Open Source

Applied Now to a Cloud IaaS Platform

web scale cloud computing platform
Web Scale Cloud Computing Platform
  • Customers want to avoid being locked
    • Common platform offered by multiple vendors
    • Standardization of the API
    • Ability of move data and applications
  • Cloud service provider needs
    • Serve many tenants, over thousands of severs
    • Easy to operate
    • Allows provider to focus on support, reliability, availability…
    • Need to be able to differentiate offerings and integrate additional services
open source advantages
Open Source Advantages
  • Leverage the work of a growing community of developers
  • Works across multiple hardware infrastructure
  • Possible to deploy at service providers and on-premise
  • Customized to fit individual needs or to add additional services
what is openstack
What is OpenStack?
  • Originated at NASA, with Rackspace
  • Driven by an open community process
  • Three existing projects:
    • OpenStack Compute
    • OpenStack Image Service
    • Open Object Storage
  • Multiple hypervisors: Xen, KVM, ESXi, Hyper-V
  • Releases:
    • Austin: Oct 2010
    • Bexar: Feb 2011
    • Cactus: April 2011: Current
    • Diablo: scheduled for Sept 2011

OpenStack Compute

(VMs & VM Networks)

OpenStack Image Service

(Image Library & Management)

quantum network service
Quantum – Network Service
  • API gives ability to create interesting network topologies.
    • Example: create multi-tier applications
  • Provide way to connect multiple Openstackservices.
    • Example: Nova VM + Atlas LB on same private network.
  • Open the floodgates to let anyone build services that plug into Openstack networks.
    • Examples: VPN-aaS, firewall-aaS, IDS-aaS.
  • Allows innovation plugins that overcomes common cloud networking problems
    • Example: avoid VLAN limits, provide strong QoS
quantum extensibility
Quantum – Extensibility

Quantum API

API Extensions

  • Quantum Service
  • L2 network abstraction definition and management
  • Device and service attachment framework
  • Does NOT do any actual implementation of abstraction
  • Vendor/User Plug-In
  • Maps abstraction to implementation on physical network
  • Makes all decisions about *how* a network is implemented
  • Can provide additional features through API extensions

Quantum Plug-in API

Open Stack: A Platform for Innovation

“I want to report on my customers SLAs”

“My UI will be easier to use”

“I’ll build in a way to share revenue with my customer’s”

“I need a different VM placement policy”

“I let my customers span multiple clouds”

“I have a much better way to snapshot machine images”
