You need to build a backup replica of a 4 TB on‑prem PostgreSQL with frequent large updates and require private address space connectivity. Which networking option should you use?

Dedicated Interconnect provides a direct, private connection to Google Cloud, offering high bandwidth and low latency, which is essential for replicating a 4 TB database with frequent large updates. This ensures efficient and timely synchronization without traversing the public internet. Google Cloud VPN, while providing private connectivity, typically offers lower bandwidth and higher latency compared to Dedicated Interconnect, making it less suitable for such a large and frequently updated database. A NAT and TLS translation gateway on-premises doesn't address the underlying network connectivity requirements for high-volume data transfer. A Compute Engine instance with a VPN server would also suffer from similar bandwidth and latency limitations as Cloud VPN and adds management overhead.
