The concept of a virtual private server can be better explained as a virtual machine that caters to the individual needs of a user just as a separate physical computer that is dedicated to a particular user. The virtual dedicated server provides the same functionality and privacy as that of a normal physical computer. A number of virtual private servers can be installed on a single physical server with each one running its own operating system.
You'll also want to determine how long you'll need VPS web hosting. If you need hosting for a short time period—say, less than a month or two—you'll typically receive a refund should you cancel your hosting within 60 days. These money-back guarantees vary from web host to web host. For example, Company X may offer a 30-day money-back guarantee, while Company Y may offer a lengthy 90-day money-back guarantee. As always, it's best to shop around for the features that best suit your web hosting needs.
For packages supporting unmetered disk space or data transfer (bandwidth), we do not have defined limitations. These resources are "unmetered", meaning you are not billed according to the amount of disk space or bandwidth used. While of course these resources are not infinite, we believe our customers should have all the resources necessary to build an online presence and 99.95% of customers will have more than enough disk space and bandwidth to meet their needs.
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.
The number of sites that you host on the server, the number of databases or mailboxes are not limited on a VPS, moreover, Hostens does not block any ports. VPS is a separate server that gives its owner the possibility to customize its settings. On shared hosting, you cannot choose any control panel or any software, as the provider has already configured it. As VPS provides full access (SSH) to VPS hosting, the customer is free to install, manage and control any software that is compatible with server virtualization.
Another benefit of virtualizing servers is that they are no longer tied to a hardware platform. This provides the ability to virtually expand or upgrade (upgrade) the hardware platform during operation without significant downtime (~ 1 second downtime). Also, a hardware problem does not result in longer downtime (assuming existing spare capacity) because the VPS can be restarted quickly on a different hardware.
You can periodically backup your mission critical data from your datacenter to a small number of Amazon EC2 instances with Amazon Elastic Block Store (EBS) volumes, or import your virtual machine images to Amazon EC2. In the event of a disaster in your own datacenter, you can quickly launch replacement compute capacity in AWS to ensure business continuity. When the disaster is over, you can send your mission critical data back to your datacenter and terminate the Amazon EC2 instances that you no longer need. By using Amazon VPC for disaster recovery, you can have all the benefits of a disaster recovery site at a fraction of the normal cost.
As the stepping stone between Shared Hosting and a Dedicated Server, VPS Hosting provides a powerful, reliable and scalable hosting option for a myriad of different uses and applications. Whether you have a growing business, are looking to set up an online store, building a portfolio or wanting to set up unique applications, VPS Hosting is capable of supporting a number of different situations and configurations.

It can varies a lot from VPS hosts to hosts. This can be a little confusing because unfortunately many hosting providers differ in their definition of “managed hosting”, and some providers have “semi-managed hosting”. So if you’ve determined that you need a managed VPS (which is positively the way to go if you are not comfortable with running a Linux server), you must contact your potential VPS service providers for the details or look at the specific tasks that your managed provider will and will not perform.
Perhaps the best way to approach the virtual server is the idea of a virtual machine. A VM allows you to run an emulation of a computer within your computer, drawing on the resources of the physical one – disk space, RAM, CPU, etc. This tactic allows you to run an entirely separate operating system (OS) solely for the purposes of the VM, even if its type and version of OS are identical to what’s on your hardware.
koding.com has a free VM running Ubuntu. The specs are pretty good, 1 gig memory for example. They have a terminal online you can access through their website, or use SSH. The VM will go to sleep approximately 20 minutes after you log out. The reason is to discourage users from running live production code on the VM. The VM resides behind a proxy. Running web servers that only speak HTTP (port 80) should work just fine, but I think you'll get into a lot of trouble whenever you want to work directly with other ports. Many mind-like alternatives offer similar setups. Good luck!
Unmetered hosting is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use ~3 TB on 10 Mbit/s or up to ~300 TB on a 1000 Mbit/s line per month, although in practice the values will be significantly less. In a virtual private server, this will be shared bandwidth and a fair usage policy should be involved. Unlimited hosting is also commonly marketed but generally limited by acceptable usage policies and terms of service. Offers of unlimited disk space and bandwidth are always false due to cost, carrier capacities and technological boundaries.
