Orchestrator for virtualization
It can be compared to Enomalism, oVirt, Proxmox, etc.
• All is about real time
Everything is pushed, never pulled
• Modular
Near functionality free core and a set of modules
• Scalable
It is as easy to add or remove an hypervisor.
• Open source
No need for further explanation about that

13. Live migration

15. Logical Architecture

16. 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 resource
This way you can know on which hypervisor the vm is hosted
• PubSub for events, admin, roles and more
Push 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-133
User 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

17. Multi-site Architecture
