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.
Collage is a cross-platform C++ library for building heterogenous, distributed applications. Among other things, it is the cluster backend for the Equalizer parallel rendering framework. It provides an abstraction of different network connections, peer-to-peer messaging, node discovery, synchronization, and high-performance, object-oriented, versioned data distribution. It is designed for low-overhead multi-threaded execution, which allows applications to easily exploit multi-core architectures.
Xenograte Community Toolkit is based on Xenograte, a platform which enables users to manage and orchestrate worker processes, and easily design the flow of data shared among them. Xenograte works either on one server or across multiple servers/clouds. The Toolkit provides a CLI and other resources for building, testing, and debugging worker processes, in Ruby, on a single machine. You can then easily weave these worker processes together into powerful integrations or automations.
