Session presented at the 2nd IndicThreads.com Conference on Cloud Computing held in Pune, India on 3-4 June 2011. http://CloudComputing.IndicThreads.com Abstract: OpenStack is an Initiative by RackSpace and NASA that aims for building an Open cloud platform supported by a vibrant Ecosystem to encourage broad adoption in the market.This is currently a hot favorite of enterprises looking to build an Open cloud. This talk will provide a brief overview of the different OpenStack Modules (Compute and Storage) and explain how to utilize these to build a cloud. We will also explore the newly released Xen Cloud Platform (XCP) and its integration with OpenStack Platform. There will be a hands-on demo (time permitting) where we will show how the integration between the OpenStack Platform and XCP works. Key Takeaways for the audience: 1) Understanding of OpenStack platform. 2) How to get started with OpenStack for building your own cloud. 3) Understanding of XCP 3) How the integration (OpenStack-XCP) is supposed to work 4) What are the opportunities for building different products that add value in the OpenStack Ecosystem Speaker: Amit Naik is an Architect at BMC Software and has 15 years of experience in the IT field with experience in delivering multiple end-to-end projects and Products. Multiple speaking engagements at different venues both in India and Abroad. Experience with blogging, evangelizing etc. Excellent communication and interpersonal skills. Joint Speaker: Prasad Nirantar is a Staff Product Developer at BMC Software. He holds a B.E in Polymer Engineering from the University of Pune and an MS from University of Akron, US. He also holds a diploma in business management from Symbiosis University.

4. Rise of OpenStack – IaaS Enabler
Cloud Services have three main flavors:
• IaaS
• PaaS
• SaaS
For early cloud platforms, IaaS
enablement was the key focus
Help organizations build their own
public, private, or hybrid clouds
4

5. IaaS Enablement Platforms
AKA Cloud Management Platforms,
Cloud Controllers, Fabric Managers,
Cloud Orchestration, IaaS Platforms, etc
Enablement Platforms turn Physical and
Virtual IT assets into elastic cloud entities
Resulting IaaS can provision and manage
Compute, Storage, Networking or other
resources in some combination
5

6. OpenStack Precursor –
Eucalyptus
Eucalyptus was very popular IaaS
Platform, grew out of project at UCSB
25,000 installs and big user community
 NASA used to be one of the big vocal
supporters of Eucalyptus
In May 2010, NASA partnered with
Rackspace to announce a competing effort!

7. Eucalyptus Falters
NASA had two main issues with Eucalyptus
• Scalability of Eucalyptus was insufficient -
Nebula project needed massive scalability
1 million machines & 60 million VMs
• Open Core Vs Open Source –
NASA engineers were unable to contribute
code to some Eucalyptus Modules due to
some parts being closed source
7

8. Nebula Project at NASA

9. Birth of OpenStack: Rackspace+NASA
OpenStack Rackspace+NASA collaboration
Rackspace “Ozone” cloud controller and
NASA “Nova” cloud fabric on Nebula
Rackspace “Cloud Files” storage engine
9

10. Rackspace Motivations
Needed something to counter Amazon’s
rapid pace of innovation
Shift to open source builds rapid
developer mindshare
Focus on their Strengths –
• Customer Support
• Heterogeneity
 Support offerings as new revenue stream
10

12. OpenStack Project Objectives
Mission: Create an ubiquitous open source
cloud computing platform that is simple to
implement and massively scalable
Open - All code is Apache 2 licensed
Simple - Architecture is Modular
Scalable – Massive scale Design Goals:
• 1 Million Physical machines, 60 Million VMs
• Billions of Objects stored
12

13. OpenStack Flavors
OpenStack Compute (Nova) – service to
Provision and Manage millions of VMs
(comparable to Amazon EC2)
OpenStack Storage (Swift) – service to
large-scale, redundant storage of Static
Objects (comparable to Amazon S3)
OpenStack Image Service (Glance) –
service to discover and register virtual
disk images for use with Nova
13

14. OpenStack Release Train
Three quick releases in under a year – Next
release “Diablo” expected in Q3 2011
Diablo focus - Make OpenStack ready for
large-scale deployments
14

