Users of Shared hosting all share the resources on the server their websites are on. There is no guarantee of RAM or CPU with Shared hosting. Shared hosting also does not provide full root access to the server, as opposed to VPS package where users are given full root access to perform commands and make configuration changes to their hosting environment.
You can create a VPC where instances in one subnet, such as web servers, communicate with the Internet while instances in another subnet, such as application servers, communicate with databases on your corporate network. An IPsec VPN connection between your VPC and your corporate network helps secure all communication between the application servers in the cloud and databases in your data center. Web servers and application servers in your VPC can leverage Amazon EC2 elasticity and Auto Scaling features to grow and shrink as needed. You can create a VPC to support this use case by selecting "VPC with Public and Private Subnets and Hardware VPN Access" in the Amazon VPC console wizard.
One of the tools included with your Managed VPS within cPanel is Softaculous Free. Softaculous is another reason why these plans are easy to use. With Softaculous, you can setup software ranging from blogs to forums to CMS solutions all with a single click of your mouse. As the Premium Hosting partner for PrestaShop, you can also setup this popular eCommerce software with 1-click as well.

Let's take Cloudrino as an example. This Indian startup claims to give you a free VPS. To get it, you need to stay in line - the issue is, the line has apparently, over 230 thousand users in it. And it's not moving very fast! However, to get ahead of the line, you can invite your friends to join the line as well. Like that, you can jump some positions.
