    Overview of Red Hat Ansible | RHCE | EX294

    Ansible is an essential tool for Red Hat Certified Engineers(RHCE) which offers open-source automation to simplify complex IT processes and tasks. It helps to reduce repetition, streamline workflows, and ensure systems run efficiently.

    Here are some common use cases for Ansible:

    • Eliminate repetition and simplify workflows
    • Manage and maintain system configuration
    • Continuously deploy complex software
    • Perform zero-downtime rolling updates

    Ansible operates through human-readable scripts known as playbooks where you define the desired state of local or remote systems. Ansible then ensures these systems consistently maintain that state, enhancing reliability.

    Objective

    Key Features of Ansible | RHCE | EX294

    As automation technology, Ansible is designed around the following principles:

    • Agent-less architecture

      Minimizes maintenance by avoiding the need to install software agents on your infrastructure.

    • Simplicity

      Ansible playbooks are written in YAML which is a clear and human-readable format. This simplicity ensures that the automation code reads like documentation, making it easier to manage. Ansible also connects to remote machines using SSH and existing OS credentials, further simplifying setup.

    • Scalability and flexibility

      Ansible easily scales across a variety of systems through a modular design. Whether you’re automating operating systems, cloud platforms, or network devices its flexibility allows for rapid expansion and adaptability.

    • Idempotence and predictability

      Ansible excels at maintaining idempotence, meaning that once a system reaches the state described in the playbook, no additional changes are made, even with repeated playbook runs. This ensures predictable and consistent outcomes every time automation is executed.
