Running open source virtual machines… on Microsoft Windows Azure? Welcome to the VM Depot

Last week I gave a talk on open source as part of a Microsoft Azure for Education day at UCL in London. I was sharing the stage with Stephen Lamb from Microsoft, who gave a great overview of the various open source projects that Microsoft are engaged in, including Node.js and PHP for Windows. But the main highlight was VM Depot.

VM Depot is a way to upload, share, and deploy virtual machine images on Microsoft’s Windows Azure cloud platform. For example, you can easily find common open source packages such as Drupal and WordPress on various Linux operating systems available as VMs, so that you can create and run your own instances.

This makes it very easy to get started with open source packages, as all the dependencies and related components and configuration are all set up and ready to use – for many packages this means just doing your customisation for things like your own web domain and personalising the user interface.

As well as the usual suspects such as Drupal, the VM Depot can host all kinds of other software; for example, you can deploy the Open Data portal platform CKAN. This opens up possibilities for using the service for more niche requirements, for example you could create a VM image of your research software and dataset to make it easier for reviewers to run your experiments. Or you can modify an existing image to include extensions and enhancements that may target a more specialist audience, for example you could create a WordPress image with templates and add-ons to run as an overlay journal rather than a regular blog.

So why is Microsoft doing this?

Well, it seems to fit as part of the drive towards Microsoft being less of a software company and more of a device manufacturer and cloud services provider. When it comes to offering  cloud services, its less important what your customers choose to run on them, so much as making sure they can run whatever they need. For most organisations that usually means a mixture of closed source and open source packages; by offering the VM Depot, Microsoft can serve these customers as part of an existing relationship, rather than force them to go with other service providers for running open source products.

Microsoft have certainly come a long way since the infamous “cancer” remark.
