Title: Upstream's Journey to Continuous Deployment
Upstream decided a few years ago to enroll in a CD program and then an amazing journey for the company begun, which will be presented within the framework of this presentation.
Key reasons behind this decision will be demonstrated followed by the appropriate tool selection and the needed organization transformations. The challenges have just started. The roll-out of the program especially for the legacy products was the first challenge we needed to address in parallel with the ongoing mentality shift of the engineering organization. Subsequently, the impact of the CD program in both qualitative and quantitative in Upstream business will be presented.

 Finally, valuable lessons learned out of this journey will be presented.
