OpenStack 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.

Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.

With the CoreCluster you can create private clouds, like Amazon’s EC2, but based on your own hardware. All what is necessary is some hardware with Ubuntu or Debian operating systems. Users can create theirs own virtual machine instances and manage whole virtual environment, without any hardware reconfiguration. Software supports many additional modules, which extends its base functionality.
