Amazon SQS vs ZeroMQ: 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; ZeroMQ: Fast, lightweight messaging library that allows you to design complex communication system without much effort. The 0MQ lightweight messaging kernel is a library which extends the standard socket interfaces with features traditionally provided by specialised messaging middleware products. 0MQ sockets provide an abstraction of asynchronous message queues, multiple messaging patterns, message filtering (subscriptions), seamless access to multiple transport protocols and more.
Amazon SQS and ZeroMQ 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, ZeroMQ provides the following key features:
- Connect your code in any language, on any platform.
- Carries messages across inproc, IPC, TCP, TPIC, multicast.
- Smart patterns like pub-sub, push-pull, and router-dealer.
"Easy to use, reliable" is the top reason why over 45 developers like Amazon SQS, while over 17 developers mention "Fast" as the leading cause for choosing ZeroMQ.
ZeroMQ is an open source tool with 5.28K GitHub stars and 1.56K GitHub forks. Here's a link to ZeroMQ's open source repository on GitHub.
According to the StackShare community, Amazon SQS has a broader approval, being mentioned in 381 company stacks & 101 developers stacks; compared to ZeroMQ, which is listed in 35 company stacks and 12 developer stacks.

In the beginning we thought we wanted to start using something like RabbitMQ or maybe Kafka or maybe ActiveMQ. Back then we only had a few developers and no ops people. That has changed now, but we didn't really look forward to setting up a queuing cluster and making sure that all works.
What we did instead was we looked at what services Amazon offers to see if we can use those to build our own messaging system within those services. That's basically what we did. We wrote some clients in Ruby that can basically do the entire orchestration for us, and we run all our messaging on both SNS and SQS. Basically what you can do in Amazon services is you can use Amazon Simple Notification Service, so SNS, for creating topics and you can use queues to subscribe to these topics. That's basically all you need for a messaging system. You don't have to worry about scalability at all. That's what really appealed to us.
This isn't exactly low-latency (10s to 100s of milliseconds), but it has good throughput and a simple API. There is good reliability, and there is no configuration necessary to get up and running. A hosted queue is important when trying to move fast.
SQS is the bridge between our new Lambda services and our incumbent Rails applications. Extremely easy to use when you're already using other AWS infrastructure.
Our platform is based on interconnected services with a custom RPC protocol based on ZeroMQ and inspired by ZeroMQs LPP/MDP protocols.
Primary message queue. Enqueueing operations revert to a local file-system-based queue when SQS is unavailable.
I can't afford to lose data if Dynamo throttles my writes, so everything goes into a message queue first.
