Open-source software (OSS) underpins all major cloud platforms and a large number of cloud-based services today. Core technologies that power cloud computing –Linux, Kubernetes, Cloud Foundry, Docker, to name a few –are developed in open communities. The Cloud Native Computing Foundation supports innovation in OSS for cloud computing and has sponsorship and participation from practically all major players in the cloud ecosystem.
A recent survey  of 3,440 professional developers and managers showed the widespread influence of open source, both in cloud technology and as an essential in-demand and growing skill in the industry. For example, 69% of respondents thought that contributions to open-source projects result in better professional opportunities.
