• →Own infrastructure for data + AI workloads (containers, orchestration, cloud services)
• →Enable self-serve data workflows for engineering and product teams
• →Improve observability, reliability, and performance across the data stack
• →Support AI/ML systems (embeddings, vector data, model pipelines)
