Analysis of Zonda, Workday's proprietary AI-centric data streaming platform, built upon Apache Flink. It highlights Zonda's crucial role as the central nervous system for data powering Workday's advanced Artificial Intelligence and Machine Learning capabilities. The report examines the strategic decision behind building Zonda in-house, citing the inadequacy of generic cloud services to meet Workday's stringent demands for low latency, cost-efficiency, and multi-tenant data security.

Furthermore, it details specific engineering challenges overcome by the Zonda team, such as implementing cryptographic isolation for multi-tenancy and optimizing S3 writing performance, underscoring Workday's deep technical expertise and the platform's strategic competitive advantage.
