Network infrastructure management is an essential part of the technical department of any institution or company, so it must be handled with care and attention to detail. Automating some repetitive processes could bring benefits when it comes to managing them, this can be achieved using Red Hat Ansible.


What is Red Hat Ansible?


Red Hat Ansible is an open-source automation platform that provides tools to automate IT infrastructure, application deployment, and various other tasks. It is designed to simplify and streamline complex tasks in different environments, including cloud, on-premises, and hybrid environments.

Red Hat Ansible Key Features


  • Manuals: Ansible uses simple, readable YAML-based manuals to describe automation tasks. Playbooks allow users to define the desired state of systems and execute tasks sequentially or in parallel on multiple systems.
  • Agentless architecture: Ansible works agentless, meaning it does not require agents to be installed on managed hosts. Instead, Ansible communicates with hosts via SSH (for Linux/Unix) or WinRM (for Windows), making it easy to manage a wide range of systems without installing additional software.
  • Modules: Ansible provides a wide range of built-in modules to perform common automation tasks such as package installation, file manipulation, service management, user management, and more. Additionally, users can create custom modules to extend the functionality of Ansible.
  • Inventory management: Ansible uses inventory files to define the hosts and host groups that it manages. Inventory files can be static or dynamic and can include information such as host names, IP addresses, and host variables.
  • Role-based access control (RBAC): Ansible Tower, the enterprise version of Ansible, offers RBAC capabilities to control user access to automation resources and ensure compliance with organizational policies.
  • Workflow Orchestration and Automation: Ansible allows users to define complex workflows and organize multiple tasks across different systems. This enables automation of entire processes, from infrastructure provisioning to application deployment.
    Integration with cloud providers and IT tools: Ansible integrates with various cloud providers (such as AWS, Azure, and Google Cloud Platform) and IT tools (such as monitoring systems, version control systems, and ticketing systems) to automate tasks across IT.
  • Community and ecosystem: Ansible has a large and active community of users and contributors who share guides, modules, and best practices. Additionally, Red Hat offers support and professional services for Ansible through its Ansible Automation Platform.

How to use Red Hat Ansible for network management


Red Hat Ansible is widely used for network management and automation and offers several benefits in this domain:


  • Configuration Management: Ansible allows network administrators to define the desired state of network devices using simple and readable YAML-based manuals. This enables consistent configuration management across devices and reduces the risk of configuration drift.
  • Automated provisioning: Ansible can automate the provisioning of network devices, including routers, switches, firewalls, and load balancers. This streamlines the process of deploying new devices or updating existing ones, saving time and reducing manual errors.
  • Inventory Management: Ansible provides flexible inventory management capabilities, allowing network administrators to define hosts and host groups in inventory files. This makes it easier to organize and manage large networks and perform specific automation tasks.
  • Task automation: Ansible's modular architecture and extensive library of networking modules enable the automation of common networking tasks, such as device provisioning, firmware updates, VLAN configuration, port management, and security policy enforcement.
  • Integration with network devices: Ansible can communicate with network devices using various protocols, including SSH, Telnet, and API. This allows you to manage a wide range of network equipment from different vendors, providing a unified automation platform for heterogeneous environments.
  • Validation and testing: Ansible playbooks may include validation tasks to ensure that network configurations comply with organizational policies, industry best practices, and regulatory requirements. Additionally, Ansible can be used to perform automated testing of network changes before they are applied to production environments.
  • Scalability and performance: Ansible is designed to scale across large networks and handle thousands of devices simultaneously. It uses a lightweight agentless architecture, allowing it to execute tasks quickly and efficiently without consuming excessive network resources.


Overall, Red Hat Ansible is a powerful tool for network automation, offering network administrators a flexible and scalable platform to automate routine tasks, improve operational efficiency, and improve network reliability and security.
