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.



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:

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.

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.
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.

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.
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.
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.[3]
By default, email reports of any system problems will be sent to user "root". You can read them by going to Webmin > System > Users and Groups > root and clicking the "Read Email" button. It's usually more convenient to forward them to an external email address. You can configure this by going to Webmin > Servers > Postfix Mail Server > Mail Aliases, selecting Create a new alias and setting Address to "root" and your email address in "Alias to", "Email address".
It is rumored that Linux servers are more secure than Windows. Well, it depends on who implements security enhancements on a VPS. There is plenty of information on the Internet about securing both Windows and Linux servers. One of the Windows server weak spots, Active Directory, can be protected using several simple steps; Linux distros have SELinux control system and other security tools. It is possible to maintain a decent level of security on any platform; however, it requires server administration skills.

Expert Overview
Unlike VPS, a dedicated server lets you choose the equipment, including the RAM, hard drive, and processor used in the server. As 100 percent of the server’s resources are allocated to your site, it costs more than VPS hosting. However, dedicated server hosting is the best hosting option for you if you don’t want to share resources with other websites by any means.

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).
Yes, VPS is a powerful and versatile type of hosting that many companies will find meets their needs. If you’re already hosting in a different type of environment, you may be wondering whether it’s worthwhile to migrate to VPS. This is an important discussion to have with each prospective hosting provider in order to understand how they handle migrations, what would be required from you, how long it might take, and any costs associated.
Similarly, in the case of VPS, there are several users that are using the same server but they are isolated from each other. It means that no one will be affected by how much resources another is using. You will get the speed and security that you need without compromise. It is almost a perfect scenario because you will get the benefits of a private server with shared cost of services.
The moment you plan on running an online store is the moment you should upgrade your hosting plan. Why? Because with VPS, you have a secure and dedicated virtual server where you are more likely to pass a PCI compliance test. The Payment Card Industry Data Security Standard was established by major credit card brands to protect against cardholder data theft.
Providers like Bluehost and iPage offer instant deployment, so you can quickly get on to business. The InMotion Hosting team offers Launch Assist — two hours of assistance from experienced SysAdmins — to customers who sign up for 12 months or longer. Our team tested all the top VPS hosts and found the signup times to take around six or seven minutes, so getting started is — virtually — a snap.
