What method is used to achieve private, low-latency network interconnectivity between a corporate data center and cloud operations?

The method used to achieve private, low-latency network interconnectivity between a corporate data center and cloud operations is a dedicated private connection. This option is ideal for organizations that require secure and reliable connectivity to their cloud resources.

Dedicated private connections, such as AWS Direct Connect or Azure ExpressRoute, establish a direct link between a corporate data center and cloud services, bypassing the public internet. This setup not only reduces latency significantly compared to public internet connections but also enhances security, as data does not traverse the public web where it could be vulnerable to interception or attacks.

In contrast, a public internet connection is susceptible to latency issues and security risks due to its unregulated nature. A shared VPN may offer some level of encryption but does not guarantee the same performance and reliability as a dedicated service, as multiple users may share the network resources leading to variable performance. A cloud gateway, while useful for accessing cloud services, does not specifically provide the low-latency, secured, and dedicated path that a private connection can offer, thus making it less suitable for this scenario.
