Virtual Private Server, i.e., VPS, is a website hosting solution that provides a combination of benefits. One physical server is divided into multiple virtual servers, creating multiple mini-dedicated server environments.
VPS hosting offers the cost-efficiency of shared hosting and the reliability of dedicated servers, allowing users to have the best of both worlds. This is possible because of virtualisation and hypervisor technology in VPS hosting.
In this blog, we explore hypervisor’s meaning, its technology and how it works with your VPS hosting package.
What Is Hypervisor Technology?
Hypervisor technology is the core software layer that enables virtualisation. Also known as a virtual machine monitor, the hypervisor allows a physical host, a physical server in this case, to run multiple virtual machines, i.e., virtual servers. This is possible because the hypervisor abstracts hardware resources and allocates them to each virtual machine.
Hypervisors are vital to the functioning of a virtual private server hosting environment. Their ability to partition the server and allocate resources defines a hypervisor. Let us understand the hypervisor technology in VPS and its functionality!
Defining A Hypervisor’s Functionality
● Resource Allocation
As mentioned above, the hypervisor divides a server into multiple virtual parts, each housing a website. The hypervisor technology in VPS ensures adequate resource allocation to each part.
Resource allocation is the hypervisor’s ability to efficiently distribute the physical server’s resources among the multiple virtual servers. The hypervisor dynamically adjusts the allocation of CPU, RAM, bandwidth and storage, ensuring fair distribution and even availability.
● Virtual Server Management
Hypervisors simplify server management when it comes to VPS hosting. It enables the creation and configuration of virtual servers by providing tools to create, modify, adjust, and monitor virtual servers.
The hypervisor technology in VPS allows administrators to seamlessly deploy a virtual server, scale resources up or down on demand and migrate the server data with minimal downtime.
● Installing Oeprating Systems
Unlike shared hosting, where all the co-tenants use a single operating system, VPS hosting offers flexibility and choice regarding OS. Thanks to virtualisation and hypervisor technology, all users can opt for an OS of their choice.
The hypervisor enables the server to install multiple OSs for multiple tenants. This allows it to run Windows, Linux and other OSs simultaneously, catering to diverse application needs without requiring additional hardware or migration.
● Isolation and Security
One of the primary benefits of the hypervisor technology in VPS is that it offers physical isolation from other users. Its ability to isolate and offer privacy, security and stability is unparalleled.
If one virtual server is compromised or breached, it does not affect the other users. Additionally, the failure or overload of one virtual server does not impact another’s performance, offering stability.
● Performance Optimisation
Hypervisor technology is designed to optimise the performance of the host and the virtual servers. It can balance the workload across available resources efficiently. It can also minimise resource consumption and contention between servers.
Virtualisation also allows load balancing and live migration to ensure optimal uptime and performance.
Conclusion
Understanding hypervisors and their functionality is important before you purchase a VPS hosting plan. Virtualisation and hypervisor technology are the cornerstones of VPS hosting. Without the virtual machine creation and management, you only get a shared hosting environment.
Thanks to hypervisor technology in VPS, this hosting solution offers standout features like flexibility, privacy and reliability, making it a significant player in the web hosting industry.
