EHR Healthcare is transitioning from colocation facilities to Google Cloud to scale their environment, improve disaster recovery, and enhance continuous deployment capabilities. The company's customer-facing applications are web-based and containerized, running on Kubernetes clusters with data stored in relational and NoSQL databases. They require a minimum 99.9% availability for all systems, a secure and high-performance connection between on-premises systems and Google Cloud, and centralized visibility for system performance and usage. Given these requirements, how should you define the technical architecture for hybrid connectivity between EHR's on-premises systems and Google Cloud, following Google's recommended practices for production-level applications?
Exam-Like
A
Configure two Partner Interconnect connections in one metro (City), and make sure the Interconnect connections are placed in different metro zones.
B
Configure two VPN connections from on-premises to Google Cloud, and make sure the VPN devices on-premises are in separate racks.
C
Configure Direct Peering between EHR Healthcare and Google Cloud, and make sure you are peering at least two Google locations.
D
Configure two Dedicated Interconnect connections in one metro (City) and two connections in another metro, and make sure the Interconnect connections are placed in different metro zones.
Explanation:
The correct answer is D. EHR Healthcare needs a high-performance, secure, and low-latency connection between their on-premises systems and Google Cloud. Google's recommended practice for production-level applications includes configuring multiple Dedicated Interconnect connections for redundancy and reliability. By configuring two Dedicated Interconnect connections in one metro and two in another metro, placed in different metro zones, EHR can achieve the required 99.9% availability and ensure resilience against regional failures. This setup aligns with Google's best practices for creating a robust and fault-tolerant architecture.