15. Architecture of OpenStack
15

16. Architecture of OpenStack
Built on a shared-nothing, messaging-based
architecture using AMPQ based queues
nova-api process is the heart of the
OpenStack Nova – its “Cloud Controller”
• Provides an endpoint for all API queries
• Initiates most of the orchestration activities
• Enforces some policy - mostly quota checks
nova-schedule decides which compute host
a given VM should be created on
16

17. OpenStack Architecture Cont’d
Three Primary Infrastructure Modules
• nova-compute process primarily creates and
terminates virtual machine instances.
• nova-volume manages the creation, attach &
detach of persistent volumes to VMs
• nova-network manipulate the network e.g.
configure VLANs, change iptables rules, etc
SQL DB stores run time state of cloud
infrastructure such as Instances in use,
Networks available, Volumes attached, etc 17

18. OpenStack Component Specifics
Written almost entirely in Python
Available pre-built on Ubuntu and RHEL
RabbitMQ is the AMPQ product of choice
Supports MySQL and PostgreSQL
Libvirt, Xen API used in instance creation
Support for EC2 API and S3 semantics
Supports wide variety of Hypervisors
18

19. OpenStack – Hypervisor Support
Hypervisor agnostic – support for:
• Hyper-V 2008
• KVM - Kernel-based Virtual Machine
• QEMU
• User Mode Linux
• VMWare - ESX/ESXi 4.1 update 1
• Xen - XenServer 5.5
Supports OVF (open virtualization format)
19

20. Competitors and Implementers
 Eucalyptus – Still very popular
 OpenNebula – Used at FermiLabs, CERN
 CloudStack – Cloud.com’s IaaS platform
 CloudForms – Red Hat’s IaaS offering (beta)
OpenStack in the commercial space:
 Ubuntu Enterprise Cloud (UEC) – Switched
from Eucalyptus to OpenStack as base
 Project Oylumpus – Citrix branded OpenStack
 Internap – Rackspace competitor switching 20

21. OpenStack Ecosystem
21

22. OpenStack Partners Ecosystem
Gaps in Stack filled in by Partners:
• Billing - Chargeback and Showback
• Integrated Metering, Capacity Planning
• Full-Spectrum Monitoring, Analytics
• Advanced Networking Capabilities
• Management Systems
• Cisco has come out with a Networking as
a Service (NaaS) Proposal for OpenStack
• Zenoss and CloudKick for monitoring
22

23. Ecosystem-Facebook OpenCompute
Facebook recently open sourced their
proprietary datacenter designs under
OpenCompute project
Puts all the “secret sauce” of their
datacenter and sever design on the web
Collaborating with OpenStack to ensure
seamless deployment on Open Compute
Power savings of 38%, cost savings 24%
23

24. Ecosystem – Xen Cloud Platform
Xen Cloud Platform
Open source platform to build clouds
Virtualization platform including
• Xen hypervisor
• Network and Storage support
Originally derived from XenServer – GPL2
24

25. XCP Architecture
25

26. OpenStack and XCP
OpenStack is hypervisor independent
Designed to work with XenServer & XCP
Xen Cloud Platform (XCP) is the cloud
optimized and Open source version of Xen
OpenStack plays the role of cloud
orchestration platform
XCP to be the virtualization platform
26

27. OpenStack and XCP
 OpenStack supports XCP through XenAPI
XenAPI: Management API exposed by XCP
 OpenStack compute interacts with the XCP
hypervisor (XEN)
27

28. OpenStack Limitations (Cactus)
 Nova codebase = merger of Rackspace &NASA
Cloud controllers – Still Maturing
 Swift code base is mature and Ready for
primetime
 HA, fault tolerance support in Cactus Release is
in proposal stage
 Lack of good documentation on Setup/usage
 “Diablo” Release will be recommended for wide
adoption
28

29. Conclusions
OpenStack is becoming a default open
source cloud fabric in IaaS space
Ecosystem is an excellent opportunity to
contribute to this exciting effort
Wide adoption by Industry heavyweights
guarantees major traction
Lots of room for improvement but fast
release cycles ensure quick fixes
