What's a good distributed queue?
Hmm, I'm not sure. What about the cost?
Kafka and RabbitMQ are open source software, so you can use them for free. However, you'll need to manage the infrastructure yourself. AWS SQS is a paid service, but it offers a fully managed solution, which means you don't have to worry about the infrastructure. You can choose the pricing tier that best fits your usage patterns.
