Transcript of Openstack Global Meetup
Who are these Chaps talking to us ?
● Ritesh Nanda (Cloud Architect at Ericsson responsible for Enterprise Cloud Program/Data Centre Operations).
● Syed Armani (Contributer at OpenStack and Google OpenSource programmes.)
Why these Chaps are here?
● Mainly to talk about OpenStack based clouds, OpenStack Foundation and Quantum.
● Current state and future developments in OpenStack ecosystem.
What is OpenStack ?
OpenStack is Apache of Cloud.
July 2010 OpenStack community established
October 2011Announced plans to launch independent Foundation in 2012
April 2012 19 companies announce support for Foundation; form Drafting Committee
Jan/Feb 2012 Created framework for Foundation as a community
June/July 2012 Drafting committee produces and publishes three rounds of legal documents
July 18, 2012 Final legal documents posted for ratification
Road to the OpenStack Foundation
August 2012 Individual & Gold Director elections; first Board of Directors meeting
Sept 19, 2012 OpenStack Foundation Launch!
It is a software which delivers massively scalable private and public clouds.
OpenStack cloud operating system controls large pools of compute, networking and storage resources throughout a datacenter.
What makes OpenStack ?
Lets break it down :-)
WoooooooooooooT :-/ :-( :'(
Keystone is an authentication framework for OpenStack. It provides the ability to add users to groups (also known as tenants) and to manage permissions between users and groups. Permissions include the ability to launch and terminate instances or to administer everyone’s instance.
Nova is the brain of OpenStack based clouds. It handles launching, networking, maintaining, storage and terminating
of virtual machines. Nova has several sub components.
Subcomponents of Nova
nova-api: Accepts incoming commands to interact with the OpenStack cloud. nova-cert: Manages SSL certificates. nova-compute: Manages the actual virtual machines. nova-consoleauth: Manages authentication for VNC access to the instances. nova-network: Manages the OpenStack network system. nova-objectstore: Provides a very basic object storage system. nova-scheduler: Schedules actions between nova-api and other components. nova-volume: Manages storage volumes for instances to attach and use.
Glance provides a catalogue of images. “Images” in this case can be thought of as a virtual machine template. When launching an instance in OpenStack, you choose a template from Glance, such as Ubuntu 12.04 or Centos 5.8, and then OpenStack creates your instance based on that template.
Swift is a very robust object storage system that can manage petabytes of data spread across several servers.
Horizon is a web-based interface to OpenStack. The OpenStack dashboard provides administrators and users a graphical interface to access, provision and automate cloud-based resources. The extensible design makes it easy to plug in and expose third party products and services, such as billing, monitoring and additional management tools.

● A compute agent runs on each compute node and polls for resource utilization statistics. There may be other types of agents in the future.
● A central agent runs on a central management server to poll for resource utilization statistics for resources not tied to instances or compute nodes.
● A collector runs on one or more central management servers to monitor the message queues (for notifications and for metering data coming from the agent).
● Notification messages are processed and turned into metering messages and sent back out onto the message bus using the appropriate topic. Metering messages are written to the data store without modification.
● A data store is a database capable of handling concurrent writes (from one or more collector instances) and reads (from the API server).
● An API server runs on one or more central management servers to provide access to the data from the data store.
Quantum is an OpenStack project to provide "network connectivity as a service" between interface devices (e.g., vNICs) managed by other OpenStack services (e.g., nova).
Why OpenStack felt the need of Quantum ?
Network as a Service in OpenStack
Why Network as a Service
Virtualization : It’s in the network too!Server Don’t sleep at night but Application and
Network as a Service
Multiple network per tenantMultiple network interfaces per VMAbility to connect networks to VM network

Seriously, Why Quantum !
Give Cloud tenants an APIDefine rich network Topologies Leverage different network Virtualization

What they say about Quantum
Quantum to provide network connectivity as a Service b/w interfaces devices (eg-Vnics) managed by other Openstack Services e.g.(nova) Source:wiki.openstack.org/Quantum
Provides a “building Block ” for Sophisticated cloud network topologies
@danwendlandt@PTL for Quantum
What does Quantum Provides
Decouples “logical”(tenant) view of the network from “physical (provider) View.
Simple APIs for Creating and managing virtual networks

What Melange Provides
• IPAM Service IP address management• Enable network block subdivision• VM discovery/auto-assignment• Consumer of IPAM services are expected to be
other Openstack Services i.e. LBaas etc.• Private (overlapping) address space i.e. VPN• Store ip address, gateway, subnet, DNS, NTP
etc.• Floating IP support.
DEMO OF QUANTUM
OpenStack is the future of open clouds. They say that OpenStack is kernel for cloud operating systems. It fits very well for Private, Public and Hybrid cloud. Enterprises like HP and IBM have started adapting to provide enterprise services based on top of OpenStack.
