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.

So that’s it, then – a VPS is for everything in between, right? Well, yes…and no. A VPS (Virtual Private Server) is a flexible solution that falls in between shared and dedicated hosting, not only in price but also in the way it functions. Like a dedicated server, a site hosted on a VPS gets its own RAM and disk space; however, like a shared server, it uses the same processing capacity (CPU) as a certain number of other sites. So, while your site’s performance isn’t reliant on shared RAM and disk space, it is dependent on a shared processor. Moreover, the distribution of processor share varies from provider to provider.  The table below shows how most hosting companies break down the differences between shared, VPS, and dedicated hosting plans:

Buying a VPS plan means that you get your very own virtual server environment. You have full control over the operating system, the extensions and apps you install, and all their settings. Each physical server will still host multiple VPS customers, but not as many as with shared hosting, and typically each VPS will be allocated a share of key resources – RAM, storage space, CPU cores – for their use alone.

In fact, most webhosts will offer the same LAMP web server stack software on their managed VPS plans as their shared hosting accounts. The main difference is the level of dedicated system resource allocation, such as RAM, CPU cores, bandwidth, or storage options. VPS plans also offer far more configuration options for web server customization with the command line than shared Linux or Windows hosting plans.

You can check your hostname under Webmin > Networking > Network Configuration > Hostname and DNS Client. Unfortunately, some hosting companies overwrite this information every time a VPS is rebooted - you may need to contact them to get it changed. Choose a fully-qualified subdomain that you own, such as "webserver.mydomain.com" or "mail.mydomain.com". Do NOT accept a generic name provided by the hosting company if you will be sending email from the server because spam filters will block it and you can't easily generate SSL certificates for it.


A2 Hosting offers two VPS options. They are both great options and very affordable. The entry level option is just $9.89 per month, and the Cloud VPS is $15. They are both great choices and will be able to meet all your needs for most entry level or mid-sized sites.

Taking into account that a VPS acts as a separate server and requires minimal server administration skills, the majority of hosting providers offer paid support for their VPS plans. Such VPS are called managed or fully managed. With a managed plan, a user still has the freedom to choose software and control their VPS, and the hosting company provides the user with server administrationsupport. In some cases, getting a managed or fully managed Linux VPS might be cheaper than getting a Windows server.


For configuring and managing the server, I recommend open-source Virtualmin rather than a licensed control panel such as cPanel or Plesk because it's full-featured, it's open source, it's the cheapest way to set up multiple sites and you retain full control of the server - you can still edit config files by hand, whereas other control panels often override them. The rest of this tutorial assumes you are using Virtualmin.
InMotion Hosting is refreshingly different. Its baseline VPS-1000HA-S plan doesn't have the most eye-catching price at $27.99 per month over two years, but it's easy to see why the company asks this much. The product has a better specification – 4GB RAM, 75GB storage, 4TB bandwidth, 3 dedicated IPs – than some high-end plans from other providers, backups and a cPanel licence are included for free, and there's a 90-day money-back guarantee.

Managed VPS plans offer a managed environment similar to our shared hosting accounts, but with increased resource availability. If you are outgrowing a shared hosting environment, but are not ready yet to make the leap to a dedicated server, you should consider a managed VPS. This plan is also a good option if you need certain customizations that are not provided with shared hosting plans, but you would still like A2 Hosting to handle configuration changes, software upgrades, and other system administration tasks.

FastComet offers multiple configurations for VPS hosting, all of which are cloud-based, include SSD storage, and are fully managed and monitored. The VPS servers are optimized for many popular applications and frameworks, including WordPress, Joomla, Drupal, and OpenCart. All VPS plans also include 24x7 support for both your infrastructure and applications – with a 10-minute response time! If you are an experienced server administrator you can also have root access to your VPS.

