Zato is an Enterprise Service Bus (ESB) and app server written by pragmatists for pragmatists. It provides an HA load-balancer, hot-deployment, and hot-reconfiguration almost everywhere (forget server restarts). It has a browser-based GUI, CLI, and API (forget XML configuration). It supports many protocols, industry standards, and data formats, including HTTP, JSON, SOAP, REST, AMQP, JMS WebSphere MQ, ZeroMQ, Redis, SQL, and FTP.
python-fedex is light wrapper for Fedex's Web Services SOAP API. The intent is to stay out of the way of the developer as much as possible, while handling some of the more repetitive and mundane portions of forming and sending SOAP requests. The module makes use of the excellent suds package along with Python versions 2.5 and up, but not yet Py3K.
