What network feature in Google Cloud provides a high-throughput connection between a customer's VPC network and NetApp Cloud Volumes Service?

The high-throughput connection between a customer's VPC network and NetApp Cloud Volumes Service is facilitated by Private Services Access. This feature allows customers to connect their Virtual Private Cloud (VPC) networks to Google Cloud services, such as Cloud Volumes Service, over a private and secure connection. This is crucial for maintaining the performance and reliability of the connection, ensuring that data can be transferred quickly without traversing the public internet, which can introduce latency and security issues.

Private Services Access provides a simplified way to access services in Google Cloud directly, allowing users to establish a private connection that benefits from the scalability and performance of Google’s infrastructure. It supports configurations where consumers can access services with no public IP addresses, ensuring that traffic remains within Google's network.

In contrast, the other options involve different types of connections that may not specifically provide the necessary high-throughput and private connectivity required for integrating with Cloud Volumes Service. Each of those alternatives serves specific use cases but does not directly match the requirements for such an optimized connection in this context.
