Modular Open Source
framework
Written in Python
Modular, with Multiple
Projects
(GUI Portal is a project,
Storage is a project..etc)
Supported by
OpenStack Foundation
(Non Profit)

(Incubated, Integrated, Core)
Vendors provide the

(whenever applicable)
“OpenStack is a collection of open source
software projects that enterprises/service providers
can use to setup and run their cloud compute and
storage infrastructure.”
— docs.openstack.org
4. OpenStack – A very active OpenSource community
OpenStack is by far the most active Opensource
cloud project. Nearly 1,500 developers and 169
organizations worldwide contribute.
Since it’s development is
“out in the open” you can
see who contributes

Targeted for
OpenStack
OpenStack is a framework for providing developers with cloud-style APIs
and tools on top of a choice of virtual infrastructure technologies.
Virtualized
Compute, Network,
Storage
?
Primarily new workloads, or “repatriated” VMs from a public cloud.
Very few Tier-1 workloads.
• Common examples:
• Scale-out SaaS/Web applications, mobile back-ends
• Dev/Build/Test, continuous integration
• Research / batch-processing: data analytics, encoding, simulation, etc.
6. Main OpenStack Projects
• Nova: OpenStack Compute (Similar to Amazon EC2 API)
• Swift : OpenStack Object Store (Similar to Amazon S3)
• Glance : OpenStack Image Store (Similar to Amazon AMI catalog)
• Cinder: OpenStack Block Storage (Similar to Amazon EBS)
• Keystone: OpenStack Identity, (Policy and Authentication service)
• Neutron: OpenStack Networking (Network as a service, routing, switching..etc )
• Horizon: OpenStack Dashboard (GUI interface)
• Heat: OpenStack Orchestration and resource Automation
• Ceilometer: OpenStack Telemetry (Performance monitoring and analytics)

11. Why is perception changing?
11
“Free” Do-it-Yourself Work with Vendor to De-risk
Primary Focus on “Free” Primary Focus on “Developer Innovation”
Hire new team Enable Current Team
• First-hand experience in a lab /
production
• Tales from operator meetups, blogs,
articles, analysts, etc.
Awareness of What Running
OpenStack Really Means
• No longer web-scale shops + SPs who
building out new team of developers to
maintain cloud.
• Have different expectations for
support, etc.
Enterprises are Growing
Percentage of Evaluators
12. Focus on Developer Innovation
12
Businesses increasingly see software as a key differentiator
Automation enables their software developers to deliver software faster + more reliably.
OpenStack is a framework for providing developers with cloud-style APIs and
tools on top of your team’s choice of virtual infrastructure technologies.
Why?
How?
13. Interfaces to interact with OpenStack
1) OpenStack ‘horizon’ dashboard
2) Custom build portals
3) CLI
4) Direct API calls
(OpenStack, EC2, …)
All interfaces actually only ‘translate’
between some Interface and the APIs.
The APIs are in the center of everything

Virtual Networking demos are cool….. Production-grade Virtual Networking is COOLER
And don’t forget about making sure the system is resilient to node failures, doesn’t
cause VM network downtime during upgrade, is easy to troubleshoot….
