22. 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 ?

24. CHANGE
Motivations People
• Speed
• Reliability
• Scalability Money Time
Dependency

25. WHAT’S NEXT ?

26. PLAN AND DESIGN YOUR
ARCHITECTURE
Load Balancers
Firewalls
Web Cache
Web Servers
Database Servers

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

28. INTRODUCING
Ruby preferred

29. REDUCE SERVER
DEPLOYMENT TIME TO
5 MINUTES

30. 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”

31. 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

32. 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

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

34. 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

35. 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
Source : https://github.com/opscode/cookbooks

36. 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
Source : https://github.com/opscode/cookbooks

37. CHEF WEB INTERFACE

38. 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

39. 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 => '',
}

40. 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'

41. WEBISTRANO WEB
INTERFACE

42. 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

43. NAGIOS WEB INTERFACE

44. DOES THIS MAKE BUSINESS
SENSE ?

45. 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
