Cloud Integration and Hybrid Network Architecture Questions

Designing connectivity and integration between on premise infrastructure and public cloud environments, including hybrid and multi cloud topologies. Topics include dedicated interconnect options and internet based connectivity, routing and network topology trade offs, virtual private networks and software defined wide area networks, network virtualization, security boundary and identity considerations across environments, latency and throughput implications, cost trade offs for interconnects, and operational practices for managing hybrid infrastructure and multi cloud complexity.

Describe how you would persuade a client's security and compliance teams to accept a managed dedicated interconnect rather than internet VPN, addressing encryption proofs, auditability, vendor lock-in, and how you'd run a pilot to validate controls.

A small e-commerce company has an on-prem datacenter and wants a low-cost hybrid DR architecture into AWS. They expect 500 Mbps burst traffic during peaks, require encrypted backups, and need RTO < 2 hours. Propose a high-level connectivity and replication approach (initial seeding, ongoing transfer), and explain trade-offs between internet VPN and opening a dedicated connection later.

As a Solutions Architect, compare dedicated interconnect options (e.g., AWS Direct Connect, Azure ExpressRoute, GCP Dedicated Interconnect) versus internet-based VPNs for hybrid connectivity. Discuss throughput, latency, SLA/predictability, security, operational complexity, and cost trade-offs. Provide guidance on which to choose for predictable high-volume data versus low-volume ad-hoc traffic.

Propose an operational plan for detecting and mitigating network incidents across a multi-cloud hybrid infrastructure. Include which telemetry to collect (flow logs, SNMP, telemetry streaming), synthetic tests, SLA/SLI definitions, runbooks for common failures, escalation matrix, and integration with vendor support.

You need to build a cost model comparing Dedicated Interconnect and Internet VPN for moving 10 TB/month to the cloud. List all cost components (port charges, cross-connect, egress fees, hardware, management), explain how to model monthly TCO, and describe what usage patterns or thresholds would shift the recommendation to a dedicated interconnect.
