That's a good question. The features supported by AMQP brokers, ZMQ, and Marconi certainly do overlap in some areas. At the same time, however, each of these options offer distinct features that may or may not align with what a web developer is trying to accomplish.

Here are a few of Marconi's unique features, relative to the other options you mentioned:

  *  Multi-tenant
  *  Keystone integration
  *  100% Python
  *  First-class, stateless, firewall-friendly HTTP(S) transport driver
  *  Simple protocol, easy for clients to implement
  *  Scales to an unlimited number of queues and clients
  *  Per-queue stats, useful for monitoring and autoscale
  *  Tag-based message filtering (planned)

Relative to SQS, Marconi:

  *  Is open-source and community-driven
  *  Supports private and hybrid deployments
  *  Offers hybrid pub-sub and producer-consumer semantics
  *  Provides a clean, modern HTTP API
  *  Can route messages to multiple queues (planned)
  *  Can perform custom message transformations (planned)

Anyway, that's my $0.02 - others may chime in with their own thoughts.
