Looking Back

Do You Remember What This Guy Did to IT?

The Internet

How will you build your cloud?

The Internet was built on Open Source Software


Welcome to OpenStack

The Cloud needs an Open Source platform to achieve Internet Scale:


OpenStack: A Brief History

nebula.nasa.gov

NASA Launches Nebula

– One of the first cloud computing platforms built by the Federal Government for the Federal Government

March 2010: Rackspace Open Sources Cloud Files software, aka Swift

May 2010: NASA open sources compute software, aka “Nova”

June 2010: OpenStack is formed

July 2010: The inaugural Design Summit


OpenStack Community

OpenStack Introduction

A Cloud Platform

– A collection of interrelated software components delivering capabilities to build and manage cloud infrastructure.

A global community of developers devoted to innovation and openness

Flexibility in deployment and features

Standards for broad deployment

No fear of vendor “lock-in”


OpenStack Terminology

Instance- Running virtual machine

Image- Non-running virtual machine, multiple formats (AMI, OVF, etc.)

Application Programming Interface (API)- Interface for computer programs

Message Queue- Acts as a hub for passing messages between daemons

Volume- Provides persistent block storage to instances

Project- aka Tenants, provides logical separation among cloud users

Flavors- Pre-created bundles of compute resources

Fixed IP- Associated to an instance on start-up, internal only

Floating IP- Public facing IP address


OpenStack Core Projects

OpenStack Compute (Nova) Software to provision virtual machines on standard server hardware at massive scale

OpenStack Object Storage (Swift) Software to reliably store billions of objects distributed across standard server hardware

OpenStack Image Service (Glance) Services for discovering, registering, and retrieving virtual machine images


OpenStack Core Projects Cont..

OpenStack Dashboard (Horizon) A self-service web portal to allow administrators and users to manage OpenStack resources

OpenStack Identity (Keystone) Provides “unified authentication” across all OpenStack projects and integrates with 3rd party authentication systems


OpenStack Incubation Projects

OpenStack Network Information Management (Melange) Intended to provide centralized network information management

OpenStack Network Service (Quantum) Provides “network connectivity as a service” between devices managed by other OpenStack services

Many Other Community Projects http://openstack.org/projects/


Identity Service (Keystone) Introduction

An authentication and authorization (AA) system

Organized into a group of internal services

Provides a HTTP front-end to clients (components, users, etc.)

Support for multiple back-ends

– Allows Keystone to adapt to a wide-range of environments

Provides services for discovering, registering, and retrieving virtual machine images

Images can be stored in a variety of locations

Compute Service (Nova) Introduction

Primary component of the OpenStack IaaS platform

Shared-nothing and modular software architecture

– Services communicate using a message queue (AMQP)

Uses a SQL-based database for storing information

– Shared by all system components

Object Store Service (Swift) Introduction

Object-based storage system

– NOT a block-based system like iSCSI

– Consists of flexibly-sized data containers (objects)

Distributed architecture

– Avoids a single point of failure

– Massively scalable (billions of objects and PB’s of data)

Server hard drives turn into a pool of storage

The Ring

– Mapping between entities and physical location

Proxy Server

– Ties together end users and the Swift back-end services, provides public API endpoint.

Object Server

– Simple blob storage server to store, retrieve, and delete objects on local disk

Container Server

– Lists objects

Account Server

– Similar to container, but lists containers

OpenStack Networking Options

Flat Mode All Instances are attached to a single Linux bridge. IP’s are injected into image on launch

FlatDHCP Mode Similar to Flat Mode, but includes a DHCP server to manage instance IP’s. Instances receive an IP through a dhcpdiscover message

VLAN Network Mode A VLAN, Fixed IP Subnet, and Linux bridge per tenant.

Quantum Network Manager A peer OpenStack service providing network connectivity services

– Current networking under Nova is limited

– Provide tenants an API to build rich networking topologies

– Foster innovation through plug-ins

Provides abstractions, functions, and API for:

– Virtual Network (VN)

– Virtual port (VPT) on a VN

– Attaching/detaching vNIC’s
