Red Hat flips its lid for open-source computing tools. The company dominates the market for Linux, the open-source computer operating system (OS) for enterprise computing infrastructure and applications. In addition to its Red Hat Enterprise Linux OS, the company's product line includes database, content, and collaboration management applications; server and embedded operating systems; and software development tools. Red Hat also provides consulting, custom application development, support, and training services. The company's business model is a mix of providing free, open-source software paired with subscription-based support, training, and integration services. In 2019, Red Hat was acquired by IBM for about $34 billion.
