Pattern description

Open-source software is widely used both as independent applications and as components in non-open-source applications. Many independent software vendors (ISVs), value-added resellers (VARs), and hardware vendors (OEMs or ODMs) use open-source frameworks, modules, and libraries inside their proprietary, for-profit products and services. From a customer's perspective, the ability to use open technology under standard commercial terms and support is valuable. They are willing to pay for the legal protection (e.g., indemnification from copyright or patent infringement), "commercial-grade QA", and professional support/training/consulting that are typical of commercial software, while also receiving the benefits of fine-grained control and lack of lock-in that comes with open-source.
