GitHub is now a Microsoft Development platform. Previously, it has been a development promoting platform for a long time and developers rely on this open source service for their development oriented tasks. Earlier this year, Microsoft announced that it will be acquiring GitHub for 7.5 billion USD. Quite recently, Microsoft revealed that it has made the whole process of acquisition complete.
Microsoft explains that it is its vision to support and help developers and acquiring GitHub is a part of implementing this vision. GitHub will continue to run as an independent business. Not only this is a large repository, it is a popular resource for developers and organizations for documenting and hosting code. The core idea of GitHub is not turning into Microsoft, but more of getting insights to the current developer trends going around outside of traditional Microsoft technologies. Not only it will help the company grow with these insights so as to make developers facilitate from their technologies, it will also help Microsoft towards providing a better Microsoft Development platform in future.
