Ansibles Callback plugins control most of the output you see when running the command line programs, but can also be used to add additional output, integrate with other tools and marshall the events to a storage backend
Ansible is a great tool for automating IT workflows, and I use it to manage hundreds of servers and cloud services on a daily basis. One of my small annoyances with Ansible, though, is it's default CLI output—whenever there's a command that fails, or a command or task that succeeds and dumps a bunch of output to the CLI, the default visible output is not very human-friendly.

You can migrate any existing standalone role into a collection and host the collection on Galaxy. With Ansible collections, you can distribute many roles in a single cohesive unit of re-usable automation. Inside a collection, you can share custom plugins across all roles in the collection instead of duplicating them in each role’s library/` directory.
You must migrate roles to collections if you want to distribute them as certified Ansible content.
Sometimes you want a task to run only when a change is made on a machine. For example, you may want to restart a service if a task updates the configuration of that service, but not if the configuration is unchanged. Ansible uses handlers to address this use case. Handlers are tasks that only run when notified. Each handler should have a globally unique name.
This topic describes how to create Ansible roles that can be imported into Galaxy.
Collections are a distribution format for Ansible content. You can use collections to package and distribute playbooks, roles, modules, and plugins. You can publish and use collections through Ansible Galaxy.
Ansible is an open-source IT automation software that automates the IT infrastructure. It creates an automated and consistent IT environment which makes IT task much easier and faster. Such an environment is self-regulating that can manage all the IT services without using any additional agent. It set up an automated environment for server, OS, Application and other IT services and configures them for better access. It also manages the deployment of any application on the system. Ansible uses to configure a variety of IT materials such as network devices, servers, database storage, cloud infrastructure, firewall, and any other virtual/physical platform. It automates the administrator’s task and allows fast access to various IT services. Ansible uses YAML language that describes system configuration to manage the IT services.
