The great thing about my job is that I get to have fun exploring a lot
of new things…

….and I get to help build a LOT of clouds.

Today’s workshop won’t be overly formal….

7. © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 7
…because I tend to get excited by this stuff.

“OpenStack is a global collaboration of developers and cloud computing
technologists producing the ubiquitous open source cloud computing
platform for public and private clouds. The project aims to deliver
solutions for all types of clouds by being simple to implement, massively
scalable, and feature rich. The technology consists of a series of
interrelated projects delivering various components for a cloud
infrastructure solution.”
-- openstack.org
Basically, it’s software to run cloud
services—including compute, network,
storage, and security—and the
community behind that software.

…but a rising tide that lifts all boats is a mighty hard proposition to
resist for most companies.

“The days of OpenStack being just about Cloud
are over. OpenStack has become a platform for
all manor of changes that are shaking up the tech
industry.”

(that’s AT&T AVP Toby Ford
telling 4500 people why he
thinks OpenStack is the
platform for NFV a few
months ago in Atlanta)
(and that’s a Red Hat senior principal engineer and the Chief Scientist at Brocade
immediately reacting to it.)

• A “cloud computing fabric controller”.
• Basically, it’s what takes care of launching VM instances (think
Amazon EC2).
• Abstracts hypervisors and hardware pools.
• Most operations can be invoked with a REST API call, a CLI
client, or clicking in Horizon (the OpenStack GUI).
• A few features:
• Multiple hypervisors
• Multiple network models
• Distributed and asynchronous architecture
• Security groups
• Resource isolation for large deployments via cell architecture

29. © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 29
• Houses images that can be launched as instances

• Multiple storage backends
• File, Swift, Ceph, etc
• Multiple container formats
• Bare, OVF, AKI, ARI, AMI
• Multiple disk formats
• Qcow2, raw, VHD, AKI/ARI/AMI, ISO, VDI, VMDK

30. © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 30
• Provides a central service for authentication and authorization as
well as service catalog (e.g. where API endpoints are).
• Provides management of auth tokens passed in API calls as
various components interoperate.
• Provides an abstraction layer above various auth backends such
as LDAP or Active Directory.

31. © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 31
• Provides persistent block storage CRUD and
attachment/detachment from instances and snapshotting.
• Similar in some respects to Amazon EBS.
• Abstracts several underlying block storage components.
• Coraid, EMC, NetApp, IBM, LVM, Nexenta, NFS, Ceph RBD, SolidFire
• Originally part of OpenStack Nova, but split out into it’s own
service in the Folsom release.

32. © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 32
• Provides highly available, distributed, eventually consistent object
storage.
• Can be run completely independently of OpenStack Compute.
• Often run on bare metal.
• Similar in many respects to Hadoop HDFS and Amazon S3.
• Replicates objects over multiple machines (usually 3).
• Works best when hypervisor doesn’t bottleneck disk I/O.
• Full API access/manipulation of objects

33. © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 33
• Provides “networking as a service” for OpenStack
• Designed to be capable of running independently of OpenStack
• oVirt has done work to use Neutron for a connectivity service
• Cloudstack has explored the possibility of using Neutron as well
• Is still evolving rapidly
• First (incubated) release: Diablo
• First (core) release: Essex
• First release with L3 functionality: Folsom
• First release with LBaaS functionality: Grizzly
• Now has LBaaS, VPNaaS, FWaaS services, NFV subteams, a Group
Based Policy blueprint, an IPv6 subteam, and work commencing on Virtual
Distributed Routers

34. © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 34
• Provides usage and performance data for OpenStack
• Initially designed with an eye toward billing, now provides broader
insight
• oVirt has done work to use Quantum for a connectivity service
• Cloudstack has been exploring the possibility of using Quantum as well
• Is relatively young
• Still has some blind spots
• Extensible…relatively easy to add new meters in most cases
• Handles a *lot* of data
• Design goal: be able to share collected data with a variety of data
consumers

35. © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 35
• Orchestrates ability to launch multiple composite clouds apps
based on templates that can be treated like code.
• Templates have native format, but can use AWS CloudFormation
format too
• Frequently used for autoscaling services
• Primarily manages infrastructure, but integrates with tools like
Puppet and Chef

36. © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 36
• Provides database services on demand with an elastic, API-
driven interface in a multitenant environment
• Developers don’t have to care what the backend is or where it is
• Developers don’t have to go through tedious setup process

37. © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 37
• Hadoop (or Spark) as-a-service (think similar to Amazon Elastic
MapReduce)
• Simple, on demand provisioning of Hadoop clusters
• Different distributions of Hadoop available on the backend
• Can be managed via API or Horizon
• Offers integration with management tools like Ambari or Cloudera
Management Console

• It’s a bash script.
• It installs OpenStack from the latest version in trunk on a single
(or multiple) node.
• Used by developers to quickly get an environment in which they
can work on features or bugfixes.
• Not a good way to deploy in production, but useful for getting your
feet wet.
• Arvind Somya and Kyle Mestery did a demo and presentation of
DevStack recently for the Triangle OpenStack Meetup a while
back. Say, who’s Arvind? Well…

• A hypervisor
• Except when you don’t.
• KVM and Xen are the best supported today. Hyper-V, QEMU, LXC, VMware also work.
See hypervisor comparison.
• A database
• Most use MySQL, but PostgreSQL and others also work since most code uses the
SQLAlchemy ORM layer.
• Used for persisting operational data.
• A message queue
• Most use RabbitMQ, some use Qpid and ZeroMQ works in some components as well.
• Used for fast interprocess communications (ex: nova scheduler talking to nova network
controller)
• Hardware
• Pools of servers, memory, cpu, disk
• Python Stuff
• Most components run under Python 2.6+
• A few major libraries: Django, Eventlet, SQL Alchemy, many more

• Putting your best foot forward means putting your code
where your mouth is.
Ideas are more readily accepted when there’s effort to back them up.

42. © 2010 Cisco and/or its affiliates. All rights reserved. Cisco Confidential 42
• Don’t be intimidated.
• HolycrapthingsmovereallyreallyfastinOpenStack
• Jump in feet first: be agile and flexible.
• This is going to feel a little different for some of you.