The most obvious and popular reason for a VPS is to run a single website, or multiple websites. However, you can use them for pretty much anything that requires access to the internet – such as a web application like Nextcloud to run your own Dropbox alternative – or to create your own virtual private network to better secure the internet connection of your PCs and mobile devices.
VPS.net offers a chargable service for tasks that are additional to ordinary support requests. Customers can also purchase a managed service package which provides peace of mind via professional server management from the host. This in turn provides customers with a comprehensive SLA which goes beyond the SLA specified on other hosting services offered by the company.

Managed VPS plans offer a "plug & play" or turnkey approach to PaaS web server stack software that makes web development more efficient. Many companies program custom web & mobile apps on managed VPS plans before transferring them to elastic cloud networks for production.  Containers and snapshots allow for the easy transfer of an entire managed VPS platform between cloud architectures or service providers.

My no. 2 tip is to set up daily off-site backups, including database contents. Human error (accidentally deleting files) is an even bigger threat than hackers and in any case it's impossible to make a VPS 100% secure or reliable so you need to be able to recover quickly. Individual WordPress sites (even on shared hosting) can easily be backed up to a free Google Drive account using UpdraftPlus.

That’s really the biggest benefit to migrating from a shared to a virtual server: Your site can grow to receive more visitors without you having to eat the higher cost and hardware responsibility of a dedicated server. VPS users are rarely first-time site owners or folks seeking a personal email server. Typically, the people using a VPS are those whose sites or apps are receiving upward of 100,000 visitors a month.
Two unique features that InMotion VPS hosting provides for free are the Resource Monitoring Dashboard which provides you with charts and graphs to monitor resource usage and allocation on your VPS partition and the Live-State Snapshots functionality, which goes beyond the (free) daily backups and allow you to restore your machine to a specific “known” working state.

This means just a few domains could pull an entire reseller website offline if transfer limits are not closely monitored on a regular basis. Many Cloud VPS plans offer a "pay as you go" approach to billing where only the actual amount of CPU resources, storage, and I/O processes are billed. Systems administrators and website publishers need to calculate expected monthly traffic rates when estimating how many system resources are required to support a website in production. "Pay as you go" approaches can be more costly than fixed ratio accounts, where the trade-off is typically a more advanced VPS platform and toolset.
Hostinger offers one of the cheapest VPS plans on the market. For only a few bucks a month, you can dip your toes into the world of VPS hosting. The most affordable plan only has 1 CPU core, 1 GB of RAM, and 20 GB of storage. However, the highest plan features 8 cores, 8 GB of RAM, and 160 GB of storage. There are eight plans in total, allowing you to choose the best one for your needs.
When you’re choosing a server, there are many things to consider – chief among them is the benefits of each. Here, we’re going to tell you why you should consider VPS for your website. If you’re feeling the need for some breathing room but can’t afford a dedicated server (where 100 per cent of the servers’ resources are dedicated to your website), VPS is the perfect compromise. However, the advantages don’t end there, and we’ll tell you why:
A virtual private server (VPS) is essentially the same thing, except for one key difference. A VPS has been partitioned so that the one server has been split into multiple “mini” virtual servers. Basically, the hosting companies use virtualization to let them make several virtual machines on one computer. Each of these servers can act independently of each other.
ScalaHosting allows you to have your own fully managed cloud VPS with a control panel and daily backups.
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.

Operating System virtualization refers primarily to Type-2 hypervisors like KVM or platforms like OpenVZ & Virtuozzo that share the Linux kernel (+ drivers) between partitions on the same web server hardware. This form of VPS is common in managed cloud plans where the web hosting company provides a custom web server stack software such as LAMP/LEMP pre-installed on a VM partition. Multiple customers can share a single dedicated or rackmount server with better security, file isolation, database, and programming language extension support than shared hosting provides, as well as having access to a higher level of web server resources when processing scripts like PHP, Python, or Node.js code. Some forms of OS virtualization will also permit Windows, Linux, & BSD to be installed on the same physical hardware.
