If you are wondering if it is possible to setup a private cloud infrastructure (similar to AWS) , the answer is YES.
If you have a computer (laptop or desktop) with very good configuration as mentioned below, you can have your OWN Private Cloud Infrastructure set up on your computer using Eucalyptus, open source private cloud software.
Interesting thing about Eucalyptus is it is AWS Compatible.
CPU: 64 Processor(s) with multiple cores
Hard disk: SSD hard drive for better performance
Software: Virtualization software like VMWare Workstation
Even if you have slightly lower configuration also it is still possible to setup your cloud intrastructure, but the performance might be slow.
