Professional Cloud Security EngineerConfiguring network securityMedium
A global enterprise uses Google Cloud and has several VPC networks across different regions. They want to allow secure, private communication between services in one VPC network and a managed service provided by a third party (e.g., a SaaS provider) without exposing traffic to the public internet. The third-party service is also hosted on Google Cloud. Which Google Cloud networking product should they use to achieve this?
- ACloud Interconnect
- BVPC Network Peering
- CPrivate Service Connect
- DCloud VPN
Show answer & explanationAnswer & explanation
Correct answer: C. Private Service Connect
Private Service Connect allows private connectivity to managed services across VPC networks, even across different organizations, without using external IP addresses or traversing the public internet. This perfectly fits the requirement for secure, private communication with a third-party managed service.
Why the other options are wrong
- A. Cloud Interconnect connects on-premises networks to Google Cloud, which is not relevant for connecting to a managed service within Google Cloud.
- B. VPC Network Peering connects two VPC networks directly, primarily for internal communication between an organization's own VPCs, not for consuming third-party managed services securely and privately.
- D. Cloud VPN provides encrypted tunnels over the public internet, which doesn't meet the 'without exposing traffic to the public internet' requirement for private service access.
Private Service Connect
A Google Cloud networking product that allows private consumption of managed services across VPC networks, ensuring traffic remains within Google's network.
- Enables private connectivity to services (Google-managed, partner, or custom).
- Traffic does not traverse the public internet.
- Supports both service producers and consumers across different organizations.
Memory trick: Private Service Connect, like a secret handshake, links your cloud to another's service, no public eyes allowed.
