What I am going to talk about
§  NOT TALKING about our products
§  Come by the booth if you want to do that
§  Cloud / Mobile Shift
§  CI tools and methodologies
§  Open Source Platforms to support them

Our Lessons
(we are still learning)

What is driving my perspective
§  330MM Systems Integrator
§  550 assoc / 270 engineers
§  Original focus contact center
development
§  Corporate Sponsor of
OpenStack Foundation
§  Current Amazon User (and
reseller) integrating
OpenStack into current
offerings
§  Industry shifting from SI to
Software Dev

What Drives our Perspective

Last nights conversations – interesting note

Industry is shifting

Client server apps – The new mainframe

New way consumers interact with apps

Built Differently
§  40% of mobile apps built on
cloud
§  Constructed of loosely
coupled services
§  Ubiquitous platforms
§  Client provided

How are these built, and what do they run on

10 Deploys a Day – John Allspaw : Flickr
§  Fully tested
§  Fully QA'd
§  Fully
Documented
§  ITIL Compliant
§  Push Button

Building quality into the system
§  Evaluate the system as a
whole, not the components
§  non-automated process is a
theory
§  Tests are as important as
features (BDD)
§  Proper rigor avoids bugs
§  Infrastructure must be
software defined

Classic software development - SDLC
§ SDLC
§ Long release
cycles
§ High bug
counts

Perfect for the Client Server world

SDLC Shops are evolving
§ Agile
§ Sprinting
§ Faster,
better,
stronger

Hi I’m Speed Racer (Agile Developer) I …
Maintain a Single Source Repository.
Automate the Build
Make the Build Self-Testing
Everyone Commits To the Mainline Every Day
Every Commit Should Build the Mainline on an
Integration Machine
Keep the Build Fast
Test in a Clone of the Production Environment
Make it Easy for Anyone to Get the Latest
Executable
Everyone can see what's happening
Automate Deployment

New Tools and Techniques

Tools I’ve fallen in love with - Jenkins

Jenkins Work Flow

New Match – Agile to ITIL

CI/CD creates tension between Dev and IT

ITIL based IT – built to support these apps

Let’s get the love back

What do you do?

Easiest answer – not always an option

IT CAN be as flexible as Development

Mapping IT Ops to Agile Dev

Agile Process Optimization
§  Map IT to Software
Process
§  IT Process Optimization
§  Development / IT Ops Value
Stream Mapping
§  Agile optimization
§  Scaled Scrum
§  Kanban
§  Dev / PMO methodology
optimization
§  Process mapping to
existing ITIL methodologies

Deployment Automation

IT Deployment Automation

Deployment Automation

Tools – Automating Hardware deployment w/ Razor

Integrate this process with IT Operations

But what about the cloud platform?

OpenStack Vision

OpenStack Cloud Operating System

OpenStack Capabilities
Compute
Provision and manage large pools of on-demand
computing resources
Object Storage
Petabytes of reliable storage on standard gear
Block Storage
Volumes on commodity storage gear, and drivers
for more advanced systems like NetApp, Solidﬁre,
and Nexenta
Networking
Software deﬁned networking automation with
pluggable backends
Dashboard
Self-service, role-based web interface for users
and administrators
Shared
Services
Multi-tenant authentication system that ties to
existing stores (e.g. LDAP) and Image Service

Community Developed

Ecosystem Growth

Contributors per month (ohloh)
175 Contributors in the last 30 days

Lines of code (ohloh)
Nearly 600,000 Lines of Code

OpenStack = History in brief
§  NASA Launches Nebula
§  Built by and for Fed Govt
§  Chris Kemp
§  March 2010
§  Rackspace Open Sources
Swift (Cloud File)
§  May 2010
§  NASA Open Sources
virtualization software -
Nova
§  June 2010
§  OpenStack Formed
§  April 2011
§  Quantum is released (lots
of Cisco code)
§  Now – Cooler then
Amazon ;)

Early user examples
§  NASA
§  CIA / NSA
§  JPMorgan Chase
§  RSA WEB
§  Dreamhost – Web Hosting /
Cloud Provider
§  Rackspace.com
§  Cisco Webex
§  Cisco Development –
§  40% cost reduction
§  Cisco CITIES
§  Best Buy

OpenStack Development Ecosystem: 500+

Consolidation
Management
Client / Server apps
Different platforms, Different workloads

OpenStack, CI and Cloud to success
§ Software development
methodologies are
changing
§ Cloud apps require
different platforms and
methodologies
§ IT and Development
can coexist this new
world
