 All right, I'm Sean from the Azure Compute Team. We're going to talk about open source at Microsoft. So we're here in Santa Clara across the street is Levi's Stadium. Some of you may know they hosted Super Bowl there a couple of years ago. One of the great things about the Super Bowl is all of the ridiculous things that you can bet on. So you can bet on how long it's going to take to sing the national anthem. You can bet on whether or not somebody will fall off the stage as part of the halftime show. Last year you could even bet on whether one of the Microsoft Surface Taplets that they use on the sideline would break down during the game. Six to one odds, thankfully for us, didn't pay out. But 10 years ago, you would not have even been able to get odds from Vegas on this happening, or this happening, or this happening. I've been at Microsoft for 12 years now, and the transformation that we have made as a company has been nothing short of phenomenal, and it's now the best time ever to be at Microsoft because of the way that we're embracing openness and using open source tools. So in the next couple of minutes, I want to quickly breeze through how we think about OSS at Microsoft and what we're doing. So the most relevant thing for folks here at this particular event is our support for OSS tools and frameworks in Azure. So obviously we have great support for Cloud Foundry that we've been talking about, but we also have a hosted Hadoop Service, HD Insight, a number of the top container orchestrators available as fully open source versions running on Azure and a number of other tools. So if there's an open source tool that you're interested in running on Azure that we don't have there yet, please let us know because we want to make that happen. But you might be saying, okay, well clearly the reason that you're running all of those open source tools is because it's driving Azure consumption. So okay, let's turn it around and look at how we do our own product development and ship products for Microsoft. Anybody familiar with TypeScript? Anybody use TypeScript? So TypeScript is an extension to a superset of JavaScript that transpiles down to standard JavaScript. It's a project that Microsoft has been building in the open for about four or five years now, founded by Anders Helzberg, who is also the founder of Turbo Pascal and C-Sharp. It is now at something like 20,000 commits about 10,000 resolved issues and I believe there's about 200 contributors, active contributors on the project. So pretty active open source project. Visual Studio Code, our lightweight text editor, very similar metrics, thousands and thousands of commits, hundreds of contributors, lots of activity, lots of interest, really great engagement from the community. And last but not least, of course, .NET Core, one of the jewels of our developer suite that we open sourced a couple of years ago, and one where we're seeing really great traction in terms of getting external contributors involved to the point where about half of the commits that we're seeing are coming from externals. Some of the top contributors are coming from external and we're getting additional features from those external contributors. But let's see if we can dig a little deeper. Let's see if there's a team or product at Microsoft that there's no obvious business justification for them adopting open source or adopting open source tools, but that they're really just using it because for the same reasons that a number of you use it, which is because it's the best tool for the job. So let me introduce you to a product known as Microsoft Windows, the Microsoft Windows operating environment. As you can tell from this box, Microsoft Windows is an incredibly old product with a long history in source control and thousands of people that work on it, many of whom have been working on it for, in some cases, decades. I think there are probably half a dozen JavaScript frameworks that have been founded in the last week that are built by people that are younger than Windows. So when Windows decided a couple of years ago that they were going to move all of their source control into Git, it was not initially greeted in the best way. There was a lot of resistance, people were worried about it impacting productivity, adding risk. They had to learn a whole new tool, a whole new way of going about their business. So the engineering systems team who was actually driving the transition of the Windows team into Git, actually put up these posters around buildings in Redmond that walked people through the stages that they were going to go through as they were adopting Git. I actually saw dozens and dozens of people that literally went through all of these stages, all the way up to the final one where they said, huh, this is actually pretty cool. I can switch branches and instantaneously and get great offline support, like, okay, okay, now I'm starting to buy in. The project to migrate Windows to Git ended about a month ago, and I think it's safe to say that it's been successful. As Windows is now the largest Git repo on the planet. Every day there are roughly 4,000 developers making check-ins across more than 400 branches in potentially three and a half million files. The team is still rocking. All of that Git knowledge has led to another pretty cool stat, which is that Microsoft now has more contributors on GitHub than any other company. There's roughly 15,000 employees at Microsoft who have their GitHub identity mapped to their Microsoft ID. So really deep engagement there. So let me wrap up by bringing this back to what we're talking about this week in Cloud Foundry. We've seen in a number of the keynote sessions customers talking about their Cloud Foundry journey, and the way in which it has been about more than technology in the way that they modernize. What they've learned is that modernizing the way that they do business is at least as much about culture and people and collaboration as it is about technology. So Microsoft, and what I'm really excited about us joining the foundation is that we've gone through that process ourselves. We've seen the way that you can change and how you use technology, as well as how you can change your culture. The last thing I'll say is, while it may seem surprising to people that we have so thoroughly embraced open source, if you were paying attention, you may have seen early signs that we're really an open source developer company at heart. I mean, based on stereotypes, doesn't this look like a bunch of open source developers? Heck of a lot of hair and some incredible beards on that photo. Thank you very much.
