Amazon SQS vs RabbitMQ: What are the differences?
Amazon SQS: Fully managed message queuing service. Transmit any volume of data, at any level of throughput, without losing messages or requiring other services to be always available. With SQS, you can offload the administrative burden of operating and scaling a highly available messaging cluster, while paying a low price for only what you use; RabbitMQ: A messaging broker - an intermediary for messaging. RabbitMQ gives your applications a common platform to send and receive messages, and your messages a safe place to live until received.
Amazon SQS and RabbitMQ can be categorized as "Message Queue" tools.
Some of the features offered by Amazon SQS are:
- A queue can be created in any region.
- The message payload can contain up to 256KB of text in any format. Each 64KB ‘chunk’ of payload is billed as 1 request. For example, a single API call with a 256KB payload will be billed as four requests.
- Messages can be sent, received or deleted in batches of up to 10 messages or 256KB. Batches cost the same amount as single messages, meaning SQS can be even more cost effective for customers that use batching.
On the other hand, RabbitMQ provides the following key features:
- Robust messaging for applications
- Easy to use
- Runs on all major operating systems
"Easy to use, reliable" is the primary reason why developers consider Amazon SQS over the competitors, whereas "It's fast and it works with good metrics/monitoring" was stated as the key factor in picking RabbitMQ.
RabbitMQ is an open source tool with 5.94K GitHub stars and 1.78K GitHub forks. Here's a link to RabbitMQ's open source repository on GitHub.
According to the StackShare community, RabbitMQ has a broader approval, being mentioned in 940 company stacks & 548 developers stacks; compared to Amazon SQS, which is listed in 384 company stacks and 103 developer stacks.
