There are numerous open source Linux virtualization platforms based on KVM, while Microsoft has Hyper-V with Windows cloud servers, Citrix maintains the Xen server framework, and VMware has a number of different hypervisor frameworks such as ESXi. Hypervisors permit the managing of multiple web servers independently on shared hardware each with isolated databases, file storage, and I/O request processing.
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.
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.

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.

Quick review: AltusHost is a well-known premium hosting provider based in Netherlands. The company provides rock-solid customer support and offer three different server locations in Europe (Bulgaria, Netherlands, and Sweeden). We think AltusHost may be the right call for small businesses and individual bloggers who want a reliable EU-based hosting solution.


It all starts with a dedicated server (a.k.a. a bare-metal server). Instead of using it as a dedicated server or dividing it into hundreds of shared accounts, a server owner decides to turn it into dozens of smaller servers (here comes a difference between shared and VPS hosting - with shared hosting you get an ‘account’, while with VPS you get a ‘server’). In order to divide a bare-metal server into several virtual machines (i.e. in order to virtualize a server), we need to install software called hypervisor.
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:
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.
Expert Overview:

The licensing differences between Microsoft and open source solutions extend to the other platforms & extensions used on web servers for cloud software development, web publishing, ecommerce, and data center management. The choice of proprietary vs. open source licensing will normally be a major factordetermining the use of Windows vs. Linux in VPS hosting. Open Source platforms offer free software and development tools without the cost of the Microsoft ecosystem, but businesses and publishers will still need to invest in experienced web development and programming teams to build custom solutions.



RAID storage differentials are largely based on the number of disk drives and synchronized duplicate copies of data files available. SSD storage with Docker containers, Kubernetes elastic cloud networks, and isolated VPS/VM partitions are considered fundamentals in cloud data center architecture today. Many shared Linux webhosts make extensive use of SSD storage in VRAM configurations.
When you create a website, you have to pay a company to host it on their server. This is a powerful computer that allows anyone on the internet to connect and access your site. The lowest level of server is a shared hosting plan where hundreds of websites (and all their data) are stored on one server with all of the server’s resources up for grabs depending on who needs them.


Expert Overview

For security reasons, the first thing you should do after starting the server for the first time is login at the console using the administrator username and password (as configured above or given to you by the hosting company) and install the latest operating system patches. On Ubuntu and other Debian-based systems you can do this with the following commands:
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.

To sum up, a Windows server is more friendly to beginners but is less flexible and more expensive. A Linux server is cheaper and offers more freedom though it requires special skills and does not have a developed support system. Still, the most important question you need to ask yourself is whether your main goal requires Windows or Linux. If you need a Linux server for your needs but do not have required skills to manage it, you can sign up for a managed VPS.
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.


While there are many similarities between having a VPS Hosting plan and a Shared Hosting plan, you will notice that there are some additional features and functions you are provided with. For example, InMotion Hosting provides you with the WebHost Manager (WHM) which allows you to access Server Configuration, Account Information, Security, Account Functions, SSL/TLS, cPanel, and more. Keep in mind that your VPS cPanel usually doesn’t include Softaculous like most Shared Hosting cPanel implementations. If you aren’t comfortable manually installing your software applications such as WordPress, you can usually purchase a Softaculous license for easy software installs.

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.
The "slashdot" effect is the main problem which will lead to VPS hosted website crashes more than any other. For example, if a VPS plan has an allocation of 2 GB of RAM and 2 CPU cores with a maximum support for around 200 simultaneous users of a complex Drupal or WordPress site, a popular social media link may temporarily increase traffic to a website 10x or 100x. In these cases, the VPS will crash... unless the overflow can be managed by burstable RAM or elastic cloud scalability. In elastic frameworks, the network monitoring software simply launches a new VPS instance with a cloned & synchronized version of the website files that can manage the additional user demand. When the traffic spikes decrease, elastic server networks can automatically scale down VPS instances to conserve resource utilization in production.
Managed VPS plans offer a managed environment similar to our shared hosting accounts, but with increased resource availability. If you are outgrowing a shared hosting environment, but are not ready yet to make the leap to a dedicated server, you should consider a managed VPS. This plan is also a good option if you need certain customizations that are not provided with shared hosting plans, but you would still like A2 Hosting to handle configuration changes, software upgrades, and other system administration tasks.
You will need to change the Domain Name System (DNS) settings to point to each new site that is added to your VPS - this is how the human-readable website addresses and email addresses get translated into machine-readable IP addresses. Each DNS change can take 24 hours or more to propagate around the worldwide DNS network. If you're impatient you can access the site in "preview" mode at Virtualmin > Services > Preview Website or you can access the site directly by IP address (by entering an address like https://192.0.2.0 in your web browser) or you can modify the "hosts" file on your computer (on Windows this is usually located at C:\Windows\System32\drivers\etc\hosts, on a Mac it's at /etc/hosts and you need to be an administrator in both cases).
Some virtualization platforms, primarily "bare metal" hypervisors, do not permit the realtime allocation or alteration of system resources to VPS partitions. Managed VPS plans including cPanel offer the AWStats service for viewing metered bandwidth on web traffic by month & day. Google Webmaster Tools is another good resource for monitoring and calculating the average traffic usage for a website by geo-location, time of day, weekend use, holiday rates, etc.

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:
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.
With a standard shared hosting plan, you’re at the whims of other webmasters who share the same server. Some companies put hundreds of websites on the same physical server. If one of those sites experiences significant growth or gets a sudden influx of traffic, your site’s performance will suffer. There are only so many resources to go around. When one site needs more resources, it’ll hog them and cause issues with the other sites.
The answer to this question is a definitive “maybe.” Since you’re looking at this site, you might be a Web designer who has a few sites, an online portfolio, and a couple of long-standing clients whose sites you manage. Is a VPS for you? Well, you’ve most likely outgrown a shared platform, and as a professional, it won’t do to have your site run poorly because another site that you share a server with is using more than its fair share of resources. A dedicated server could be overkill – if you don’t need all the resources on a consistent basis, you may not be able to justify the expense.

• Daily & Weekly Backup of VPS Data
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.
