"Public clouds today feature a very broad range of infrastructure services and go horizontally across all industries," Mueller explains. "Because of that, when it comes to large-scale vertical use cases - like automotive cloud for VW group - the economics don't work as well."
However, he adds that VW is not going for an exclusively private cloud, and will be looking into hybrid cloud in the near term.
But over time all net new applications will run on this cloud, which will also replace most of the legacy systems.
There are three main phases to the project. The first was to have the initial version of the infrastructure as a service (IaaS) cloud complete by December 2015, while phases two and three are penned in for completion by July this year.
These will include enhancements to IaaS and a hybrid version of IaaS, along with the company's first platform as a service implementation with a CI/CD toolchain. Customer-facing applications will begin to appear around July 2016, the company hopes.
Volkswagen expects to scale the project across multiple data centres in America, Europe and Asia, with thousands of physical hosts. Its first OpenStack cloud, located in Wolfsburg, Germany, comprises a few hundred physical nodes.
Of course, there are challenges ahead for businesses embracing OpenStack.
For its part, Volkswagen would like to see features in OpenStack to make replacing legacy virtualisation systems easier, and to make it usable as one platform across all workloads.
"Although we're not prepared to disclose specifics yet," Mueller says, "VW will closely collaborate with the OpenStack community, as well as Mirantis and Intel, to make these enhancements."
