Stand-alone Server Virtualized Server

‣ Cooling reduce

‣ Fast provisioning

‣ Resource consolidation

‣ Reduced Data Center TCO

‣ Increased ROI of projects

Architecture

Authorization service

‣ Defines the polices to system access

‣ Each profile has a specific dashboard to:

‣ Physical resources management

‣ Business resources management

‣ Network resources management

‣ VM administration segmented per project

User requests

‣ Sync calls are used to get informations about:

‣ VMs and Hosts

‣ RRDs to create the performance graphs

‣ Async calls are used to request actions like:

‣ VM creation, shutdown, start, stop

‣ Add host and pool creation

‣ Interact with NetAPI to set LBs and Switches

Queuing engine

‣ Used to async processes

‣ The subscribers work in paralleling process to instance resources in the cloud

‣ The users receive real-time information about the queue consumption

‣ The users can manage the queue stopping, resuming and removing tasks

NetworkAPI

‣ Used to manage network physical resources

‣ Include VLANs in the switch port trunk

‣ Apply ACLs

‣ VIP and reals creation

‣ Maintain the relationship between server and switch ports

‣ Pluggable and vendor agnostic

XAPI Integration

‣ Layer to contact XCP servers

‣ Expose a VNC proxy with SSL and dynamic token authentication to hosts and VMs consoles

‣ Translates all rest-full calls to XML-RPC using xenapi.py

Roadmap

‣ Multi-datacenter support

‣ Integrate with OpenStack project

‣ Expose an API to integrate with internal PaaS and Data Center management system (Energy, Cooling, etc)

‣ Multi storage repository support

‣ Dynamic live-migration and host shutdown/start based in consumption

XCP evolution

‣ Better velocity in XAPI requests

‣ Today, doing many requests in a pool, the performance is harmed

‣ Pool ejection without restart the Host

‣ Inter-pool migration and storage repository shared between pools

‣ Link the object uuid to the task in an async call (need a new field to connect the objects)

‣ Ex: Async.VM.clean_shutdown(vm)

‣ In this case, the task for the async call, has a field with the Vm uuid

‣ Master recover decision enabled in XCP

Open Source

‣ All components used in project orquestra are open source

‣ After executing the roadmap, migrate the project to OpenStack and turn it open source

‣ Help the OpenStack project with our development force
