PC = Personal Cloud (or how to use your development machine with Vagrant and Virtual Box for good)
The document presents an overview of cloud computing and its components, particularly focusing on Infrastructure as a Service (IaaS) and related technologies like VirtualBox and Vagrant. It outlines the evolution of processors, the use of virtualization in computing, and practical steps for setting up a personal cloud environment. Multiple tools and resources, including links to documentation, are provided to assist in understanding and implementing these technologies.
