Ansible is a python package, is a complete unpack and play software, the only requirement for clients is that SSH has python, and python-simplejson packages, deployment simple to heinous. The following article will give you the main introduction of Ansible as a Python module library use of the method example, the need for friends can reference.

The main criticism of the Java Community for C # Is that it claims that C # is just a lame Java clone version-rather than a result of language innovation, it is a result of litigation. In the C ++ community, the main criticism (also targeting Java) is, C # Is just anothe
