IaaS CaaS/ VMM • Self-service mgmt of virtual compute.

• Perception of low network & storage relevance

• Simple tenancy model per VM.

• CLM+ESX

• DynamicOps+Vsphere

• Cloupia + XenServer

• MSSC + HyperV

Web2.0 • VM mgmt at scale.

• API-driven compute automation: Spin up and shut down

webservers as load changes

• App dev’t model more efficient

• Load Balancing, segmentation, simple security.

• Tenancy = in theory, infinite.

• OpenStack

• CloudStack

AppInfra • Compute focused Internal cloud solutions

• Often used to scale specific consumer facing apps

PaaS

Service Model Characteristics Example solutions

PaaS No Infra

Apps

• No VM or direct storage view, everything is abstracted

away

• Focus is on scale out.

• MVC: Model View Controller – web app dev’t paradigm

• Model = data store (db)

• Controller = App logic

• View: presentation to the consumer.

• each of the 3 elements scale independently

• Heroku

• CloudFoundry

• AppFog

• EngineYard

Targeted

App

• A platform for developing S/W for you to use rather than

for others to use

• Often focused on an app family (E.g. business

management, gaming infra, etc.)

• Google app engine &

Google apps

• SalesForce

“Force.com”,

• WordPress

SaaS

Service Model Characteristics Example solutions

SaaS Catalog-

driven

• E.g., SP providing SaaS

• Service offers bundled at the application layer

• Deployment automation for tenant scale

• Focus is on managing access to the app

• Parallels

• CCP+rPath+CPO+AS

Unified

Portal

• E.g., Enterprise view.

• Aggregate multiple services

• Single Sign-on management

Hybrid

Service Model Characteristics Example solutions

Hybrid DR/IaaS • Classic multi-DC issues (disk sync, etc.)

• Infrastructure-to-infrastructure synchronization

• VM level view

• Migration possible, but potentially slow (Large VM size

issue)

• vCloud Director, ‘multi-

cloud’ models

App

Mobility,

Data

Mobility

• Suitable for Web 2.0 application models

• MVC or similar app dev’t

• App level view

• Migrate the app rather than the VM

• How do you migrate the Data?

• Real hybrid use case: takes into account application

• private CloudFoundry-

>hosted

CloudFoundry?

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”

DevOps – Development, Deployment, and Operations

Agile/Extreme/Lean/Etc. application

development expect rapid turn from

development->test->production

Model for Deployment built into the

development/test lifecycle

‒ Unit test

‒ Continuous Integration

Move from semi-annual release to

daily or weekly releases

Some iterate ~40x/day dev-

>production!

GIT

A “modern” Source Code Management (SCM) system

Uses a pointer paridigm rather than patch model

Similar but different to RCS/SCCS/CVS/SVN

Biggest end user difference is that branches and merges become easier

Driven by the need for concurrent development of very large projects (Linux

Kernel dev community)

OpenSource DevOps tools

Page 34: BRKAPP-2031

© 2012 Cisco and/or its affiliates. All rights reserved. BRKAPP-2031 Cisco Public 34

Why Git?

OpenStack community selected Git as the repository of record for source, and

specifically github.com (not the owner of Git, just a _VERY_ heavy user)

Git integrates well with many of the development workflows and processes used

in Agile/Extreme/Lean class development processes

Git works well with large distributed teams working on the same codebase

Try it you’ll like it

Simple Puppet

One of the new breed of “DevOps” tools – Data drive Operations

Others include Chef, Ansible, JuJu, etc.

Development driven operationalization of systems

Developers write the app

Developers write the test

Developers write the deployment

Developers write the upgrade

Developers wrote the operational model

Build Process

First, build a build node (often a manual process)

Second, download (clone) the CiscoSystems github repository

Run the install script (modify the default parameters)

Run puppet, configure puppet master, mysql, cobbler

Power-on the rest of the system, let cobbler and puppet work their magic

OpenStack Cisco Edition Demo

‒ Build node (pre-built)

‒ Cobbler bare metal install

‒ Puppet configuration

Page 48: BRKAPP-2031

© 2012 Cisco and/or its affiliates. All rights reserved. BRKAPP-2031 Cisco Public 48

Install the first node (manual)

• Use UCSM or CIMC interface to provide remote KVM and virtual CD

• Mount the ISO, and build the node. Default options, LVM against the local

RAID configuration, OpenSSH installed.

• When build is complete, add base build packages:

‒ apt-get install git puppet ipmitool python-passlib python-jinja2 python-yaml –y

• Get the puppet install and build manifests:

‒ git clone https://github.com/CiscoSystems/folsom-manifests -b multi-node

Page 49: BRKAPP-2031

© 2012 Cisco and/or its affiliates. All rights reserved. BRKAPP-2031 Cisco Public 49

Setup basic parameters

• Copy the folsom-manifests/manifests directory to /etc/puppet/manifests

• Load the puppet modules: /etc/puppet/manifests/puppet-modules.sh

• Edit the site.pp file with the addresses collected earlier

Page 50: BRKAPP-2031

© 2012 Cisco and/or its affiliates. All rights reserved. BRKAPP-2031 Cisco Public 50

Run puppet on the build/puppetmaster node

• puppet apply –v /etc/puppet/manifests/site.pp

• puppet plugin download

• “reset” your environment:

• /etc/puppet/manifests/reset_nodes.sh

• Wait ~15 minutes. Log into your control node:

• ssh localadmin@control or https://control_node_ip

That’s the basics – now for the network

• Leveraging OpenVirtualSwitch for Linux based switching

• Leveraging Linux Iptables for firewall/router

• Using DNSMasq for DHCP and DNS proxy services

• For network, there are two deployment choices

‒ Nova-network, proven, in production

‒ Quantum, lots of testing, still not common in production use

Single Flat or Provider network

55

• Simple model

• Equivalent to nova-network VLAN

• No dhcp, metadata, NAT, etc.

• All tenants/projects see each other

• Router managed by something

other than OS

Page 56: BRKAPP-2031

56 © 2012 Cisco and/or its affiliates. All rights reserved. BRKAPP-2031 Cisco Public

Shared Flat Networks

• Provides a model to

exponse multiple L2

domains to end users

• Can provide some tenante

segregation

• Still no

dhcp,metadata,NAT

56

Mixed Flat and Private Networks

• Private networks (big difference in

this example), provide:

‒ DHCP

‒ metadata

• Shared newtork in this model is as

before

57
