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.
Ebot is a scalable and distribuited Web crawler. The URLs are saved to a NOSQL database (which supports map/reduce queries) that you can query via RESTful HTTP requests or using your preferred programming languages. The URLs that need to be analyzed are sent to AMQP queues. In this way, it is possible to run several crawlers in parallel and stop and start them without losing URLs.
pyBit uses AMQP to create a distributed, cross-platform buildd toolkit to build packages using a collection of buildds, direct from various VCS clients. It is intended to support rapidly evolving software collections, and can support multiple VCS frontends and multiple build backends. Cross building is expected to be supported for some backends. The initial backend uses dpkg for Debian. pyBit includes support for cancelling selected builds and using multiple buildd clients per architecture, per platform, and per suite.
Apache Qpid is a messaging broker that implements the latest AMQP specification, providing transaction management, queuing, distribution, security, management, clustering, federation, heterogeneous multi-platform support, and much more. It is extremely fast and aims to be 100% AMQP Compliant.
The Clacks Framework enables implementators to abstractly manage infrastructure entities, such as users, groups, machines and structure items. These are freely defineable and mappable to various backends like LDAP or MongoDB. Additionally it can handle joined clients, collect inventory data, and manage these clients in various ways. All information, API, and events are exposed on an AMQP message bus, and can be used by shell scripts, Web GUIs, etc.
