Ray is an open-source distributed compute framework developed at UC Berkeley's RISELab that enables users to run Python code in a parallel fashion across multiple machines. It provides a general-purpose clustering and parallelization framework that can be used to build and run any type of distributed application. Ray allows users to focus on building their ML use case, not distributed technologies. Arize is an ML observability platform that helps ML practitioners tackle issues such as model performance degradation, data drift, and data quality issues in real-time. Arize provides automated monitoring, strong troubleshooting workflows, and is built for scale, intuition, and ease of use. By combining Ray and Arize, users can offload tasks such as distributed computing and model monitoring to technology, freeing up time to focus on building high-value ML models using deep business domain knowledge.
