2. Agenda
• Relevance of Cloud Orchestration
• Introduction to OpenStack
• OpenStack Logical Architecture
• OpenStack deployment – Challenges
• Introduction to Crowbar
• Deploying OpenStack using Crowbar
3. Flip “80-20%” of IT Spending

Cloudonomics:- Cloud is the Game
changer
4. Promises We made…
• Cloud will
– Lower the TCO
– Enable Activity Based Costing
– Cloud will demonstrate Demand Side EOS

5. OpenStack
• Objective - Delivers a massively scalable cloud operating
system.
• Fastest growing OpenSource Cloud
• More than 180 companies involved with OpenStack
• Dell was one of the first adopters of OpenStack and has a
strong presence in the OpenStack Executive Board
• Dell Crowbar - Industry`s first End to End automated
orchestration tools
6. Typical Challenges in Scale of Operations for Cloud
I/F
• Manages elastic resources
• Embraces constant change
• Productizes best practices
• Plan for hyperscale computing design
• No Premium systems
• No h/w redundancy
• No manual operations
10. Steps to manually install OpenStack
• Review the most supported platforms.
• This installation walk-through goes through a very specific path for installing OpenStack on
Ubuntu 12.04 with root access and specific configuration settings using MySQL for related
databases. Fedora and Ubuntu are the most tested platforms currently.
• Install the Identity Service (Keystone).
• Configure the Identity Service.
• Install the Image Service (Glance).
• Configure the Image Service.
• Install Compute (Nova).
• Review the assumptions made in this installation for Compute.
• Configure Compute with FlatDHCP networking using 192.168.100.0/24 as the fixed range
for our guest VMs on a bridge named br100.
• Create and initialize the Compute database with MySQL.
• Add images.
• (optional) Install OpenStack Object Storage (Swift).
• Install the OpenStack Dashboard.
• Launch the Dashboard.
• Add a keypair through the Dashboard.
• Launch an image through the Dashboard to verify the entire installation.
12. Clouds require an Operational Focus
July 20, 2011
• Clouds demand significant operational
and process controls
Dell Cloud Solutions
SW
• Operational decisions drive hardware
OPS
and software decisions
HW
• We are finding ways to productize
operations into best practices
13. Challenges
• Skilled Personal
• Linux
• Cloud Infrastructure
• OpenStack Architecture
• Bring up Time
• Configure
• Deploy
• Monitor
• Spend time on Using Cloud rather then setting up one
15. What is Crowbar?
Mission: “A Zero Touch Cloud Installer”
July 20, 2011
Servers in boxes to full function cloud in under 2 hours
•Fast & Flexible
Dell Cloud Solutions
•Bare metal install including BIOS & RAID config
•Users can choose how their system is configured (“barclamps”)
•DevOps Embracing
•Ongoing Operations Model (DevOps for Clouds)
•Leverages & Wraps Opscode Chef
•Open
•Dell developed tool
•Not specific to OpenStack – Dell using for other Apps
•Not restricted to Dell hardware
•Apache 2 license 15
16. Crowbar Contd..
• Everything you need in one Image
• OS Image – PXE
• Barclamps – Core
• Crowbar, IPMI, Deployed, Network, Nagios etc…
• Barclamps – OpenStack
• Mysql, Keystone, Swift, Glance, Nova Dashboard, Nova
• Nagios – Monitor server health
• Easy to use - GUI
