Amazon SQS (Simple Queue Service) Decoupling

Amazon SQS is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications.

Queue Types

SQS offers two types of message queues: Standard queues for maximum throughput and best-effort ordering, and FIFO queues for exactly-once processing and strict ordering.

Decoupling Benefits

SQS eliminates the complexity and overhead associated with managing and operating message-oriented middleware. You can send, store, and receive messages between software components at any volume.

Message Processing

SQS provides visibility timeout, which prevents other consumers from receiving and processing a message during the timeout period. After the timeout expires, the message becomes visible again.

SQS Glossary

Standard Queue
A queue type that provides maximum throughput, best-effort ordering, and at-least-once delivery. Ideal for high-throughput scenarios.
FIFO Queue
A queue type that provides exactly-once processing, strict message ordering, and limited throughput (300 TPS per queue).
Visibility Timeout
The period during which SQS prevents other consumers from receiving and processing a message. After the timeout expires, the message becomes visible again.
Dead-Letter Queue (DLQ)
A queue that handles messages that cannot be processed successfully after a specified number of attempts.
Long Polling
A feature that reduces the number of empty responses by allowing SQS to wait up to 20 seconds for a message to become available before sending a response.
