Virtualization is a framework or methodology of dividing the resources of a computer into multiple execution environments. Virtualization techniques create multiple isolated partitions (Virtual Machines (VM) or Virtual Private Servers (VPS)) on a single physical server. There are several kinds of virtualization techniques which provide similar features but differ in the degree of abstraction and the methods used for virtualization.
It can take hours to build a web server with support for all of the programming languages and latest web standards. Managed VPS plans bring all of the software required for programming and web development (DevOps) into a PaaS product that is available instantly. From this, there are also many differences in LAMP stack configurations between webhosts. Buying a Managed WordPress VPS hosting plan with pre-configured Nginx and Varnish Cache installation can save thousands of dollars in web development costs for small businesses.

Hostinger offers reliable VPS services that can help most small and medium businesses flourish. All server configurations are feature-packed, but if your project gets too big, it might outgrow even the most powerful solution. And while other providers might offer similar options or level of support, but in terms of price, you will struggle to find anyone better than Hostinger.
A great advantage of VPS, compared to both shared and dedicated solutions is snapshot technology support. A snapshot is a state of a system at a certain point in time. It works like game saves in your favorite computer game. If a game is not going well, you can exit and start from a checkpoint. A snapshot works the same way; if you need to go back in time, your system can be restored from a snapshot to its previous state. It is extremely useful in case of a system failure or simply if you run complex tests and wish to save your progress. Unlike a backup option that copies the whole system each time you run it, a snapshot contains only changes. This means that a snapshot takes less space than a backup and can be created/restored quicker. It does not mean that you do not need backups though. Backups are still life-savers in case of operating system failure. Don’t forget to store them externally.
All FastComet VPS hosting plans include many free features, such as application, module, and template installation and free daily/weekly backup and restore of your files, CDN, and web firewall. All of these features, combined with their high reliability and reasonable pricing is making FastComet one of the fastest growing hosting companies.
However, the automatically-generated certificate is "self-signed" which means users will get browser warning that the connection can't be trusted (because there might be a man-in-the-middle intercepting the encrypted traffic). The solution is to install a free LetsEncrypt certificate by going to Virtualmin > Server Configuration > SSL Certificate > Let's Encrypt > Request Certificate. If you've done everything correctly your web site will now load with no warnings.
To connect to the Virtualmin web interface and complete the installation, point your browser to port 10000, using https for a secure connection. For example, if the IP address of your server is 192.0.2.0, the address to visit would be https://192.0.2.0:10000. You will get a warning about an untrusted certificate, which you can ignore for now. Login with same administrator username and password you used above.
While there are more affordable VPS services out there, A2 is a worthy consideration because of its excellent support. It is a company that takes a remarkable care of non-clients goes to great extents for its trusted users. Its VPS solutions tick all boxes by offering root access, fully managed, and full unmanaged virtual servers for businesses of any size and technical acumen.

Virtualization on the OS Level provides the best performance and scalability compared to other approaches. Performance of such systems can differ only about 1-3% from standalone server. They are also much simpler to administer as all of the Virtual servers can be accessed and administered from the host. Generally, such systems are best choice for server consolidation of same OS workloads.
For managing the content of individual sites, I recommend using a well-supported Content Management System (CMS) such as WordPress or Drupal. Even very basic sites need to be updated regularly and a content management system makes this much easier, as well as giving you access to themes and plugins that add useful functions such as search forms, contact forms with spam protection, image galleries, event calendars, online shops and so on. Proprietary systems or “website builders” generally have more limited features and can be very difficult to update or move to a new host.

Now if you browse to your site you should see a "Welcome to WordPress" message and some instructions. Click "Let's Go!". The next screen asks for the database name, which you will find in Virtualmin > Edit Databases, and the username and password, which you will find in the Passwords tab by clicking the little key symbol. Click "Submit". If all is well, you can now fill in the site name, admin username and password to complete the installation and log in as an administrator.
You’re paying more, so there SHOULD be a minimum uptime guarantee and better server speed. Look for a host that offers 99.5% at a very minimum, although ideally, I’d rather go with someone who offers 99.9%. Search through some reviews as there are many who have put this to the test. For example, any of WHSR’s many web host reviews include an uptime record as one of our key tests.
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.
It's also possible to select different PHP "execution modes" for each site at Virtualmin > Server Configuration > Website Options - I recommend FPM because it's significantly faster and uses less memory. I've found that the default settings sometimes result in excessive memory usage, which can be avoided by adding the following settings to Virtualmin > Services > PHP-FPM Configuration, which limit the lifetime of processes if a site has a memory leak:
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.
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.
