Chapter 2. Red Hat Ansible Automation Platform Architecture
As a modular platform, Ansible Automation Platform provides the flexibility to easily integrate components and customize your deployment to best meet your automation requirements. The following section provides a comprehensive architectural example of an Ansible Automation Platform deployment.
2.1. Example Ansible Automation Platform architecture
The Red Hat Ansible Automation Platform 2.4 reference architecture provides an example setup of a standard deployment of Ansible Automation Platform using automation mesh on Red Hat Enterprise Linux. The deployment shown takes advantage of the following components to provide a simple, secure and flexible method of handling your automation workloads, a central location for content collections, and automated resolution of IT requests.
- Automation controller
- Provides the control plane for automation through its UI, Restful API, RBAC workflows and CI/CD integrations.
- Automation mesh
- Is an overlay network that provides the ability to ease the distribution of work across a large and dispersed collection of workers through nodes that establish peer-to-peer connections with each other using existing networks.
- Private automation hub
- Provides automation developers the ability to collaborate and publish their own automation content and streamline delivery of Ansible code within their organization.
- Event-Driven Ansible
- Provides the event-handling capability needed to automate time-consuming tasks and respond to changing conditions in any IT domain.
The architecture for this example consists of the following:
- A two node automation controller cluster
- An optional hop node to connect automation controller to execution nodes
- A two node automation hub cluster
- A single node Event-Driven Ansible controller cluster
- A single PostgreSQL database connected to the automation controller, automation hub, and Event-Driven Ansible controller clusters
- Two execution nodes per automation controller cluster
