VPS can be a perfect solution for businesses that want many of the features of a dedicated server but don't have the resources to physically host, support and maintain the server hardware. A shared environment won't offer you the same bandwidth or Web hosting space that a VPS will be able to support and there are also many more constraints on the software you can run in a shared hosting environment. In contrast, a VPS will give you the freedom to install, delete, reboot and do all the functions as if you have your own server. You also get an increased level of security as each VPS is isolated and completely separate from other Virtual Private Servers on the same physical server. The environment is secure and protected and each VPS can be rebooted or stopped independently – even if a hacker infiltrates one VPS there is no access to the others using the same physical server.

The most common type of VPS is a web host. Many web hosting companies offer VPS hosting solutions as an alternative to shared hosting and dedicated hosting. A VPS sits in between the two options, usually in both performance and price. Like a shared host, a VPS may share the resources of a physical machine with other hosting accounts. However, a VPS is custom-configureable like a dedicated hosting solution it is isolated ("private") from other accounts.

Not everybody is a server administrator, which is why our managed VPS servers and cPanel make server maintenance easier than ever. cPanel provides automatic updates for a myriad of deployable software, meaning you don't have to constantly monitor updates for your website(s). If you want to update your server software manually for integration and compatibility reasons, that capability is provided for you as well within the Server Configuration section of cPanel.
VPS hosting is essentially a virtual slice of a server which you can scale to your own needs with your own dedicated resources. At Hostek, we never over-sell server capacity, in fact we operate in a highly available server environment and, on top of that, we’ll transfer you to another available server space in the event that your host server goes down.
If you are not already familiar with Linux system administration, you will need to devote a great deal of time to familiarizing yourself with all of the applications you're using and the CentOS operating system - you could pay someone else to set up your VPS for you, but that wouldn't help down the road when you need to update software and resolve administrative issues... (if you're not sure, go with a managed service)
Perhaps the best way to approach the virtual server is the idea of a virtual machine. A VM allows you to run an emulation of a computer within your computer, drawing on the resources of the physical one –  disk space, RAM, CPU, etc. This tactic allows you to run an entirely separate operating system (OS) solely for the purposes of the VM, even if its type and version of OS are identical to what’s on your hardware.
A virtual private server (VPS), also called a virtual dedicated server (VDS), is a virtual server that appears to the user as a dedicated server, but that is actually installed on a computer serving multiple websites. A single computer can have several VPSs, each one with its own operating system (OS) that runs the hosting software for a particular user.

OpenVZ virtualization is an OS level container-based virtualization, and it has resources that are divided between users on a physical server. Each container acts like a stand-alone virtual server and can be accessed with a root (SSH) connection. As a separate server container can be rebooted separately, it also has a dedicated IP address, shared RAM, individual processes, files, applications, system libraries and configuration files. On OpenVZ, the kernel cannot be modified. It has its stable version and modules cannot be added. The good thing regarding this virtualization is a faster performance, and a lower need of resources.


Both single-machine and cloud-based VPSes are managed using a software program called a hypervisor. The machine that runs the hypervisor is called the host machine and the individual virtual private servers are called guest machines or guest instances. The hypervisor can start and stop the virtual machines and allocates system resources, such as CPU, memory, and disk storage to each VPS.
A Cloud VPS is an emulation of a computer, also known as a virtual private server, that lives within a parent server and shares resources with other virtual servers. A Dedicated Server is a stand-alone, physical server that does not share resources. As with fixed resources, scarcity can lead to less than optimal performance for the resource-intensive application, which is why Dedicated Servers often outperform VPS instances.
VPS users still have access to the same resources and features as they would have otherwise, and they still have the freedom to install any application and make changes to those applications. Since you are not actually sharing any hardware, you will not have to be concerned about the physical server maintenance and security. The hosting company will need to worry about this.

The primary disadvantage to using a VPS is its lack of performance. The organization that provides the VPS will typically throttle the server's performance in an effort to maximize the number of VPSs that the physical server is able to accommodate. In the unlikely event that the VPS's performance is not throttled, it then becomes possible for an adjacent VPS to consume excessive resources, to the point of impacting the VPS's performance.

You're an experienced developer who wants full control over your environment. We're giving it to you! You get root access so you're able to access and edit all of your server's files! You get to choose your Linux OS and can even re-load your server with a new operating system on demand! You also get boot, shutdown and reboot control. Now we're talking about serious hosting!

One of the tools included with your Managed VPS within cPanel is Softaculous Free. Softaculous is another reason why these plans are easy to use. With Softaculous, you can setup software ranging from blogs to forums to CMS solutions all with a single click of your mouse. As the Premium Hosting partner for PrestaShop, you can also setup this popular eCommerce software with 1-click as well.
To break things down a bit, cloud VPS (Virtual Private Server) hosting is when a web hosting provider takes one massive server and partitions it up so that it can have several servers on it, each of which can run its own operating system and can be re-booted independently.  Sounds simple enough.  So what is the difference between managed VPS and unmanaged VPS?
f. In a few minutes, the Instance State column on your instance will change to "running" and a Public IP address will be shown. You can refresh these Instance State columns by pressing the refresh button on the right just above the table. Copy the Public IP address of your AWS instance, so you can use it when we connect to the instance using SSH in Step 4.
