Selecting the right hosting service could be a tough call when not much is known about them. Small, static websites often stick to the most common form of hosting, Shared Hosting. However, the same isn’t suitable for organizations that seek to have a more secure infrastructure with greater speed and performance. This is where the notion of VPS Hosting peeps in. For websites looking to upgrade from a shared server space or those looking for a dedicated server space at affordable prices, VPS Hosting is a perfect choice. However, this would be a wild conjecture if the architecture isn’t understood properly. Hence, it’s important to have detailed knowledge of the infrastructure of VPS Server Hosting and the way it works.
What is VPS Hosting?
VPS Hosting is a popular hosting type and stands for Virtual Private Server Hosting. What happens here is that multiple websites are hosted on a single server with each having a degree of isolation as compared to the other. What this suggests is that even though several websites are hosted on a single physical server, it induces an experience of complete isolation of each server space. Thus, each virtual server space acts as an independent hosting environment with total isolation and dedicatedly allocated server resources.
Such extent of isolation is obtained by the technology of virtualization with the help of hypervisor software. The main idea behind embedding virtualization is to facilitate the functioning of every machine in a standalone environment.
VPS Hosting Architecture
As mentioned earlier, the hosting uses a dedicated software known as a hypervisor to embed the needed level of virtualization. Using the hypervisor software, a virtual machine is created which has its own set of CPU, RAM, and OS. What differentiates VPS Server Hosting from the others, specifically Shared Hosting is the fact that every user has total root access, thanks to the creation of the virtual environment. There are two different kinds of hypervisor:
- Native
- Hosted
Native hypervisors are so designed that they can directly control the hardware of the server without actually requiring an operating system on the physical machine. On the contrary, the hosted hypervisors need an OS to be installed on the physical machine to exercise its functionality. Apart from these, there are hybrid hypervisors that have a blend of both native and hosted hypervisors and perform the function of both.
How Does This Work?
- No matter what’s the type of hypervisor, all of the virtual machines are guided by them.
- Acting as the layer of virtualization, the software does the job of extracting resources from the actual physical server.
- Then, a virtual replica of the resources are created and further shared by a host of users using the server space
- Every virtual machine has its own operating system
This way, multiple websites can function on the same server without having any idea about others using the same space.
Final Word
There are multiple types of websites that require a dedicated virtual server space without shelling out a lot of money – VPS Hosting is the best fit for them. The isolated nature of the VPS architecture ensures the performance and security similar to a Dedicated Server while being as affordable as a Shared Hosting plan. However, it is crucial that you assess the offerings of the VPS Hosting India providers, match them to your specific requirements and then make the purchase of the best VPS Hosting plan.
