Question

A financial services company is migrating a latency-sensitive trading analytics workload to Azure. Requirements include: a consistent 5 Gbps of throughput, BGP-based dynamic routing between on-premises and Azure, redundancy across two physically diverse paths at the peering location, and the ability to advertise the same on-premises prefixes over both paths for active/active load distribution. Which connectivity design best satisfies these network architecture requirements?

Accepted Answer

An ExpressRoute circuit provisioned with a 5 Gbps port, using the built-in dual BGP peerings across the two redundant physical connections at the peering location

Answer

A single site-to-site IPsec VPN over the internet using BGP, sized with multiple tunnels to aggregate bandwidth

Answer

Two independent ExpressRoute circuits at the same peering location with static routing configured to each Azure VNet gateway

Answer

A single ExpressRoute circuit with Microsoft peering only, relying on ECMP toward SaaS endpoints for redundancy
