Watson developer cloud delivers Watson Cognitive services as micro services on the cloud that are being used by many IBM Watson customers. The micro services were packaged in ova at the first release. There were some drawbacks in ova deployment in the cloud. We gradually switched to use docker. As a result, the service deployment time and start up time are significantly improved. It also greatly simplified our continuous delivery process since our services run on both Intel and Power platform and we have offerings on our public cloud, dedicated cloud as well as customers’ on premise cloud. With minimal deployment time and quick startup time, Docker makes our dynamic creation of service instance on the fly per customer request possible
