• Required packages • JDK, WLS, SOA Suite • Patches • Kernel params, users, entropy, etc.
• NM and Domain configuration • NFS share for JCA configuration • Deployment of test composites

SERVER PROVISIONING
7 | x
• Automated installations and rollbacks • Inject environment variables, smoke-testing
• Automated builds, tests, and packaging from version control • Central archiving in repository or artifactory
• Automated provisioning of middleware • High frequency of changes to servers (e.g. patches)
• Automated provisioning of OS-ready images • Low frequency of changes to images

Server provisioning | the traditional way
Artisan server crafting
● Boring
● Stressful
● Error-prone
● Time-consuming
● Non-scalable & expensive

Server provisioning | how it can be
Automated configuration management
● Describe a system once, apply as often as you want
● Automate the repetitive, focus on improvements
and “real” problems
● Predictable results
● (Near) real-time provisioning
● Keep servers in sync
12 | x
Server provisioning | infrastructure as code
Advantages
● Configuration is documentation and always up-to-date
● Configuration is version controlled
● Configurations are defined in a machine- and OS-independent domain
language so the manifests are portable and can be reused
● Change and test configuration, not the server, and re-apply

PUPPET
Introduction to
14 | x
Puppet Example | Apache HTTP Server
package { "httpd":
name => "httpd.x86_64",
ensure => "present",
}
file { "http.conf":
path => "/etc/httpd/conf/httpd.conf",
owner => root,
group => root,
mode => 0644,
source => "puppet:///modules/apache/httpd.conf",
require => Package["httpd"],
}
service { "httpd":
ensure => running,
enable => true,
subscribe => File["http.conf"],
}
● Manifests
● Resources
• Name
• Attributes and
values
● Ordering and
dependencies
15 | x
More on Puppet | building blocks
● Variables and (custom) facts
● Node declarations
● Classes and Modules
● Defined resource types
● Templates
if $operatingsystem == 'CentOS'
node 'www1.example.com' {
include common
include apache
}
node 'db1.example.com' {
include common
include oraclexe
}
file { "http.conf":
path => "/etc/httpd/conf/httpd.conf",
owner => 'root',
group => 'root',
mode => '0644',
content => template('config/httpd.erb'),
}

CHEF

Chef | architecture

Chef | terminology
● Node, Server, Workstation
● Chef-client asks Chef-server about the policy for the node
● Resources: a component and the desired state
● Recipes: describe resources and desired state
● Cookbooks: sets of recipes grouped together, also includes templates
and source files, etc.
● Run List: recipes from cookbooks you want to run
● LWRP: custom actions
23 | x
Example Recipe
paca
Policy says package
should be installed
This service should be
enabled on reboot, and
must be running
Template specifies the
contents required
