What benefit do low-latency links between Availability Zones provide?

Low-latency links between Availability Zones enhance fault tolerance by enabling applications to seamlessly failover to another zone in the event of a failure. This interconnectedness ensures that data replication, backup processes, and application availability remain uninterrupted even when issues arise in one zone. Low-latency communication allows services to synchronize quickly, meaning any failures can be mitigated rapidly, thereby maintaining higher levels of uptime and performance for critical applications.

In contrast, while faster backup times and increased file transfer speeds are advantageous, they are not the primary benefits directly linked to the concept of low-latency connections between Availability Zones. Improved data security may be a consideration in overall architecture but is not specifically a direct outcome of the low-latency connections. Instead, the focus is on maintaining operational continuity and resilience through effective resource availability across different zones.
