An example of OpenStack UsageThe second largest car manufacturer in the world, Volkswagen Group, will use the open-source cloud computing platform OpenStack to build a private cloud that will host websites for its brands VW, Audi and Porsche, and will be a platform for innovating automotive technology, the company announced Wednesday. For the past two years, VW officials at the company’s Wolfsburg, Germany, headquarters debated what platform to use. VW decided to first build out a private cloud based on OpenStack that will eventually span thousands of physical nodes across multiple data centers in the U.S., Europe and Asia. Eventually VW hopes to incorporate public cloud resources to create a hybrid cloud, said officials with VW’s consultant, Mirantis.
When fully built out, VW’s private cloud could be one of the top five or 10 largest OpenStack-based clouds in production, said Mirantis co-founder and chief marketing officer Boris Renski. According to the OpenStack Foundation’s user survey in October 2015, only 7% of OpenStack production deployments surpassed 1,000 nodes. Only 2% of OpenStack deployments were in the industrial/manufacturing industry.
“The Group IT Cloud is a new way to deliver Volkswagen applications at any scale, in a single global network, consistent across VW brands,” wrote Mario Mueller, Corporate Director IT Operational Services & Infrastructure Technologies, Volkswagen Group in an email interview. “Over time, all net new applications will run on this cloud which will naturally replace most of the legacy systems.” It will not replace legacy systems, but instead will host most of the company’s newly developed applications.

What is All About OpenStack
It’s built entirely atop x86 hardware, using a Red Hat operating system and the Kernel Virtual Machine (KVM) hypervisor (95% of OpenStack production clouds use KVM, OpenStack’s user survey shows) with Mirantis’ licensed OpenStack distribution provisioning the virtual machines.

 VW officials said they’re using OpenStack’s Nuetron/OVS/VXLan technology for networking and Ceph for storage, with others likely to be added. Renski said VW is in the final stages of choosing a platform as a service (PaaS) layer to act as an application development and hosting environment that would run on top of the OpenStack IaaS.
