What these services provide you with is essentially a user account, except it is on a machine hosted on fast networks at a professional data center managed by professional system administrators. Typically, you share your user account with other users on the same machine and are given a set amount of resources (bandwidth, disk space, CPU minutes) that you are permitted to use. Providers can offer shells (SSH access), website hosting, e-mail hosting, DNS hosting, and more.

Note that I have included tests from some reputable DNS blacklists - these can make a big difference to server load. Barracuda requires you to register your IP address. Note also that I have enabled memcached to avoid a problem with "unable to get exclusive lock" errors in the mail log. Memcache is also useful for caching plugins like W3 Total Cache in WordPress. You can install it with a simple APT command:
A virtual private server (VPS) is ideal for those seeking scalable, reliable hosting resources at a reasonable monthly price. Recently, our team signed up for, tested, and reviewed every major VPS hosting service to find the best combination of uptime, pricing, support, and scalability of all the available VPS hosts. Below are our top recommendations for the best VPS hosting providers:

I recommend using Cloudflare for your DNS settings rather than the nameservers provided by your domain registrar or a nameserver set up on your own VPS using BIND, because you are supposed to have at least two nameservers (in different locations) for redundancy and because you can quickly switch on Cloudflare's content delivery network of proxy servers if you get hit with a load spike or a DoS attack.
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.
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.

• Fully Managed VPS Tech Support
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 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.
With dedicated hosting, you rent an entire physical server for your business. If you have a high-traffic website dedicated hosting can be the best solution for you, as dedicated servers are fast, flexible, and fully customizable. However, the service definitely comes with a price tag as well, so they are not worth for everyone, especially if you have a small or medium website.
Ubuntu is one of the most popular desktop Linux distributions which also has a web server variant as well as the Kubuntu package. Overall, Ubuntu, Debian, and Red Hat Enterprise Linux (RHEL) are commonly found in web hosting and private cloud data centers in use as web servers, with Fedora and openSUSE more popular among independent web developers and PHP/Python programmers.

Types of VPN offered: OpenVPN, Wireguard, StealthVPN, OpenWeb, PPTP, L2TP/IPSec, SSTP, AnyConnect
• Solid State Drives for All VPS Hosting
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.
You can also create "Sub-servers" and "Alias" servers. Alias servers are useful if for example you have both a ".com" and a ".co.uk" domain - website visitors and mail users can use either domain and will see the same website or reach the same mailbox. Sub-servers are useful if one administrator is managing several different sites - if they all have the same owner then there's no need to log in and out to move between them.

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.
