It works quite like shared hosting, as both of them are virtual hosting. However, shared hosting does not allow to extend or modify server settings. VPS hosting is more like a dedicated physical server on a virtual platform. You can manage and set up VPS for your requirements, as it is a separate server. Also, VPS server can be operated by a control panel that can be installed with a few clicks from the client system or the terminal command line. It means that you can even choose the same control panel as it is on shared hosting.
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!

InMotion Hosting's Virtual Private Servers are now using Solid State Drives (SSDs), a type of hard drive that uses no mechanical parts and provides substantial performance upgrades from traditional spinning drives. Solid State Drives give you faster read/write speeds, can handle more disk requests and can push through significantly more data than a standard Hard Disk Drive (HDD).

I actually going to bump this up to a little more 40 gigabytes in here as being my hard drive and it’s a will create this one my e drivers actually in this case. It’s a solid-state drive and that’s why I already configured it earlier to use as my default. Go in and say yes and create this one. Before I start the installations one thing I’m going to do in here is actually changing my amount of processes because it’s going to install Windows a lot faster if I actually give it more CPUs in here.
VPS can be a perfect solution for businesses that want many of the features of a dedicated server but don't have the resources to physically host, support and maintain the server hardware. A shared environment won't offer you the same bandwidth or Web hosting space that a VPS will be able to support and there are also many more constraints on the software you can run in a shared hosting environment. In contrast, a VPS will give you the freedom to install, delete, reboot and do all the functions as if you have your own server. You also get an increased level of security as each VPS is isolated and completely separate from other Virtual Private Servers on the same physical server. The environment is secure and protected and each VPS can be rebooted or stopped independently – even if a hacker infiltrates one VPS there is no access to the others using the same physical server.

Most VPS hosts only offer servers running Linux-based operating systems; you'll need to dig a bit to find Windows-based VPS hosting. This is important to note if you're planning on running software that requires a Microsoft-compatible environment. That said, Linux-based VPS hosting will save you a few bucks; Linux servers usually cost $10 to $20 less than Windows servers.
VPS hosting works the same as Shared Hosting, except you have additional features such as your own WHM panel. If you have any questions about the specifics of our hosting, be sure to contact our Live Sales center for more help. Contact information for the Sales team can be found at the bottom of the page. They can be contacted via phone/chat/email/Skype.

InMotion Hosting is #1 in transfers for a reason. That's because we offer all the tools, speed, and security someone may need - and more. Our AutoSSL feature, powered by cPanel and Comodo, allows you to issue SNI SSLs for each and every website you host with us. Enable auto-renewal to have peace of mind knowing your websites stay secure for your visitors. Our VPS servers are also fully compatible with Let's Encrypt, although you'll have to install and manage it independently.
The golden rule for unmanaged VPS hosting is this: If you have a problem with your unmanaged VPS Account, it is your problem. If the problem is software related, resource related, performance related, need troubleshooting or configuration of software, or need general help understanding Unix or server applications, you are on your own and should not expect help from the web host.

