Enterprises are building clouds to...
Where is your enterprise on the path to cloud?
Meet departmental resource needs & timelines
Control & monitor the entire environment

Datacenters are being virtualized, Servers are first
Hypervisors provide abstraction between SW and HW (Servers)
HOST 1 HOST 2 HOST 3 HOST 4, ETC.
VMs
Hypervisor:
Turns 1 server into many “virtual machines” (instances or VMs)
(VMWare ESX, Citrix XEN Server, KVM, Etc.)

Automation & Efficiency
Hardware abstraction for each server Better resource utilization for each server
Compute Pool Network Pool Storage Pool
Virtualized Servers Virtualized Networks Virtualized Storage
Next: Storage, Network…the building blocks
Flexibility, Efficiency are key drivers Resource pools for apps starting to form...

But questions arise as the environment grows...
“VM sprawl” can make things unmanageable very quickly
Where should you provision new VMs? How do you keep track of it all?

Summary – Why OpenStack?
The Cloud Operating
System enables
enterprises to
• Control and automate pools of
resources
• Efficiently allocate resources
• Empower admins & users via self-service
portals
• Empower developers to make
apps cloud-aware via APIs
Top 3 Benefits of a
Common Platform
• Easy to migrate data and
applications to public clouds when
conditions are right
• based on security policies,
economics, and other key business
criteria
• No longer locked in with major
investment in one provider
• Disaster recovery

Automation and Orchestration of IT Resources
December 15, 2014 18
OpenStack is a cloud operating system that controls large pools of
compute, storage, and networking resources throughout a datacenter, all
managed through a dashboard that gives administrators control while
empowering their users to provision resources through a web interface.

DevStack – In Nutshell
DevStack is…
An opinionated script to quickly create an
OpenStack development environment
Supports: Ubuntu 14.04 (Trusty), Fedora 20
and CentOS/RHEL 6.5
– OpenStack also runs and is packaged on other
flavors of Linux such as OpenSUSE and Debian
It can run single and multi-node
environments
DevStack is not…
To be used on a production environment
The exact way you would deploy
OpenStack in production (but it’s close)
DevStack’s mission is…
To provide tools used for installation of central OpenStack services from source (git repository)
suitable for development & operational testing
To demonstrate & document examples of configuring & running services as well as command line
client usage
