Migrating from VMware to OpenStack

 

Broadcom's acquisition of VMware has raised concerns among VMware users about price increases and changes in service levels. Historically, after Broadcom's acquisitions, like those of CA Technologies and Symantec, customers experienced significant cost increases and decreased quality of support and development.

We help you move from your VMware environment. We have successfully completed several migration projects to OpenStack, including our own VMware environment.

Migrate with minimal customer impact and downtime

Using our expertise in both OpenStack and VMware, we have developed a tool that fully automates the move to minimise customer impact and downtime.

During service windows, we can schedule the move of VMs and also carry out individual acceptance testing per VM to guarantee the quality of the moves. Managing 100 VMs (depending on size) in a single service window is thus manageable.

The automated migration is divided into three phases to ensure a smooth transition with minimal impact on the business.

Want to know more? Contact us and we'll explain the process in more detail.

 

1. Preparation

The system evaluates the instance and identifies the services that are critical to your business.

We retrieve metadata from VMware to e.g. reuse MAC addresses and minimise the impact on migration. Relevant ports and VLANs are created in OpenStack to prepare for a seamless transition.

If monitoring is used, a migration window is set via the API to avoid false alarms and unnecessary downtime.

2. Migration

During a scheduled migration window, the instance is taken down and its disc image is copied to OpenStack.

Next, the disks are mounted and updates are made to ensure compatibility, such as installing KVM drivers and updating the network configuration.

The new instance is then created in OpenStack with the correct metadata, ports and configurations to mirror the original environment.

3. Functional check

After the migration, the instance is started in OpenStack and we perform an acceptance test to ensure that the instance responds to the ports or services identified in step one.

If the instance does not pass the acceptance test, the ports in OpenStack are closed and the instance is restarted in VMware. The instance remains in OpenStack, making it possible to troubleshoot the problem afterwards without risking unnecessary downtime of your operating environment.

If the instance passes the acceptance test, the CMDB is automatically updated to confirm the migration, and the instance is marked as migrated in VMware. The tool now moves on to the next instance.

Now the instance is running from OpenStack!

Several successful migrations, including our own VMware move

We have successfully moved our own VMware environment to OpenStack. The migration went smoothly and without problems, which makes us feel confident in delivering the same project to our customers. We have moved environments with over 500 virtual machines (VMs) and ensured a safe and stable transition to OpenStack.

We have the tool, we have done the moves, we have the know-how

Thanks to our experience and knowledge, in both OpenStack and VMware, we can offer efficient and scalable migration solutions that help you quickly benefit from OpenStack's cost efficiency, flexibility and scalability.

Read our success case here

Moving from VMware to OpenStack can offer several benefits, especially for organisations seeking flexibility, cost efficiency and scalability. Here are three main benefits of such a transition:

Cost-effectiveness: OpenStack is known for its ability to reduce total cost of ownership (TCO). Because it is an open source platform, it eliminates licensing fees typically associated with proprietary solutions like VMware.

Flexibility and open source: OpenStack is highly customisable thanks to its open source model. This flexibility facilitates integration with a wide range of third-party technologies and tools, which is a great advantage for organisations that value technological freedom and innovation.

Scalability: OpenStack is designed to scale horizontally across many servers, making it well suited for large, distributed environments. This is an important factor for organisations that need to manage large amounts of data and users across geographically dispersed locations. The platform's modular design also makes it possible to efficiently add or modify services without disrupting the overall infrastructure

Of course compatible with your container platform

In OpenStack, of course, OpenShift/OKD can run. OpenShift uses OpenStack's API to provision resources in the platform, but unlike in VMware, you can also do it yourself, either through a web portal, API or via CLI.
