Most applications running on a server can easily share a machine with others, if they could be isolated and secured. Further, in most situations, different operating systems are not required on the same server, merely multiple instances of a single Operating System. OS Virtualization systems have been designed to provide the required isolation and security to run multiple applications or copies of the same (or similar i.e different Linuxes) OS on the same server. OpenVZ, Linux-VServer are examples of OS virtualization.
Other powerful features included in InterServer VPS hosting plans are high performance SSD storage, easy to use VPS control panel, instant provisioning, and 99.9% uptime guarantee. They also provide 100s of free scripts to make it easy to install the most popular applications on your VPS server.
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 web hosting environments work in the same way as a virtualized operating system in the sense that one server will run numerous, one of a kind virtualized OS’s on a single server -since each virtualized system behaves as though it is a dedicated server. Virtualization is possible through a hypervisor. A hypervisor is computer hardware, software or firmware that creates and runs virtual machines (VM) by separating the underlying physical hardware from a computer’s operating system and applications. The computer system on which the hypervisor runs is known as a host machine, and each VM is called a guest machine.
Most services on a VPS have to be publicly visible all the time and unnecessary services should be disabled anyway, so a firewall is not as useful as you might think. Nevertheless, a firewall helps to protect against some types of denial of service (DoS) attack and is needed by fail2ban if you use that to block brute force attacks. Firewalld is set up and enabled by default by Webmin and needs no further configuration - it works for IPv6 as well as IPv4.
If you want to control your server from the deepest level possible, you’re going to need to go with a VPS plan that offers root access. Root access allows you to edit all of the files on your virtual server. This includes system-critical files. Having this access can be beneficial if you’re looking to install programs or implement complex coding. However, it’s very easy to ruin your site when you have full root access.
There are a few downsides to shared hosting, though, mostly because you’re sharing. For instance, if someone else on your shared server has a huge spike in traffic, that could affect your website’s performance. However, if you’re just getting your website off the ground and don’t have huge traffic volume, shared hosting is a great way to get online!
Whatever your VPS hosting needs, you can create a configuration for it at InterServer. InterServer is one of the few hosting companies that offer both Linux (multiple flavors) and Windows VPS servers. They also offer the option of several different virtualization platforms such as OpenVZ, KVM, or cloud. Depending on your configuration, you can choose between a fully managed and a full control (for you) server.
Now go to Virtualmin > Server Configuration > Manage SSL Certificate and select the Let's Encrypt tab. Select Domain names listed here and insert the server's hostname. Click Request Certificate and your free certificate should be installed. Four new buttons will appear to allow you to copy this certificate to Webmin, Usermin, Postfix and Dovecot - click each of them in turn. Your server now has free certificates installed, and they will update automatically every 2 months.
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.
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.
Keep firmly in your mind the sort of assets that you require to serve your site(s) when seeking a host. Cost in a VPS is important, but not as key as you might think. VPS resource availability is scalable, so the cost that needs to be looked at is comparable cost from one host to the next. Also – as cPanel revised their pricing model recently, web hosting companies across the board will have to pass those costs on to users sooner or later. You will need to consider the cost of control panel when selecting a VPS plan. Companies like ScalaHosting has developed their own control panel to mitigate this issue – so their users would have little issues with the price hike.
VPS.net does not make any claims about uptime, but as its services are based on cloud hosting, this is unsurprising – the whole idea of the cloud is to provide better reliability anyway. The website advertises its cloud hosting as being based on ‘self-healing hardware’. Should the server your site is held on go down or fail for some reason, it will automatically transfer to another server within seconds, meaning that downtime should be practically nil in real times.
Be careful, though – there are some common traps many people fall into. Firstly, the promotional prices are only on offer for a month, after which you’re paying between $49.99 and $299.99/month on any of its five plans. Secondly, the 30 day, money-back guarantee is only valid for those who subscribe for a year or longer. Everyone else only has 48 hours to claim a refund.
