Another key difference between Ansible and the other tools that it is commonly compared to is that the majority of these tools have their origins as systems that are designed to deploy and police a configuration state.

They typically require an agent to be installed on each host, that agent discovers some information about the host it is installed on, and then calls back to a central server basically saying Hi, I am server XYZ, could I please have my configuration? The server then decides what the configuration for the server looks like and sends it across to the agent, which then applies it. Typically, this exchange takes place every 15 to 30 minutes—this is great if you need to enforce a configuration on a server.

However, the way that Ansible has been designed to run allows it to act as an orchestration tool; for example, you can run it to launch a server in your VMware environment, and once the server has been launched, it can then connect to your newly launched machine and install a LAMP stack. Then, it never has to connect to that host again, meaning that all we are left with is the server, the LAMP stack, and nothing else, other than maybe a few comments in files to say that Ansible added some lines of configuration—but that should be the only sign that Ansible was used to configure the host.
