VMware Migration to OpenStack
Broadcom’s acquisition of VMware and subsequent licensing changes have incentivized organizations around the world to re-evaluate their virtualization strategy. OpenStack, the open source standard for cloud infrastructure, has emerged as a leading alternative. Over 80% of OpenInfra members have already talked to customers about migrating workloads from VMware to OpenStack.
OpenStack’s flexibility and open development enables organizations to:
- Implement a cost effective virtualization strategy by avoiding vendor lock-in
- Modernize their infrastructure with a cloud native strategy
- Customize their stack through increased integration options
- Rely on a global ecosystem and diverse, active open source contributors
- Maintain complete ownership of their infrastructure
Planning a migration from VMware?
This migration guide outlines the why, when, and how, with technical insights and examples from global adopters.

OpenStack Features that aren’t in VMware
OpenStack | VMware |
---|---|
SSH key or user data injection OpenStack provides out-of-the-box SSH key and user data injection via the metadata API endpoint with the help of cloud-init. The user can configure this dynamically. | SSH key or user data injection This capability doesn’t exist out of the box in VMware. It is technically possible to inject keys or user data via a template and cloud-init or script into the VM. |
Concept of ephemeral data and base images In OpenStack the recommendation is to use virtual machine images that rely on base images as ephemeral. This follows the cloud-native approach and enables CoW (Copy on Write), which provides significant benefits in boot speed and resource savings (i.e., no data copy). | Persistent disks only By definition, all disks in VMware are persistent. |
Adjusting based on your needs OpenStack and its components are open source and can be adjusted if necessary. For example, new capabilities can be added, or third-party tools can be integrated. | Adjusting based on your needs VMware is closed source and cannot be modified. All missing requirements need to be implemented by Broadcom. |
