Red Hat, Inc. is a provider of open source software solutions, using a community-powered approach to develop and offer operating system, virtualization, middleware, storage and cloud technologies. The Company employs an open source development model. The open source development model allows it to use the collective input, resources and knowledge of a global community of contributors who can collaborate to develop, maintain and enhance software because the human-readable source code for that software is publicly available and licenses permit modification. The Company distributes its software offerings under open source licenses that permit access to the software's human-readable source code. The Company provides its software offerings primarily under annual or multi-year subscriptions as well as on-demand through cloud service providers.
