Amazon SQS review
A managed AWS queue service with standard and FIFO delivery options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Amazon SQS is a fully managed cloud message queuing service for decoupling microservices, distributed systems, and serverless applications. It is suited to teams building around AWS services and accessing queues through the AWS Management Console, APIs, or AWS SDKs. Standard queues provide at-least-once delivery and best-effort ordering, while FIFO queues add exactly-once processing and ordered message groups for workflows where message sequence matters.
The published plans show a monthly free tier covering 1 million Amazon SQS requests. Beyond that, Standard queues and FIFO queues use usage-based pricing, with costs varying by queue type, AWS Region, request size, and other options. The main product choice is therefore operational rather than feature-gated: Standard queues favor high-volume asynchronous processing with at-least-once delivery, while FIFO queues are intended for ordered message groups and exactly-once processing. Message batching supports up to 10 messages, and long polling can help applications retrieve messages efficiently.
SQS fits especially well into AWS architectures. Integrations include Amazon EC2, ECS, Lambda, SNS, S3, DynamoDB, RDS, and Redshift, while server-side encryption with AWS KMS, queue sharing, and resource-based permissions support controlled access. Dead-letter queues and message redrive help manage messages that cannot be processed successfully, and message retention extends up to 14 days. Choose SQS when managed AWS-native queuing, configurable delivery guarantees, and built-in service integrations are priorities. Consider another message broker when portability across cloud platforms or broader protocol support matters more than AWS ecosystem alignment.
Amazon SQS pros and cons

- Where it doesn't
- Best-effort ordering applies to standard queues
- Usage-based pricing varies by queue type and request characteristics
- Designed for AWS environments rather than broad multi-cloud portability
