Ocado Technology is providing a full solution to put the world’s retailers online using the cloud, robotics, AI and IoT. Processing tens of thousands of orders every day, we generate millions of events every minute, leading to huge amount of data to be managed. We will present how this Big Data is handled in Google Cloud Platform to build a end-to-end machine learning pipeline: how data is stored and processed in BigQuery, post-processed and copied with Dataflow, then used to train Deep Neural Network models with TensorFlow, how all this is orchestrated using our in-house scheduling software called Query Manager, and how predictions are finally run in real-time using Cloud ML Engine and Datastore.
