IBM's approach to open technology
For several years, IBM has been recognized as a leader in open technology, from its early work with Apache to its current work across all layers of the cloud stack and application development. This recognition comes on the back of tireless collaboration with fellow industry leaders and clients alike. The case for open is clear: Projects that are managed under open governance have been found to be more successful, have a longer life, and are less risky than proprietary projects. The most successful projects are those that ensure interoperability and portability, and address various other enterprise needs such as security, scalability, and accessibility. IBM isn't just an open source consumer; it is also an ardent contributor to several projects, including Eclipse, Linux, OpenStack, Cloud Foundry, Node.js, Docker, Hyperledger, and many more. The company's ongoing commitment to open technology is viewed as a means to form the very foundation of enterprise systems and solutions.
