A company is migrating applications from a data center to AWS. Many of the applications will need to exchange data with the company's on-premises mainframe. The company needs to achieve 4 Gbps…

While effective, four 10 Gbps connections are over-provisioned and more expensive than necessary to meet a 4 Gbps requirement with high availability, as two 10 Gbps connections suffice.

Ordering two 10 Gbps Direct Connect connections across two different Direct Connect locations provides 20 Gbps total bandwidth, comfortably exceeding the 4 Gbps peak demand, and offers high availability and resiliency against single circuit or location failures.

Four 1 Gbps connections provide exactly 4 Gbps total bandwidth but offer limited failover capacity, as the loss of a single connection could reduce bandwidth below the peak demand, and they do not match the resiliency of 10 Gbps links.

Two 1 Gbps connections provide only 2 Gbps total bandwidth, which is less than the required 4 Gbps peak transfer speed, making this option insufficient to meet performance requirements.
