Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in 2001. The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical server, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS; however, due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.
While Dedicated Server Hosting offers isolated hardware, where resources such as disk input/output and host network connections are not shared, it also requires a significant upfront investment and a higher level of technical capability to manage it. With VPS Hosting, you share a server with other customers, but remain isolated from those other users on the server. With Virtual Private Server Hosting you are granted your own section of a partitioned dedicated server with a guaranteed threshold of dedicated RAM, storage and bandwidth and have the ability to customize this partition, much like a dedicated server. VPS Hosting provides a more cost-effective and scalable option for growing businesses when compared to Dedicated Server Hosting. On the other hand, with Shared Hosting you share a portion of the server with other users, potentially affecting your output if other users on the same server are experiencing high traffic.

You can move corporate applications to the cloud, launch additional web servers, or add more compute capacity to your network by connecting your VPC to your corporate network. Because your VPC can be hosted behind your corporate firewall, you can seamlessly move your IT resources into the cloud without changing how your users access these applications. You can select "VPC with a Private Subnet Only and Hardware VPN Access" from the Amazon VPC console wizard to create a VPC that supports this use case.
Shared hosting: With shared hosting, your site is stored and served from the same physical machine as many other customers – possibly hundreds of them. All domains are drawing from the same CPU, RAM, and other resources. This type of hosting is the lowest-priced option. However, your site’s speed and reliability suffer from other users, and you don’t get root access.
A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.
