Git version controls PuppetConfigurations & Cloud Deployments (Yes! Version Controlled Infrastructure)

Git hooksPre-update => puppet syntax checks(puppet parser, puppet lint)Post-update => sync with regional puppet masters

PuppetGit branches => Puppet environmentsSingle puppet master => Test Dev Productionmanifests and files/data => Separate git repoPuppet masters per AWS regionsHiera: a pluggable hierarchical data store

Why Fog?

Cross service compatibility(multitude of services=> Storage, Compute, DNS…)Avoid vendor lock-in(Vendor independent=>EC2, Rackspace, Slicehost, Linode…)Power of Ruby

gem install fog

require ‘fog’

~/.fog

Fog quick starter kitLook at the test suites (thanks to TDD)https://github.com/fog/fog/blob/master/tests/aws/requests/compute/instance_tests.rb

Fog command line[root@zebra ~]$ less ~/.fog[root@zebra ~]$ fog testaws Welcome to fog interactive! :testaws provides AWS>>

ec2 = Fog::Compute.new( provider: "AWS", aws_access_key_id: "KEY", aws_secret_access_key: "SECRET")rsc = Fog::Compute.new( provider: "Rackspace", rackspace_api_key: "KEY", rackspace_username: "SECRET")ec2.servers.create( flavor_id: "c1.medium", image_id: "ami-6936fb00", # Ubuntu 10.04 LTS key_name: "mykeyname", groups: ["default"],)rsc.servers.create( flavor_id: 5, # 4GB Memory image_id: 49, # Ubuntu 10.04 LTS name: my_server_name)

Open Source Fog alternatives libcloud (Python) jclouds (Java) deltacloud (Ruby)

Why Ruby?

“Ruby is designed for programmer productivity and fun” Matsumoto(creator of the ruby language)

everything-ruby by Ajey Gorehttp://confreaks.com/videos/921-rubyconfindia2012-everything-ruby

irb is your friend (ruby interactive shell)root@zebra:~/$ irb1.9.3-p125 :001 > irb alternative = > pry (gem install pry)

The Layers of Abstraction...

Fog => Cloud abstraction

Puppet => OS abstraction

Notes to self >>

Start small...

...and iterate reiterate & re reiterate

Select right tools(Plenty of tools => Puppet/Chef/Cfengine/Ansible but what is good for you/team/culture?)

Design your SaaS but make sure its ops ready (from the day you start the design)
