A Nutanix OpenStack deployment is made up of 3 components:
- OpenStack Controller (OSC)[list]
- This can be an existing or new deployment that hosts the OpenStack UI, API, and services. This handles all of the OpenStack API calls and is your main point of management for OpenStack
- These translate OpenStack RPCs from the OSC into Acropolis API calls transparently. These allow you to utilize existing OpenStack automation or create new ones using the standard OpenStack API. The drivers can be deployed in 2 modes
- Integrated on the OSC. The drivers can be installed directly on the OSC removing the need for additional VMs and following the OSC’s scaling/load balancing
- Standalone package. The drivers are also available in a standalone VM
- Available from portal.nutanix.com, this is an all-in-one VM that provides the drivers and easy integration to the OSC with a few simple commands. The OVM is stateless, which means it can easily be scaled out by simply deploying more and putting them behind a load balancer
- The OVM is also available in an all-in-one mode for test/dev and lab environments that provides both the drivers and OSC in a single package. The OSC in this mode is very simple to deploy. However, it’s important to note that in all-in-one mode the drivers are supported by Nutanix but the OpenStack deployment is not.
Where does Nutanix fit in with my OpenStack environment?
An OpenStack deployment is made of many layers, depending on the features and services you require. At its core, however, is the infrastructure. Cinder, Neutron, and Nova provide the resource management needed for storage, networking, and compute respectively. Glance provides images for your users to deploy VMs from.
As you can see here, Nutanix sits at the core, providing the IaaS base for OpenStack. This gives your OpenStack deployment many benefits:

Turnkey - Nutanix provides simple to use building blocks for private clouds. You can easily scale compute and storage linearly removing bottlenecks common with 3-tier architecture. One-click operations for cluster expansion and rapid procurement means that you have what you need when you need it, saving on expensive overprovisioning.
Simple – Nutanix Prism offers integrated break-fix procedures for all the hardware and proactive monitoring for things that might cause problems down the road. Prism now also offers predicative capacity planning, allowing you to easily see based on your growth rates how long your infrastructure will last, including ways to squeeze the most out of it by identifying stale and overprovisioned VMs.
Resilient – Nutanix Acropolis offers automated self-healing and a rich set of options to keep your critical data safe, including integrated data protection and VM-centric features such as VM Snapshots, live migrations, and high availability. In a study by IDC, Nutanix environments had 98% lower unexpected downtime compared to traditional systems.
Integrated – With Nutanix Acropolis providing built-in storage and virtualization with AHV, the entire infrastructure is delivered from a single vendor, radically simplifying integration and giving you single-number support for all your infrastructure needs. As an integrated stack, Prism offers one-click non-disruptive software management for everything in the infrastructure (BIOS/BMC/Storage/Hypervisor) meaning there’s no need for expensive professional services to upgrade your system or long planning periods to avoid issues.
And that’s just the beginning! There are many benefits to backing your OpenStack deployment with Nutanix infrastructure.
