That could be quite a windfall for Microsoft, which now owns top sites for job searching and developer collaboration. With the combination of recent acquisitions LinkedIn and now GitHub, Microsoft owns two of the most influential professional networks.
"Every business is a software business," Nadella told CNBC's "Squawk Alley," citing LinkedIn hiring data in fields like retail and energy. "Developers are going to be required everywhere."
The obvious benefits from Microsoft's acquisition of GitHub are the ways it can augment Microsoft's cloud product, Azure.
But less obvious is that GitHub, where coders and programmers discuss and learn computer science techniques, can also serve as a portfolio of professional products — a feature Andreessen Horowitz recognized when it invested in 2012.
The theory has held up:
The fact that Microsoft owns two of the top recruiting tools for tech jobs matters because firms will pay top dollar to hire the best coders. Companies are even hiring chefs from Michelin-starred restaurants for their company food services to recruit and retain talent.
There's no sign that Silicon Valley's war for top talent will subside soon — and while neither GitHub nor LinkedIn focus on education, both offer tools to help professionals stay competitive.
Indeed, Udacity, an online education website, lists GitHub and LinkedIn profiles as two top ways to impress future employers.
"LinkedIn profiles are an extremely valuable asset to your job portfolio. Unlike a resume, which is confined by length, you are able to describe in more detail the projects or work that you have done on your LinkedIn profile," Udacity said. "GitHub, in addition to being an essential tool and resource for programmers, is a powerful networking tool. Hiring managers will look at your profile when considering you for a role."
