7 . Nature of the OSS • If you would develop your product or service, you may face lacked feature/instability in the OSS • Someone developed for their business – Very well tested for his businesses – May not take care about other business • Almost no difference against proprietary software – Vendor assumes workload and test cases for it – You can request lacked feature to vendor/community Copyright 2018 FUJITSU LIMITED 

8 . Difference between OSS & ISV • You may request lacked feature to the project – Add your requirement to To-Do List in community – A person who understands your business may develop it • You can directly pay cost for the development – There should be source code Copyright 2018 FUJITSU LIMITED 

9 .Copyright 2018 FUJITSU LIMITED OSS as Opened Source Software To release your product/service with dead line • Most likely: Develop platform only in downstream – Fork source code from upstream – Add required features to the forked code • You have to maintain forked source code – Keep it healthy: Backport more than 100 CVEs to your platform – Keep adding new features: Keep maintaining your own fixes Copyright 2018 FUJITSU LIMITED
