Zato is an ESB (Enterprise Service Bus) which is written in Python. It is free and open source (LGPL).
http://en.m.wikipedia.org/wiki/Enterprise_service_bus
Tibco was one of the first ESB products and Mule is an open source one.
According to the Zato site:
It supports HTTP, JSON, SOAP, Redis, JMS WebSphere MQ, ZeroMQ, FTP, SQL.
It has a web admin GUI, a CLI and an API.
Documentation and commercial support are available.
I got to know about Zato recently from the main developer, Dariusz Suchojad, who had earlier written to me regarding my blog post about PyMQI:
PyMQI, Python interface to IBM WebSphereMQ (formerly IBM MQSeries):
http://jugad2.blogspot.com/2013/02/pymqi-python-interface-to-ibm.html
Dariusz was a maintainer of PyMQI and also a developer on Spring Python, which is sort of a port of the Java Spring framework to Python.
Zato docs (quite detailed):
https://zato.io/docs/index.html
Part 1 of a basic Zato tutorial:
https://zato.io/docs/tutorial/01.html
I took a look at the tutorial. Broadly, it shows how to install Zato, create a simple Zato service in Python, that talks to PostgreSQL and Redis, and deploy it. Two servers get created, behind a load-balancer, and the service gets hot-deployed to the servers. Then curl is used to access the service. (This tutorial does not create a real client; curl is used to simulate one.)
Zato looks interesting and powerful (and somewhat complex, but that is to be expected for a product like an ESB).
I will check it out more and then report on my findings.
