Zilliz commercializes Milvus, an open-source vector database, for AI workloads at scale. The company's tech stack spans distributed storage (CockroachDB, Spanner, Aurora), stream processing (Kafka, Flink, Spark), and orchestration (Kubernetes, Ray), revealing an infrastructure-heavy architecture designed to handle unstructured data pipelines. Sales-led hiring (8 of 13 active roles) paired with projects around SRE tooling and reliability engineering suggests a shift from product-market fit toward enterprise operational maturity.
