Customers are reporting very high latencies when accessing an application from the United States. The application is currently running in a single region in Europe. What should the organization do?

Billing accounts are administrative constructs that have no effect on application performance or network latency.

Adding zones within the same European region improves availability and fault tolerance but does not reduce latency for users in the United States.

Running in additional European regions still keeps the application far from US users and does not reduce the geographic distance causing high latency.

Deploying a replica of the application in a US region places compute resources geographically close to US users, dramatically reducing round-trip network latency. This is the standard approach to solving cross-continental latency problems in cloud architectures.
