Chapter 2. RPM topologies
The RPM installer deploys Ansible Automation Platform on Red Hat Enterprise Linux by using RPMs to install the platform on host machines. Customers manage the product and infrastructure lifecycle.
2.1. RPM growth topology
The growth topology is intended for organizations that are getting started with Ansible Automation Platform and do not require redundancy or higher compute for large volumes of automation. This topology allows for smaller footprint deployments.
2.1.1. Infrastructure topology
The following diagram outlines the infrastructure topology that Red Hat has tested with this deployment model that customers can use when self-managing Ansible Automation Platform:
Figure 2.1. Infrastructure topology diagram
Each virtual machine (VM) has been tested with the following component requirements: 16 GB RAM, 4 CPUs, 60 GB local disk, and 3000 IOPS.
| VM count | Purpose | Example VM group names |
|---|---|---|
| 1 | Platform gateway with colocated Redis |
|
| 1 | Automation controller |
|
| 1 | Private automation hub |
|
| 1 | Event-Driven Ansible |
|
| 1 | Automation mesh execution node |
|
| 1 | Database |

2.1.2. Tested system configurations
Red Hat has tested the following configurations to install and run Red Hat Ansible Automation Platform:
| Type | Description |
