ansible alternatives

The alternative scheme of virtual function includes NVI technique and strategy design mode. The NVI technique itself is a special form of template method design mode.One drawback of moving functions from member functions to class external functions is that non-member functions cannot access the Non-public members of class.The Tr1::function object behaves like a generic function pointer. Such an object can accept all the callable objects (callable entities) that are compatible with the given targ

It is written in Python and is similar to Chef and Puppet. but there is a difference and advantage that we do not need to install any client in the node. It uses SSH to communicate with nodes. In this article, we will install and configure Ansible on CentOS7 and try to manage the two nodes.
