History Revolving Around The World Of VPS
Nowadays, it is rather hard to operate online without VPS hosting, but have you ever wondered where it came from? Described as one of the most promising innovation in the history of web hosting, VPS allows one host device to work as multiple computers. You just need a single physical server alongside virtualization, and the result will just be amazing. However, it’s not that old new to be honest. It was in the 1960s, when IBM detailed the concepts of virtualization for lowering costs and even taking care of tasks simply.
Started all with VM:
The history of VPS started most importantly with virtual machine or VM. It is mainly emulation of the current computer system. These virtual machines are solely based on computer architectures and can offer functionality of physical computer. These implementations might involve specialized software, hardware or even a proper combination.
To catch up with multiple functionalities, VM comprises of multiple kinds. You have system virtual machines or process virtual machines, designed for executing multiple computer programs.
Next stop in the list:
After the wonderful success of VM, you have UML in the platform of web hosting delight. Also known as user-mode Linux, this design used to enable multiple forms of virtual kernel based OSs, for running applications within standard Linux system. This approach was a fascinating one and provides the users with opportunity to run multiple virtual Linux based machines on single hardware. This might offer some isolation, without affecting the stability of configuration of the host environment.
Through UML, multiple things start to work promisingly. It provides the users to run network service, straight from the UML environment and remain sequestered from major Linux system, where the UML runs. It was a perfect turning point for administrators as well, who got the liberty to use UML for setting up honeypots.
Changing to Xen or KVM:
The Xen project took place in 2004, where there was no sign of open source virtualization. This platform comprises of some impressive scalability advantages to use Jail or container. Xen came out as the Type I Hypervisor, which can sits on single layer above the current bare metal. It works more like a stripped down operating system, and its function was stated as “pass through” for connecting directly to PCI devices.
On the other hand, KVM was considered as a Type II Hypervisor. T is primarily one layer above OS. It means you need one bare metal machine, then install OS and after then get the chance to install KVM. In case of Linux, KVM was installed in Kernel formation, which turns bare metal machine into possible hypervisor.
Lastly towards the cloud:
At present, cloud server works wonder in redefining modern data center. The virtualization technology has often underlies cloud computing to be quite powerful and real. Even though IBM introduced it at around 1960s, but it evolved to a completely new level few years’ back. Nowadays, web design and hosting companies have well integrated this technology into data centers, known as IaaS. This helps in reducing software and hardware footprint and passed savings back to customers, with the cloud server model.
