OpenStack is a global collaboration of developers and cloud computing technologists producing the ubiquitous open source cloud computing platform for public and private clouds. The project aims to deliver solutions for all types of clouds by being simple to implement, massively scalable, and feature rich. The technology consists of a series of interrelated projects delivering various components for a cloud infrastructure solution.

The Floodlight controller is an enterprise-class, Apache-licensed, Java-based OpenFlow Controller. It is supported by a community of developers including a number of engineers from Big Switch Networks.

OpenFlow is a open standard managed by the Open Networking Foundation (ONF).  It specifies a protocol through switch a remote controller can modify the behavior of networking devices through a well-defined “forwarding instruction set”.  Floodlight is designed to work with the growing number of switches, routers, virtual witches, and access points that support the OpenFlow standard.

Storm is a free and open source distributed realtime computation system. Storm makes it easy to reliably process unbounded streams of data, doing for realtime processing what Hadoop did for batch processing. Storm is simple, can be used with any programming language, and is a lot of fun to use!
