History – Business Drivers
Capacity planning - Involves ensuring that an organization has the right infrastructure, resources and services to support their business and customer base in the future.
Operating Overhead - Reducing the up-front cost of acquiring new IT infrastructure and the on-going cost of owning and maintaining said infrastructure.
Operational Agility - The ability of a business to respond to change by being able to scale its IT resources.
History – Technology Innovations
Grid Computing Technology - Way to provide computing resources on demand and on a pay-as-you go basis.
Clustering Technology - Create a failover system that employs multiple similar IT resources together to provide greater availability and reliability.
Virtualization Technology - Enables physical IT resources to provide multiple virtual images of themselves.
Definition Cloud computing is a specialized form of distributed
computing that introduces utilization models for remotely provisioning scalable and measured IT resources.
Characteristics:
• On-Demand Usage
• Ubiquitous Access
• Multi-tenancy and Resourcing Pooling.
• Elasticity
• Measured Usage
• Resiliency

OpenStack is…
An open source software that allows any company to build their own public or private cloud
Sits above the hypervisor and is hypervisor agnostic KVM, Xen, Hyper-V, ESX, LXC.
Think of it as: “software that powers Amazon’s ECS+S3” Its mission is to produce the ubiquitous open source
cloud computing platform that will meet the needs of public and private cloud providers regardless of size, by being simple to implement and massively scalable.
Conceptual Architecture
Network (Neutron)Provides "network connectivity as a service"
Block Storage (Cinder)Provides persistent block storage to guest VMs
Compute (Nova)Provides virtual servers upon demand.
Dashboard (Horizon)Modular web-based user interface for all services.
Image (Glance)Catalog and repository for virtual disk images.
Object Storage (Swift)Allows you to store or retrieve files.
Identity (Keystone)Authentication and authorization for all services.

Devstack is…
A shell script to build complete OpenStack development environment.
Supports: Ubuntu 12.04 (Precise), Fedora 20 and CentOS/RHEL 6.5( 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)
Who uses Devstack?
Developers working on OpenStack
Used to test changes and verify they work in a running OpenStack deployment
Used by the CI system to test changes as they are pushed to gerrit for review.
Used for demos and proof of concept
