Sometimes you need more power than an entry-level web hosting service can provide. If you're looking to take your business online and want to build your website on a server that offers more power, stability, and flexibility than shared hosting, but you don't want to pay the higher cost of dedicated hosting, VPS, or virtual private server hosting, may be the perfect middle-of-the-road service tier for your business.
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.[3]
InMotion Hosting offers 24x7x365 support with all VPS Hosting plans. We take pride in providing the best customer support on the market, giving you access to our team of experts via telephone, email, chat or Knowledge Center. We also provide Managed Hosting for a nominal cost, providing you with a dedicated system administrator to help with any technical difficulties you may encounter while setting up or maintaining your Virtual Private Server.
Virtual private servers connect shared Web hosting services and dedicated hosting services by filling the gap between them. Because virtual dedicated servers can have their own copy of the operating system, VPS provides the user with super-user privileges in the operating system. VPS enables the user to install any kind of software that is capable of running on that operating system.
We regularly examine customer bandwidth and disk space utilization data in a series of statistical analyses and use the results to define "normal". Although these tests vary from month to month, one thing remains constant: 99.95% of our customers fall into "normal" range. If your account's bandwidth or disk space utilization causes any concern, you will receive an email asking you to reduce usage. We strive to provide at least 48 hours notice to allow customers to make adjustments before we take any corrective action.

As a result of VPS hosting's hybrid nature, its cost isn't quite as low as shared hosts' fees, but it's not nearly as high as dedicated hosts' fees. You can expect to pay between $20 per month and $100 per month, depending on the configuration. Shared web hosting, on the other hand, is extremely cheap hosting; you can often set up shop for less than $10 per month. Dedicated web hosting will typically set you back $100 per month or more.
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.
With support for Linux, Windows Server, SQL Server, Oracle, IBM, and SAP, Azure Virtual Machines gives you the flexibility of virtualization for a wide range of computing solutions—development and testing, running applications, and extending your datacenter. It’s the freedom of open-source software configured the way you need it. It’s as if it was another rack in your datacenter, giving you the power to deploy an application in seconds instead of weeks.
So that could be either a virtual machine - an operating system running inside another operating system, or a virtual private server - you rent a virtual server from a company, so you have your own internet-facing server running 24/7 relatively cheap (since it's not a real server, but one of many virtual server running on an actual server). I think he might have meant the later, since you'd have to run a snartnofe (btw I love that name) non stop to benefit from it.
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.
Although multiple VPS accounts are hosted on one physical server, we can run several different virtualized operating systems on that one server. Each of these operating systems will perform as if it was on its own dedicated server, giving you all of the benefits at a fraction of the cost. InMotion Hosting uses Parallels Virtuozzo Container to virtualize the operating system.

The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
