A VPS with Plesk provides an automatically installed and secured web server platform. With all VPS servers you get flexibility and performance at a fraction of the cost of a dedicated server. Plesk simplifies server, security, website, software installation, and customer management tasks.
Virtual Servers without a Control Panel
Access servers easily using SSH on Linux or RDP on Windows --just as you would with any dedicated server. Install software and updates on a Linux VPS using YUM to manage remote packages. On a Windows VPS, use RDP to download and install any software.
VIRTUAL PRIVATE SERVERS VS CITRIX CLOUD SERVERS
The Difference Between a Virtual Private Server and a Citrix Cloud Server
The main distinguishable difference between a Virtual Private Server "VPS" and a Citrix Cloud Server is the method in which the physical servers are virtualized.
Two types of virtualization are in use today: hardware virtualization (generally known as hypervisors) and operating system virtualization (commonly referred to as containers). Both types of virtualization are broadly deployed, and each has its inherent benefits and drawbacks.
Hardware "Hypervisor" based Virtualization (Citrix Cloud Server)
A hypervisor solution virtualizes at the hardware level, creating a duplicate of all system resources –including the operating system, CPU, memory, and configuration files – in each virtual machine. This approach results in up to 20% more overhead on the server. As a result, it reduces the number of virtual servers that can be supported by a single physical server, as well as negatively affects overall system performance.
While this may initially seem like a draw back there are actually some important benefits to you:
You have a choice of operating system, unlike containers, that is independent from the base operating system installed on the server. In other words, Windows and Linux virtual servers can co-exist on the same physical server.
You have complete control over how and when operating system updates, and all other updates, are applied to your virtual server.
In our environment, using Citrix hardware based virtualization, we can provide you with a level of real-time redundancy not available from a VPS container. For example, should a single physical server fail, your virtual server(s) can automatically migrate to a standby physical server with no downtime to your end users.
With a Citrix Cloud Server, you have access to more memory, virtual CPU's and disk space --and these configurations can be easily changed to increase or decrease resources.
We negate the concern regarding an increase in server overhead by using larger, more powerful physical servers and by tightly controlling the number of virtual servers on each physical server. These actions actually result in a platform that offers higher performance and a greater amount of redundancy than our VPS container offering.
Operating System "Container" based Virtualization (Virtual Private Servers)
With operating system virtualization, a single operating system kernel can support multiple isolated virtualized instances, instead of just one. Such instances, called containers, look and feel like a real server from the point of view of their owners.
This approach provides a common virtualization layer that allocates a single set of system resources across all containers. The result is a leaner, more efficient virtualization layer, with an overhead of less than 2%. This approach translates into higher ratios of virtual servers to physical servers, near-native server performance, and unique advantages for managing the virtual environment. These advantages include dynamic reallocation of resources and lightning-fast management operations.
Using a single standard operating system on a server also offers additional advantages, besides eliminating the inefficiencies of hardware virtualization. For example, it provides:
Performance enhancements. Because there is no need to duplicate the operating system, there is also no need to duplicate drivers, further enhancing performance. And the near-native server performance available with operating system virtualization makes containers particularly efficient at virtualizing high I/O applications, such as databases and email servers.
Scalability and elasticity. The flexible design of solutions based on operating system virtualization allows any container to seamlessly scale to the resources of the entire server; and the lean architecture ensures that nearly all of the system resources will be available for use by the containers.
Since the operating system on a container based VPS is installed only once at the physical server level, all the the diskspace allocated to your VPS is available to use. For example, if you purchase a VPS with 50GB of diskspace, the entire 50GB is available for you to use. This differs from a Hypervisor based solution in which the operating system must be installed within your allocated space.
