ARM-based Cloud: Deployment Blueprint on

Overview

Mon, 01 Jan 0001 00:00:00 +0000

Ampere is a semiconductor design company that develops server-grade processors for cloud environments, with a focus on high performance and energy efficiency.

You can deploy and verify an OpenNebula cloud on Ampere hardware, by using Certified Ampere Hardware with OpenNebula software, a set of Ansible playbooks that allows you to deploy and verify an OpenNebula cloud with a few simple commands.

This guide provides a reference Ampere hardware specification that has been used to verify OpenNebula. It includes instructions on how to perform a ZeroTouch deployment of OpenNebula on the certified hardware, and provides a reference architecture and configuration.

Hardware Specification and Architecture

Mon, 01 Jan 0001 00:00:00 +0000

This section contains the specification of the used Ampere hardware and software resources for the reference OpenNebula deployment.

Architecture

The target high-level cloud architecture overview is shown below. Two Ampere servers are used: the first for hosting the OpenNebula Front-end services and VMs, the second for hosting VMs only. A simple VXLAN networking is configured for the communication between the VMs, so all deployed VMs are attached to the same logical LAN.

Automated Deployment and Configuration

To perform the automated deployment of an OpenNebula cloud, the Ampere infrastructure of connected servers must be previously configured and available. This guide provides guidance on how to extract the list of required parameters of the provisioned infrastructure – which will later be used for the automation of the OpenNebula deployment – and an outline of the process for the automated deployment of an OpenNebula cloud.

Ampere Infrastructure Provisioning

Provisioning the Ampere infrastructure on premises is out of the scope of this guide. To perform the automated deployment of an OpenNebula cloud, the Ampere infrastructure must meet the following conditions:

Tip

This guide provides the basic steps. If you wish to see a more detailed guide, please refer to Deploying a Virtual Machine Locally.

After successfully verifying the infrastructure deployed by the automations, to run a Virtual Machine access the OpenNebula web UI at:

http://<Front-end IP>:2616/fireedge/sunstone

To log in, use the default username oneadmin, and the password specified in the one_pass variable of the inventory file.
