Ansible is an open-source automation tool, or platform, used for IT tasks such as configuration management, application deployment, infraservice orchestration, and life cycle automation. Automation is crucial these days, with IT environments that are too complex and often need to manage scalability in order to balance load management, otherwise it will be difficult for system administrators to manually configure each machine of the server rack. It is agentless which means we can access all nodes or servers from a single node known as the master node without installing it on the other nodes. It is developed by using the Python programming language. Automation simplifies complex tasks, not just making developers' jobs more manageable but allowing them to focus attention on other tasks that add value to an organization. In other words, it increases efficiency and time. It also gives you the power of deploying multi-tier applications. Ansible, as noted above, is rapidly rising to the top in the world of automation tools
Ansible communicates with remote machines over the SSH protocol. By default, it uses native OpenSSH and connects to remote machines using the current user name, just as SSH does. It works by associating with the machines on the network and pushing out Ansible modules to them. These projects are composed to be asset models of the ideal condition of the framework. Ansible then, at that point, executes these modules (over SSH naturally), and eliminates them when wrapped up. The library of modules can live on any machine, and there are no servers, daemons, or databases required. Typically, the work will be done on any terminal program, a text editor, or probably a version control system to keep track of changes on the content. Passwords are supported, but SSH keys with ssh-agent are one of the best ways to use Ansible.
Protocols And Uses
The Protocols most used in Ansible is the SSH protocol. It can be extended to support other transport protocols such as SNMP or message bus by dropping a custom plugin into the connection_plugins directory. Connection plugins can be set globally in the ansible configuration.
