AWS Serverless Microservices with Patterns and Best Practices - Amazon SQS Queue Types - Standard Queues and FIFO Queues

The video tutorial explains Amazon SQS queue types: standard and FIFO. Standard queues offer unlimited throughput, best-effort ordering, and at least once delivery, but may deliver duplicate messages. FIFO queues ensure first-in-first-out ordering and exactly-once delivery, with limited throughput. The tutorial compares these queues based on message ordering, delivery guarantees, and throughput, highlighting their use cases. Standard queues are suitable for applications that can handle duplicates and out-of-order messages, while FIFO queues are ideal for scenarios requiring strict message order and no duplicates.
