6. Silos in the business
5
Lack of feedback
between customers and
the business leading to
unclear requirements
CHALLENGES
Upgrade risk due to
managing multiple
application configurations
and versions across servers
Slow deployment
to test environments
leave teams waiting and
unproductive
CHALLENGES
Operations/
Production
Development/
Test
Customers
Business
Owners
Lack of visibility
and governance,
difficult to understand
impact of a change
7. Deliver better products, faster, and at lower cost
Capability for continuous software delivery that enables clients to seize market
opportunities and reduce time to customer feedback
66
Continuous Innovation, Feedback and Improvements
DevOps Lifecycle
Operations/
Production
Development/
TestCustomers
Business
Owners
Accelerate Software Delivery by enabling collaboration
Balance speed, cost, quality and risk by automating & eliminating waste
Speed up the customer feedback loop by delivering small changes, rapidly
What is DevOps?
8. 7
Optimizing the software delivery pipeline
• Reduce time to market
• Improve quality
• Decrease costs

27. Chef Solves This Problem
• But you already
guessed that, didn’t
you?
26
28. Chef is Infrastructure as Code
• Programmatically
provision and configure
components
• Treat like any other code
base
• Reconstruct business
from code repository,
data backup, and
compute resources
http://www.flickr.com/photos/louisb/455529518
7/
27
29. Configuration Code
• Chef ensures each Node complies with the policy
• Policy is determined by the configurations in each
Node’s run list
• Reduce management complexity through abstraction
• Store the configuration of your infrastructure in
version control
28
30. Declarative Interface to Resources
• You define the policy in your Chef configuration
• Your policy states what state each resource should
be in, but not how to get there
• Chef-client will pull the policy from the Chef Server
and enforce the policy on the Node
29
32. Environments Define Policy
• Environments may include data attributes necessary
for configuring your infrastructure, e.g.
• The URL of your payment service’s API
• The location of your package repository
• The version of the Chef configuration files that
should be used
31
35. Nodes
• Nodes represent the servers in your infrastructure
• Could be physical servers or virtual servers
• May represent hardware that you own or compute
instances in a public or private cloud
• Could also be network hardware - switches, routers,
etc
34
36. Node
• Each Node will
• Belong to one Organization
• Belong to one Environment
• Have zero or more Roles
35
37. Nodes Adhere to Policy
• The chef-client application runs on each node, which
• Gathers the current system configuration of the
node
• Downloads the desired system configuration
policies from the Chef server for that node
• Configures the node such that it adheres to those
policies
36
38. Resources
• A Resource represents a piece of the system and its
desired state
• A package that should be installed
• A service that should be running
• A file that should be generated
• A cron job that should be configured
• A user that should be managed
• and more
37
39. Resources in Recipes
• Resources are the fundamental building blocks of
Chef configuration
• Resources are gathered into Recipes
• Recipes ensure the system is in the desired state
38
40. Recipes
• Configuration files that describe resources and their
desired state
• Recipes can:
• Install and configure software components
• Manage files
• Deploy applications
• Execute other recipes
• and more
39
41. Example Recipe
package "apache2"
template "/etc/apache2/apache2.conf" do
source "apache2.conf.erb"
owner "root"
group "root"
mode "0644"
variables(:allow_override => "All")
notifies :reload, "service[apache2]"
end
service "apache2" do
action [:enable,:start]
supports :reload => true
end
40
42. Cookbooks
• Recipes are stored in
Cookbooks
• Cookbooks contain recipes,
templates, files, custom
resources, etc
• Code re-use and modularity
