Migrate from VMware to OpenStack

 

Broadcom's acquisition of VMware has raised concerns among VMware users about price increases and changes in service levels. Historically, following Broadcom's acquisitions, such as those of CA Technologies and Symantec, customers experienced significant cost increases and reduced quality in 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.

Numerous successful migrations, including our own VMware move

We have successfully moved our own VMware environment to OpenStack. The migration went smoothly and seamlessly, which makes us confident in delivering the same projects to our customers. We have moved environments with over 500 virtual machines (VM) and ensured a secure and stable transition to OpenStack.

We have - the tool - carried out moves - 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-effectiveness, flexibility and scalability.

Migrate with minimal customer impact and downtime

With the help of our expertise in both OpenStack and VMware, we have developed a tool that fully automates the migration to minimize customer impact and downtime.

During maintenance windows, we can schedule the migration of VMs and also perform individual acceptance testing per VM to guarantee the quality of the migrations. Managing 100 VMs (depending on size) within a single maintenance window is thus feasible.

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

Preparation

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

We retrieve metadata from VMware to, for example, reuse MAC addresses and minimise migration impact. Relevant ports and VLANs are created in OpenStack to prepare for a smooth transition.

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

Move

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

The disks are then 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.

Function check

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

If the instance fails the acceptance test, the ports in OpenStack are closed and the instance is restarted in VMware. The instance remains in OpenStack, allowing troubleshooting of the problem afterwards without risking unnecessary downtime in your operational 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 then proceeds to the next instance.

The instance is now running from OpenStack!

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

Cost-efficiency: OpenStack is known for its ability to reduce total cost of ownership (TCO). Since it is an open source platform, license fees typically associated with proprietary solutions like VMware are eliminated.

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 major advantage for organisations that value technical 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 enables services to be added or modified efficiently without disrupting the overall infrastructure.

Of course compatible with your container platform

In OpenStack, OpenShift/OKD can of course be 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.
