A healthcare enterprise is building a hybrid cloud network to connect its primary on-premises electronic health record (EHR) data centers to a Google Cloud Virtual Private Cloud (VPC). The connection must support a sustained throughput of 20 Gbps, guarantee a 99.99% availability SLA, and provide dynamic failover using BGP across redundant physical paths. Which TWO architecture steps are required to achieve this configuration in accordance with Google Cloud best practices?
- Provision four Dedicated Interconnect circuits deployed across two distinct Google Cloud edge availability domains (colocation facilities).Answer
- Configure two Cloud Routers in the target VPC network, establishing redundant BGP sessions for attachments in both edge locations.Answer
- CDeploy an High Availability (HA) Cloud VPN gateway with four active IPsec tunnels over public internet connections to achieve the 20 Gbps throughput requirement.
- DEstablish VPC Network Peering between the on-premises gateway hardware and the Google Cloud VPC network to allow transitive BGP route distribution.
- EConfigure a VPC Service Controls perimeter bridge between regions to manage physical path redundancy and execute BGP failover actions.
Answer
To establish a 99.99% availability SLA for high-throughput hybrid connectivity, provision four Dedicated Interconnect circuits across two distinct colocation edge locations and configure two Cloud Routers in the VPC network to manage redundant BGP sessions.
The production SLA for 99.99% availability using Dedicated Interconnect mandates four physical circuits split equally across two different Google Cloud edge colocation facilities (availability domains). Furthermore, dynamic routing via Cloud Routers terminating BGP sessions across both facilities is required to handle automatic failover and load balancing.
