Microsoft snaps up GitHub for $7.5 billionJune 4, 2018
Microsoft has reached an agreement to buy GitHub, the source repository and collaboration platform, in a deal worth $7.5 billion. The all-stock deal is expected to close by the end of the year, subject to regulatory approval in the US and EU.
Decade-old GitHub is built on Git, the open source version control software originally written by Linux creator Linus Torvalds. Git is a distributed version control system: each developer has their own repository that they make changes to, and these changes can be propagated between repositories to share those changes. GitHub provides a repository hosting service: a place to put those repositories so that other developers can readily access them. Since its inception, it has become a mainstay of the open source world, with countless projects—including Microsoft projects such as the Visual Studio Code text editor and the .NET runtime—using GitHub repositories as a place to publish their code to the world and coordinate collaborative development. In total, some 28 million developers use GitHub, and there are 85 million code repositories.
On top of its core Git foundation, GitHub has built its own workflows (“pull requests”) to ease the merging of changes from one repository to another. It also has integrated issue tracking, a Web front-end for browsing repositories, and a marketplace for a wide range of commercial add-ons and extensions.
