WHAT AM I GOING TO TALK
ABOUT ?

• Originallywas going to ﬁll this presentation with
scripts and code since this is a SysAdmin’s favorite
topic

topic

• Realized that all work and no play makes Jack a dull
boy, so I am going to mix and match

topic

• Realized that all work and no play makes Jack a dull
boy, so I am going to mix and match

• Tailoredmore towards the Business and Innovation
side of things but will feature snippets of scripts so
you understand how easy it is to innovate

QUESTIONS TO KEEP IN MIND

• How to decide if you need change in your infrastructure ?

• How do you proceed from there ?

• What are the new innovative ways to make this happen ?

• Current Technologies and how do you evaluate them before
applying ?

• How do I think outside the box ?

CHANGE

Motivations People
• Speed

• Reliability

• Scalability Money Time

Dependency

PLAN AND DESIGN YOUR
ARCHITECTURE

Load Balancers

Firewalls

Web Cache

Web Servers

Database Servers

BUT WAIT, PLANNING AND
DESIGN IS SIMPLE. ITS THE
DEPLOYMENT AND
MAINTENANCE THATS
KILLING US.

INTRODUCING

Ruby preferred

REDUCE SERVER
DEPLOYMENT TIME TO
5 MINUTES

WHAT IS CHEF ?

• Fully
automated conﬁguration management system - Imagine
an API for your entire line of servers

• Ruby powered but has a simple DSL (domain speciﬁc language)

• Scripts are now called “Recipes”

WHAT IS WEBISTRANO ?

• Web UI for managing Capistrano deployments

• Lets
you manage your projects stages like test, staging and
production

• Allows you to do multi-stage and multi-environment scenarios

• Allows you to track user deployment activity

WHAT IS NAGIOS ?

• Infrastructure monitoring and alert system

• Ableto monitor uptime, resource usage, and react accordingly
to perform auto healing

• Ableto integrate easily with Chef to perform auto scaling if
and when required

WE HAVE THE TOOLS, BUT
HOW DO WE USE THEM ?

CHEF
• Chef divides its script into “cookbooks” = container/folder

• Each cookbook has sub-folders :
• recipes

• resources

• attributes

• deﬁnitions

• templates, etc...

• Thishelps keep the scripts consistent, neat, easy to maintain
and share

SAMPLE SCRIPT FOR CHEF
Apache Bare Installation
package "apache2" do
  case node[:platform]
  when "centos","redhat","fedora","suse"
    package_name "httpd"
  when "debian","ubuntu"
    package_name "apache2"
  when "arch"
    package_name "apache"
  end
  action :install
end

SAMPLE SCRIPT FOR CHEF
MySQL Install Bare
include_recipe "mysql::client"

if platform?(%w{debian ubuntu})

  directory "/var/cache/local/preseeding" do
    owner "root"
    group "root"
    mode 0755
    recursive true
  end

package "mysql-server" do
  action :install
end

WEBISTRANO

• In
simple terms, it talks to your revision control system and
deploys the latest revision to the server

• Allows you to rollback revisions in case you broke something

• Allowsyou to deploy and rollback on Staging environments
making it a breeze to update your web apps

SAMPLE SCRIPT FOR
WEBISTRANO
Install Wordpress - Conﬁg
CONFIG = {
:application => 'site_name',
:domain => 'example.com',
:user => 'demo',
:password => nil,
:ssh_port => 12345,
:use_sudo => 'false',
:scm => 'subversion',
:scm_username => 'demosvn',
:scm_password => 'passsvn',
:repository => 'svn://svnrepo.company.com/wordpress_base/',
:base_theme => 'thesis_theme',
:subdirectory_path => '',
}

SAMPLE SCRIPT FOR
WEBISTRANO
Install Wordpress - Deploy
set :deploy_to, "/home/demo/#{application}"
set :deploy_via, :remote_cache
set :copy_exclude, [ '.svn', '.DS_Store', '*.bat', '*.exe', 'Thumbs.db', '*.sh' ]
set :shared_children, %w(log media system conﬁg)

after 'deploy:setup', 'deploy:sync'
after 'deploy:sync', 'deploy:cleanup'

NAGIOS

• Lots
of plugins that are used to monitor and track different
aspects of your infrastructure

• APIallows interaction and “plug and play” interfaces with other
services such as Chef

• Conﬁgurationallows for Dashboard and reporting module to
be customized to show current resources and provides
enough data points for future architecture planning and
reviews

DOES THIS MAKE BUSINESS
SENSE ?

POST - EVALUATION

• Reduced deployment times for scaling up servers from 5-6
hours to 5-10 minutes

• Reduced IT OPEX by 56%

• Allowed for Rapid Testing and Iterations

• Lesser
downtime overall and faster patch deployments and
upgrade cycles
