Over the last decade or so, many technology companies have begun embracing open source. Many use open source tools to run their own IT infrastructure and websites, some offers products and services related to or built on open source tools, and some are contributing to or supporting open source projects.
A 2015 survey from Black Duck found that 78 percent of organizations use open source software, almost twice as many as said the same thing in 2010. In addition, 88 percent said they expect to increase their contributions to open source projects over the next few years, and 66 percent said they consider open source options before they consider proprietary software.
This month we're featuring some of the open source projects that have gotten the most love from tech firms. These are primarily enterprise-focused applications in categories like big data, cloud computing, development tools, systems administration and version control.
As always, if you know of additional tools that you believe should be added to the list, feel free to make a note in the Comments section below.
