Agile DevOps - People and Process then Automation!!!

Use Cloud and DevOps to build infrastructure by rapid agile iterative development using collaborative open source tools:
-Terraform or Cloud Formation for easy orchestration.
-chef cookbooks, puppet modules or ansible playbooks to build servers.
-Test Kitchen to deploy and test them.
-Packer for build server images or containers.
-EC2Dream a graphic user interface that provides a 'single pane of glass' to do agile devops primarily on cloud servers.
-Amazon AWS, Azure, Google Compute Engine, IBM, Openstack, Local and Hosted servers.

Library Management Chef Puppet Ansible

Operating Systems have package managers (well linux does -)) so software can be install from a remote location i.e.
    yum install apache.
Languages have packaging formats (e.g. Java - jar files, Ruby gems) and some have package managers (e.g. Ruby - gem command) or ways to use the package in builds (e.g. Java - Maven).

So it is not suprising that ways to reuse and remotely install ansible roles, chef cookbooks and Puppet modules have developed. The tools automatically find ansible roles on Ansible Galaxy, chef cookbooks on the Chef community site and puppet modules on the Puppet Forge site as well as source management systems like github. All allow anyone to signup and contribute.

    Librarian Ansible is the most common tool used for Ansible.
    Librarian Puppet is the most common tool used for Puppet.
    Berkshelf is the most common tool for chef.

So the development of cookbooks/modules is now separated into:
    library cookbooks/modules/roles that are specified to Berkshelf or Librarian Puppet/Ansible.
    application cookbooks/modules/roles that are written in the repository and call the library cookbooks.
typically application cookbooks/modules/roles have a prefix like
to create a unique name and to identify them as application cookbooks/modules/roles.

Test Kitchen supports this methodology
