OpenStack is an open-source Infrastructure as a Service (IaaS) platform that abstracts hardware into a pool of services, allowing users to deploy and manage applications without managing the underlying infrastructure. It has evolved into a significant player in cloud innovation, supported by a large developer community and organizations such as Best Buy and PayPal. OpenStack offers a user-friendly self-service portal for managing cloud resources and is suitable for various organizations, including universities and banks, seeking to establish private or public cloud solutions.

By the end of this session…
You would have known…
• Some basics of IaaS cloud to begin with
• Why has OpenStack become a sensation in today’s IaaS cloud
space?
• Architecture of OpenStack
• Who should be using OpenStack? What’s in it for you?
• The next generation of technologies - What are the businesses
doing with it?
• How can one contribute to OpenStack?

4. Cloud Service Model

5. Infrastructure as a Service (IaaS)
• Abstracts hardware (server, storage, and network
infrastructure) into a pool capabilities that are delivered as
services
• Consumer is able to deploy and run software such as
operating systems and applications.
• Consumer does not have to manage or control the underlying
cloud physical infrastructure

6. Different IaaS Clouds
• Public Cloud - made available to the
general public or a large industry group
and is owned by an organization selling
cloud services
• Private Cloud - The cloud infrastructure
is operated solely for an organization
• Hosted Private Cloud - Externally
hosted (off premises), and externally
managed by a third-party (such as
IBM)
• Hybrid cloud – a combination of public
and private clouds

7. What is expected from an IaaS Solution
• Services provided –
– Virtual Server provisioning, scheduling and monitoring
– Cloud Storage
– Simplify networks
• Critical Metrics
Virtual server
availability
Time to
provision
Licensing costs for
virtualization &
maintenance
Interoperability
& scalability

8. New applications and IT are being built for Cloud
Legacy workloads: design infrastructure to
support applications
•Virtualization management focal point
•Scale-up compute
•Storage network
•Shared, high function disk arrays
New workloads (Mobile, Social, Analytic, Big
Data): design applications to leverage infrastructure
•Cloud management focal point
•Infrastructure as a Service
•Standard hardware building blocks
Existing infrastructure for
legacy workloads
New infrastructure for cloud
workloads

9. OpenStack

10. Growing day by day
• Major private cloud users at Best Buy, Bloomberg, Comcast,
Fidelity, PayPal and more
• OpenStack has become the center of cloud innovation – more
than 1,000 developers, supported by major IT companies

11. OpenStack - The cloud operating system
• Is community developed, open source
cloud software
• Is an Infrastructure as a Service (IaaS)
platform
• Is open cloud APIs for portable cloud
applications
• Is not a cloud by itself
• Does not include installers, online
updates, tools, documentation and
support from a trusted vendor
• Does not include its own virtual
infrastructure
• Is not perfect – yet! It’s designed to be
extended

12. Development Model of OpenStack
• Identity Service (Keystone)
• Image Service (Glance)
• Telemetry (Ceilometer)
• Orchestration (Heat)
Is a series of interrelated projects
• Compute (Nova)
• Object Storage (Swift)
• Block Storage (Cinder)
• Networking (Neutron)
• Dashboard (Horizon)

13. OpenStack Architecture

14. What does OpenStack offer
• Easy to deploy, simple to use cloud management software
offering
• Self-service portal for workload provisioning, virtual image
management, and monitoring

15. Who should be using OpenStack?
• Universities
• Organization having their own infrastructure such as Banks,
telecom industries, insurance companies etc.
• Organizations who want a easily available application test bed
• Organizations offering public cloud solutions such as IBM
Softlayer, Amazon etc.
• ….

22. Summary
• Infrastructure as a Service Clouds abstract the underlying physical hardware and
provide them as services in form pool capabilities.
• OpenStack is the Open Source IaaS Platform for the Enterprise that will meet the
needs of public and private cloud providers regardless of the size, by being simple to
invent and massively scalable.
• Started by Rackspace and NASA in 2010. Became a Fastest Growing Global Open
Source Community by 2014
• It’s a series of interrelated projects and Does not include installers, online updates or
service contracts by a trusted brand.

monitoring and security
• Contributors of OpenStack have developed solutions on top of OpenStack such as IBM
Cloud Manager, RHEL Openstack platform etc.
• OpenStack has brought value to several new generation technologies.
• It can be used by anyone needing to set up a private or public cloud such as
universities, banks, insurance companies, IBM Softlayer public cloud etc.
