A
BSTRACT
 
Context: 
Cloud computing offers enterprises a method to access computing resources 
on-demand. This allows enterprises to save on capital expenses related to periodic 
hardware upgrades, maintenance and energy costs. However data traversing in cloud, 
leads to data breaching and data loss by third party intruders affecting the managing and 
reliability of sensitive information. A virtual private network, VPN, is a typical way of 
interconnecting networks over a public network infrastructure securing data transferred 
across the private subnets. The goal of this project is to provide VPN as a service using 
virtualized VPN software, essentially making the VPN yet another building block for a 
service in the cloud.
