Automate Your Network With Ansible

Automate Your Network With Ansible

Traditional, manual approaches to network configuration and updates are too slow and error-prone to effectively support the needs of today’s rapidly shifting application and data transfer requirements. Programmable, software-based automation technologies can help your team better support your organization’s digital initiatives.

With network automation, network operations (NetOps) teams can quickly respond to dynamic, ever-changing workload requirements for flexible capacity, application security, load balancing, and multicloud integrations. They can also implement self-service and on-demand network activities.

As a result, NetOps teams can become as agile and flexible as applications and infrastructure teams to support modern business demands.

When Should You Use Red Hat Ansible Tower

We recommend you use Red Hat Ansible Tower when you need:

  • Centralized control for multiple people to use the same playbooks.
  • Application programming interface (API) control of playbooks.
  • Integration with remote authentication tools.
  • Compliance checking and enhanced logging.
  • More than just network automation.

Understanding Playbooks

Playbooks are Ansible’s configuration, deployment, and orchestration language. They consist of sets of human-readable instructions called plays that define automation across an inventory of hosts. Each play includes one or more tasks that target one, many, or all hosts in the inventory. Each task calls an Ansible module that performs a specific function like collecting useful information, backing up network files, managing network configurations, or validating connectivity

Playbooks can be shared and reused by multiple teams to create repeatable automation.

Understanding Inventories

An inventory is a collection of hosts that may be acted on using Ansible commands and playbooks. Inventory files organize hosts into groups and can serve as a source of trust for your network. Using an inventory file, a single playbook can maintain hundreds of network devices with a single command. This chapter explains how to build an inventory file.

Galaxy Roles

A role bundles Ansible automation content to make it reusable. Instead of creating long playbooks with hundreds of tasks, you can use roles to organize and break tasks apart into smaller, more discrete units of work. A role includes all of the tasks, variables and handlers needed to complete the unit of work.
