Connectivity for transferring data from Azure to GCP

@Nikunj Patel ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

You can establish connectivity to other cloud providers via 2 ways

• S2S VPN - Traffic goes over Public Internet and is encrypted (no security compromise)
• ExpressRoute - Traffic goes over Private Dedicated Path but is not encrypted

The major advantage of ExpressRoute over S2S is the throughput as the physical path is dedicated to you and there is no overhead of encryption.

With S2S, the advantage is that this is easier to set up compared to ExR where a Service Provider (ISP) is required.

You can find more details here : Connectivity to other cloud providers.
