Business Track presented by Animesh Singh, Lead Architect and Strategist at IBM. Bring the world's best IaaS to the world's best PaaS, In this talk IBM and Rackspace are going to share their experiences of running Cloud Foundry on OpenStack. The talk will focus on how CloudFoundry and OpenStack complement each other, how they technically integrate using Cloud provider interface (CPI), how could we automate OpenStack setup for Cloud Foundry deployments, and what are some of the best practices for configuring a scalable environment.

What Is OpenStack
• Open Source Project for with a very large community
• Open source cloud computing platform for public and private clouds
• IaaS for managing compute, storage, and networking resource
• Standard and massively scalable cloud operating system

3. 3
Who Is OpenStack
• Founded by Rackspace and NASA in 2010
• Open Source global community of developers, testers, operators, and users

4. 4
OpenStack Community
76K Commits
2000 Developers
38K Tickets
55K Mail Messages
… and counting!

5. 5
OpenStack Architecture
Collection of well integrated projects:
• Compute (Nova)
• Networking (Neutron)
• Object Storage (Swift)
• Block Storage (Cinder)
• Identity(Keystone)
• Image Service (Glance)
• Dashboard (Horizon)
…and others

6. 6
OpenStack Compute (Nova)
Compute is a cloud computing fabric controller, the main part of an IaaS system.
• Component based architecture: Quickly add new behaviors
• Highly available: Scale to very serious workloads
• Fault-Tolerant: Isolated processes avoid cascading failures
• Recoverable: Failures should be easy to diagnose, debug, and rectify
• Open Standards: Be a reference implementation for a community-driven api
• API Compatibility: Nova strives to provide API-compatible with popular systems like
Amazon EC2

7. 7
OpenStack Networking (Neutron)
Network connectivity as a service, a system for managing networks and IP
addresses.
Advantages of software defined networking. Create and manage:
• Networks and subnets
• Routers
• Load balancers
• Gateways
• Floating IPs

8. 8
OpenStack Block Storage (Cinder)
OpenStack Block Storage (Cinder) provides persistent block-level storage devices
for use with OpenStack compute instances.
• Fully integrated with Compute and Dashboard components
• Allows users to manage their own storage needs
• Appropriate for performance sensitive scenarios:
• database storage
• expandable file systems
• providing a server with access to raw block level storage
• Snapshot management provides for volume/data backup and restoration

9. 9
OpenStack Dashboard
Horizon is the canonical implementation of OpenStack’s Dashboard, which provides a
web based user interface to OpenStack services including Nova, Swift, Keystone, etc.

10. 10
Along with Rackspace, IBM is also working to accelerate
OpenStack Foundation success…
 Contributions across all releases
 Contributions to the latest Icehouse
release

Why Cloud Foundry?
Meets Developer’s Needs
Focus on app development,
not provisioning VMs,
databases, messaging servers,
etc
Agile development model
Deploy and scale in seconds
Open Cloud Platform
There is an increasing appetite
for cloud-based mobile, social
and analytics applications from
line-of-business executives -
drives the need for a more open
cloud development platform
Compelling Community
Cloud Foundry has a compelling
community and emerging ecosystem
as well as a mature set of
capabilities and robustness

Automate (Leverage the power of community) !

17. 17
Leverage the power of Open Source Community
• Open technologies give us a tremendous amount of power and flexibility to integrate them together
seamlessly
• Lets see some of the examples of what we can do with the power of Open technologies to go from
bare metal hardware to a deployed Cloud Foundry ready to push apps
Open Source for Cloud Foundry and OpenStack
Automation!

18. 18
OpenStack Installation:
• Leverage the open source Chef Cloud infrastructure Automation framework
• Requires information about hardware, network environment and software repositories.
• Automate OpenStack installation in approximately 45 minutes
