What happens if you create an Amazon SQS queue in one AWS region?

The correct answer emphasizes that when you create an Amazon SQS queue in a specific AWS region, that queue operates independently from queues in other regions. Each AWS region serves as a distinct geographic area with its own resources and services. This independence means that any configurations, messages, or attributes associated with the queue are confined to that particular region.

For instance, if you have a queue in the US East (N. Virginia) region and wish to create another queue in the Europe (Frankfurt) region, both queues are managed separately. Each region maintains its own data and logic, and any messages stored in one queue in a specific region don't automatically share or replicate to other queues in different regions.

While accessing the queues might be limited based on certain conditions, their independence is the fundamental characteristic that distinguishes AWS resources across regions. This design enhances the robustness of AWS services, allowing applications to be architected in a manner that caters to specific regional compliance, latency, and availability requirements.
