The current trend in Linux web server OS distributions is for extremely lightweight installation requirements and integration with containers for elastic scaling of big data applications. Rancher and CoreOS both work with Docker and Kubernetes as well as other cloud orchestration platforms like OpenStack, CloudStack, CloudFoundry, OpenShift, Mesosphere, etc. Lightweight OS installations increase the number of virtual machines that can be created on data center hardware, leading to greater efficiency in production environments.
Expert Overview
Partitioning a single server to appear as multiple servers has been increasingly common on microcomputers since the launch of VMware ESX Server in 2001. The physical server typically runs a hypervisor which is tasked with creating, releasing, and managing the resources of "guest" operating systems, or virtual machines. These guest operating systems are allocated a share of resources of the physical server, typically in a manner in which the guest is not aware of any other physical resources save for those allocated to it by the hypervisor. As a VPS runs its own copy of its operating system, customers have superuser-level access to that operating system instance, and can install almost any software that runs on the OS; however, due to the number of virtualization clients typically running on a single machine, a VPS generally has limited processor time, RAM, and disk space.[2]

If you are just starting your website and don’t receive very much traffic, then shared hosting is the ideal solution. However, if your website’s audience is consistently growing, you’ll want to consider upgrading. You don’t want to run the risk of your website running slowly or, even worse, your server crashing because it can’t handle the traffic. If you anticipate an increase in visitors, do yourself a favor and switch to VPS.

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.
Expert Overview
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.
First of all, root access offers independence from the hosting provider in terms of software. While the hosting provider still manages the server’s hardware, a choice of software is on a user. It’s you, not your hosting provider, who decides when it is the right time to upgrade, for example, cPanel or MariaDB. We cannot say that this freedom is absolute, though, compared to the dedicated hosting plan. If a bare-metal server has hosted hypervisor installed, its OS must be compatible with a guest OS. For instance, if a physical machine runs Linux, it’s impossible to install Windows as a guest OS. A native hypervisor is compatible with any OS. Apart from that limitation (and apart from illegal activities, of course), VPS users can install whatever software they want.

Now open a file manager - I use WinSCP but you can also use Webmin > Others > File Manager. Browse to the folder /home/[your domain]/public_html. It's probably empty. Download the latest version of WordPress from the download page to your PC and then upload it to the public_html folder (File > Upload to current directory) and unzip it (right click > Extract). A folder called "WordPress" should have been created. Open this folder, select all the contents (there's a "Select All" button at the top) and cut and paste them up one level to the public_html folder.


Shared hosting is not meant for websites that use large amounts of RAM. As your website grows and you add more and more content, you will start to see a decrease in your website’s load times. As soon as this happens, it’s an indication that you are maxing out your limits. Upgrading to a VPS will enable you to scale your website without having to worry about slow load times.

One of the most popular recent innovations in cloud hosting plans is the use of operating system snapshots to install full server stack software including popular CMS code and web development frameworks. For example, instead of buying a bare-metal VPS plan and installing all aspects of the OS, Apache software, programming language extensions for the web server, database frameworks, etc. individually or via the command line, system administrators can simply choose a particular stack snapshot and deploy LAMP with the latest Drupal, Redis, Varnish, Zend, Acquia Cloud, & Apache Solr versions all pre-configured under PHP 7 settings. Entire production server portraits can be captured using this method and used for backup/restore, clone site replication, elastic scaling, load balancing with multiple website copies, etc. Snapshots work with Docker containers and Kubernetes as well as VPS plans under KVM, Xen, Virtuozzo, SolusVM, OpenVZ, VMware, etc. virtualization.
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.

It’s very easy to recommend a company like Liquid Web — quality is of the highest standards, and you have plenty of room to grow. Throw that outstanding support in the bundle, together with the practically limitless customization options, and you get an irresistible VPS platform. Price is the only obvious dent to this otherwise superb hosting deal, so if you are on a tight budget, you might want to consider another option.
Dedicated: True to its name, a dedicated server is entirely yours to utilize. This is usually an option for those with a high volume of traffic or those who choose to customise their website in a specific way. However, it’s an expensive choice that might not be right for you if you’re just starting out or if your requirements aren’t too advanced. VPS offers you the same luxury of privacy and dedicated resources with a small space to rent. It offers you one piece of the whole server which is exclusively yours.

Some systems administrators will also install Nginx (or Lightspeed / Lighttpd on BSD) as alternative server frameworks to Apache using VPS plans. For example, Nginx, Varnish Cache, & WordPress can be installed on VPS hosting plans to support up to 2x the simultaneous user traffic and pageload speeds for high traffic websites when compared to the most common Apache servers. Hadoop, Tomcat, VPN, & email servers can also be run on VPS plans. Cloud VPS platforms support web and mobile applications at scale by replicating under elastic cloud architecture and can speed up DevOps deployments using snapshots like Bitnami.

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!

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.

Similarly, in a real dedicated server, you will pay for the entire server that is not shared with anyone else. You will get complete control over all services. Unfortunately, it is also the most expensive hosting option and needs some technical expertise to manage. It is commonly used by those who have websites with specific scenarios, most commonly extremely high traffic and tight security requirements.
Essentially, here’s the criteria I would use to judge things – if your site is made up of primarily static, HTML-based content, then you probably don’t need a VPS package.  However, if you have a large amount of files stored, multiple sites, dynamic content, and the possibility of major traffic from time to time, then you might consider upgrading to a VPS. It’s a powerful package that allows you to do more than you could with a shared hosting plan, but requires less investment than a dedicated server.
The hypervisor provides each guest machine (each website using the VPS) with a virtual operating system and takes care of managing and executing guest operating systems. This process makes the most effective use of computer resources such as network bandwidth, memory space and processor cycles. For this reason, a hypervisor also goes by the name of a virtual machine monitor (VMM).

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.
One of the biggest pitfalls of VPS hosting is having to manage your entire server environment by yourself. If your virtual server is not configured and maintained well, you may face serious security risks and performance loss. Managed VPS hosting services have appeared on the market as a viable solution to this problem. You can think of it as an enhanced alternative of VPS hosting, that comes with full technical support.
Your websites could vanish without warning, even at a large reputable host. It has happened to me more than once. Common causes are denial of service attacks, your site being hacked, the host going out of business, power or network failure, an expired credit card or simple human error. Your hosting provider may be swamped with calls and unresponsive when this happens. If you have a recent off-site backup and control of your domain names you can recover everything within a couple of hours - if not, recovery may be lengthy or impossible. Backups are important!

Memcached with CMS websites than the system resources provided on shared Linux plans will permit. Content Delivery Networks or CDNs cache copies of a website's files in data centers by geo-location and use DNS routing to select the version closest to the web browser or user request origin. CDN services can reduce VPS website response times considerably and reduce web traffic strain on the hardware. The main advantage of VPS hosting plans is that they provide the isolation and system resources required for advanced web server stack customizations that enable better website caching for high performance web & mobile applications at scale.

Every plan has some appealing configuration options. In particular, along with support for the usual Linux variants – CentOS, Ubuntu, Fedora, Debian – you can choose Windows Server 2008, 2012 or 2016 for only a $5 a month premium. That's very good value, and if you're more familiar with Windows than Linux, it could save you from lots of management hassles later on.
