In Azure Databricks environments that rely on Private Link for secure networking, it’s common to route traffic through multi-tiered network architectures. This often includes multiple VNets, Private Link endpoints, or peered subscriptions between data sources (e.g., ADLS) and the Databricks compute plane. While these architectures may be designed for isolation or compliance, they frequently introduce redundant routing paths that add cost without improving performance. Each additional hop may result in duplicated Private Link ingress and egress charges. Without regular review, this can create persistent and unrecognized network inefficiencies tied to Databricks usage.
