AWS SQS Fair Queues: Mitigating Noisy Neighbors in Multi-Tenant Systems

AWS introduced Amazon SQS fair queues, a new feature designed to mitigate the impact of 'noisy neighbors' in multi-tenant systems. Noisy neighbors are tenants that overuse resources, causing delays for others. Fair queues monitor message distribution and automatically adjust delivery order, prioritizing messages from non-noisy tenants. This ensures consistent service quality for all tenants without requiring changes to existing message processing logic. Developers simply add a tenant identifier (MessageGroupId) and monitor relevant metrics using CloudWatch.
