A Virtual Private Server is created by partitioning the physical server into multiple mini servers, made possible by the technology of Server Virtualization. The term Virtual Server is widely used by Internet hosting services and it is often used to refer a Virtual Machine. A Virtual Private Server VPS works in a federated environment used by other virtual machines. But in all aspects the functionality is equivalent to that of an environment created by a physical computer dedicated to individual customer needs. It offers the same privacy, which is seen in separate physical computer environment, configured to run server software. Virtual Private Servers are also known with the synonyms Virtual Root Server VRS and Virtual Dedicated Server VDS.
You can use Amazon VPC to host multi-tier web applications and strictly enforce access and security restrictions between your webservers, application servers, and databases. You can launch webservers in a publicly accessible subnet and application servers and databases in non-publically accessible subnets. The application servers and databases can’t be directly accessed from the Internet, but they can still access the Internet via a NAT gateway to download patches, for example. You can control access between the servers and subnets using inbound and outbound packet filtering provided by network access control lists and security groups. To create a VPC that supports this use case, you can select "VPC with Public and Private Subnets" in the Amazon VPC console wizard.
Amazon VPC provides advanced security features, such as security groups and network access control lists, to enable inbound and outbound filtering at the instance level and subnet level. In addition, you can store data in Amazon S3 and restrict access so that it’s only accessible from instances in your VPC. Optionally, you can also choose to launch Dedicated Instances which run on hardware dedicated to a single customer for additional isolation.
Your web projects come in all shapes and sizes. Shouldn't your VPS meet your needs more closely? Your project may need additional disk space or data transfer while maybe you don't need so much RAM. Don't get stuck paying for for resources you don't want or don't need from a one-size-fits-all VPS provider. We've got your covered! Design your perfect VPS at A2 Hosting! 
You're an experienced developer who wants full control over your environment. We're giving it to you! You get root access so you're able to access and edit all of your server's files! You get to choose your Linux OS and can even re-load your server with a new operating system on demand! You also get boot, shutdown and reboot control. Now we're talking about serious hosting!
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.
f. In a few minutes, the Instance State column on your instance will change to "running" and a Public IP address will be shown. You can refresh these Instance State columns by pressing the refresh button on the right just above the table. Copy the Public IP address of your AWS instance, so you can use it when we connect to the instance using SSH in Step 4.
Most people are clueless about the virtual servers hosting and how they actually work on the shared environment. It is a known fact that thousand and more number of users tend to use a server at a time. In such circumstances, each user is allocated with a designated amount of disk space, bandwidth, CPU allocation, memory and Operating System, which can be used on the server. All the Virtual Private Server users share the same CPU and RAM and think that, they have dedicated set of hardware. Virtual Server software is loaded onto the physical system and from then, a virtual server is ready to be used.
OpenVZ virtualization is an OS level container-based virtualization, and it has resources that are divided between users on a physical server. Each container acts like a stand-alone virtual server and can be accessed with a root (SSH) connection. As a separate server container can be rebooted separately, it also has a dedicated IP address, shared RAM, individual processes, files, applications, system libraries and configuration files. On OpenVZ, the kernel cannot be modified. It has its stable version and modules cannot be added. The good thing regarding this virtualization is a faster performance, and a lower need of resources.

With unmanaged VPS hosting, the cost is also much cheaper. It is not uncommon to find $10 unmanaged VPS plans because the web host does not have to pay for a cPanel or Plesk license and are able to minimize costs. Also, since the web host does not provide software and account support for an unmanaged VPS, the host also saves money on customer support. In the end, you'll have VPS hosting that is typically $20-30 cheaper than a managed VPS solution.

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.[1]