When you read about VPS hosting, some questions naturally arise. Let's say, if there are multiple users on the same dedicated server, running virtual private servers, will they be able to access my data? That’s a valid question to raise, but in this case, we can happily inform you that you’re safe. All VPS hosting services are safely partitioned by specific software, which guarantees top-notch protection.
Do you plan to sell products or services? If so, you'll want to invest in a web hosting service that offers Secure Sockets Layer (SSL). An SSL connection encrypts the financial information that shuttles between users' web browsers and your website, thus safeguarding the transmission of the purchasing information. Some hosting companies include a free SSL certificate when you sign up for a web hosting plan, while others charge close to $100. You can save some money by shopping around for services that offer the cheaper SSL plans.
VPS hosting contains the best elements of shared hosting and dedicated hosting services. Like shared hosting, VPS hosting puts your website on a server that also has other sites running on it, except that there are fewer sites per server. The sites share the cost of running on the server, which results in a monthly or yearly charge that's less than the relatively high price tag of dedicated hosting.
Included IP addresses are provided for free but on a need basis. ARIN rules require actual usage of an IP address so you must submit the domain name associated with any additional IP addresses. Additional IP addresses above the included IPs are available - please call our sales staff for pricing depending on number of IPs required. Limitations apply and this is no guarantee of availability.
If you register a domain with Bluehost when signing up for a hosting account, there is a domain fee that is non-refundable. This not only covers our costs, but ensures that you won't lose your domain name. Regardless of the status of your hosting service, you'll be free to manage it, transfer it after any required lock periods, or simply point it elsewhere at your convenience. You retain ownership of your domain until the end of its registration period unless you elect to extend it. 
Virtual Private Server is one of the best servers if you are looking for dedicated server functionality at a lesser price. VPS goes economical once you go for a unmanaged plan. In unmanaged plan you root login details where you can manage your server. Unlike the managed VPS, your do not bear pain of managing server optimization, server security. All such procedures are taken care by our technician. Unmanaged VPS are for those people who have sound knowledge of technical details of Linux. Once you have the technical knowledge you can manage any operating system and other details for testing or running a hosting server for your customers.
Our cloud provisioning system is able to rapidly deploy new servers after orders have been verified. The setup time for a VPS server actually varies depending on if you are using a Linux or Windows operating system. On Linux based servers you should see the VPS online within 15-30 minutes. For a Windows based server you will see the VPS online within 1-2 hours.
Getting started with a managed VPS hosting is easy with Bluehost as your VPS hosting provider. Simply choose from our Standard, Enhanced, or Ultimate VPS hosting packages based on the amount of resources your website needs and follow the sign up instructions. Once you have an account, you can easily upgrade to more resources from within your customer dashboard.

If you host it in a VPS environment, your site won't share resources with neighboring sites, the way it would with shared hosting. In fact, your site lives in a partitioned server area that has its own operating system, storage, RAM, and monthly data transfer limits, so you can expect smoother, more stable site performance. The sites with which you share your server are far less likely to affect your site—or even take it down altogether—than they would be on a shared site. Knowing how VPS setups operate is just the first step, however. You still need to familiarize yourself with the essential features needed for building a rock-solid, VPS-hosted website.
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.

Mirror and share a deep copy of your in and outbound virtual network traffic. Take advantage of aggregation, packet collection and load balancing solutions by streaming traffic to a destination IP endpoint or an internal load balancer in the same Virtual Network, peered Virtual Network or Network Virtual Appliance that you can deploy from a growing list of Security, Network and Application performance management partners.
Traffic Handling Users of the server may be hampered by an excessive number of requests from a webpage or application. Your website may become very slow or even temporarily stop. Because this system has its own piece of server capacity that other users can not access, you will not be hampered by other websites or applications. The performance of your website will naturally become a little better and more reliable. The question of being hampered by other websites or applications do not arise at all.
Get the control panel you prefer by selecting it at order time. Either is available - it's strictly a matter of personal preference. Many people opt for cPanel, because of its popularity - and we can't fault them for that. However, it’s your VPS – so you’re in control - you can have other control panels and software installed instead - it's totally up to you (but faster setup times if you pick cPanel or DirectAdmin).
All the features I've detailed to this point are valuable to the web hosting experience, but none matches the critical importance of site uptime. If your site is down, clients or customers will be unable to find you or access your products or services. It doesn't matter how great the features are, or how good it looks; if your site is down, it might as well not exist.
A managed VPS setup will help you with upgrades and installations, as well as server monitoring and cyber security. With cyber security threats constantly evolving, this could save you hours of your week that would otherwise be spent searching for and installing patches and upgrades. Cyber security expertise is invaluable in today’s market, with users expecting their personal data to be held securely.
Shared hosting packages are aimed for small projects, such as personal blogs and similar sites. Resource intensive or high-traffic projects might encounter issues while using a shared hosting service. Shared hosting is incredibly beginner friendly and fully managed, which means that our customer support team will be able to help out with most issues that might occur with your project.

Power, robustness, and flexibility guaranteed!
A virtual private server (VPS), also called a virtual dedicated server (VDS), is a virtual server that appears to the user as a dedicated server, but that is actually installed on a computer serving multiple websites. A single computer can have several VPSs, each one with its own operating system (OS) that runs the hosting software for a particular user.
