===== Statements =====
  *"[[http://en.wikipedia.org/wiki/Apache_Maven|Maven]] + [[http://en.wikipedia.org/wiki/Jenkins_%28software%29|Jenkins]] + a good script shell and/or script language ( Bash, Windows PowerShell, Tcl/Tk, Python..) as collection are good enought to practice DevOps, successfully  :-).

==== Configuration Management Software ( CM Software / CMS ) ====
=== The most simple Solution: Bash Scripts for Linux, PowerShell Scripts for Windows ===
  *Just execute Bash scripts on Linux, or PowerShell scripts for Windows to configure your servers.
=== Ansible ===
  *The OpenSource [[http://www.ansible.com/|Ansible]], written in Python.
    *[[http://galaxy.ansible.com/|Ansible Galaxy]] - "Find, reuse, and share the best Ansible content".
    *The online service [[http://www.ansible.com/tower|Ansible Tower]] - "Manage up to 10 servers/instances for free!". 
    *[[http://docs.ansible.com/|Ansible Documentation]].
      *[[http://docs.ansible.com/developing_api.html|Ansible Documentation "Python API"]].
    *[[http://www.github.com/ansible|GitHub "ansible"]] - "A radically simple IT automation platform that makes your applications and systems easier to deploy. Avoid writing scripts or custom code to deploy and update your applications— automate in a language that approaches plain English, using SSH, with no agents to install on remote systems".
    *[[http://pypi.python.org/pypi/ansible/|The Python Package Index "ansible"]].
  *Ansible uses YAML for communications. So the communications is declarative. So you have to write YAML data. 
  *Ansible doesn't require a client on the target systems.
  *I was told by experts in 2015 "Ansible and Docker are a strong combination", supposing that the reputation, importance and success of Ansible will rise with the expected glorious success of Docker.

  *IBM uses "Chef" for the installation of the IT configuration management software "IBM The Cloud Manager with Openstack" ( CMwO ).
    *[[http://www.ibm.com/support/knowledgecenter/SST55W_4.1.0/|IBM Knowledge Center "IBM Cloud Manager with OpenStack welcome page"]] - "IBM Cloud Manager with OpenStack V4.1.0 documentation".
  *Chef uses the Ruby language for communications.  So the communications is imperative. So you have to write Ruby code.
  *Chef requires a Chef client on the target systems.
  *Chef parses its documents 2 times ( it reads the Chef source files 2 times ):
    -Parsing of the Ruby script.
    -Execution of special "blocks".
  *Chef offers BDD / TDD alike test options!
  *[[http://en.wikipedia.org/wiki/Chef_%28software%29|EN.Wikipedia "Chef (software)"]].

It provides a basic suite of operations for executing local or remote shell commands (normally or via sudo) and uploading/downloading files, as well as auxiliary functionality such as prompting the running user for input, or aborting execution."

    *[[http://en.wikipedia.org/wiki/Salt_%28software%29|EN.Wikipedia "Salt (software)"]].
    *SALT may be used with Vagrant ( see [[virtualization.html|Virtual PCs, Virtual Servers, Virtualization, Virtual Computers, Computer Hardware Simulation]] ) for provisioning a "project" filespace on a virtual project computer and the transportation of data. In opposite, SALT is used for preparation of the development system ( IDE, compilerchain,... ) on the host development workstation, not on the virtual project computer.
    *Both SALT and later the IDE on the host development workstation have access to a mapped filesytem on the virtual project computer.
=== Serverspec - RSpec Tests for Server Configurations ===
  *See [[specbyex.html|Specification by Example]].
=== Resources ===
  *Though most configuration management software is originally developed for Linux and its typical silent installation procedures, Windows editions of such tools might easily use "Microsoft PowerShell" on Windows to execute and control Windows non-GUI installers.
