Virtual Private Server – the next best thing to dedicated servers!
Virtual Private Servers or VPS is a term coined by the web hosting industry to describe virtual fully-functional partitions in a main server. Although it is not a separate physical machine, the partitions are made in a way that each unit works as an independent functional server. It is a great option for customers who want most advantages of dedicated hosting without having to shell out cost of owning a high-end server. VPS maintains privacy of a private machine as the server software applications are separately loaded in the partitioned system.
Recent trends show that webhosting solution is more popular among small and medium business owners, whose web requirements do not include an in-house dedicated server hosting. Moreover, dedicated server hosting is extremely costly, considering the amount of effort it would require to maintain a server. While the concept of shared hosting is perfect for such requirements, it has its own issues since CPU cycles and other system resources are also shared, which may cause performance issues. Therefore, VPS brings the best out of both shared and dedicated hosting options.
Working of a VPS
The design of a VPS works on two methods, which are used to create functionally independent partitions:
- Hypervisor: The hypervisor supervises or manages the resources related to the virtual servers where multiple operating systems can be installed and can be run on the same device. Hyper virtualization can be popularized by Xen, Microsoft Hyper-V, KVM and VMware ESX. Another name of hypervisor is Virtual Machine Manager(VMM).
- Container: Here each VPS is provided user spaces or a separate container. Container virtualization can be popularized by OpenVZ or Parallels Virtuozzo. Another name for this method is Kernel-based system.
Ease of managing a VPS
One of the persistent issues with shared hosting is the lack of flexibility in adding or removing resources. Based on the popularity and effectiveness of a web enterprise, the customer may want to modify his/her requirement. With VPS, resetting system allocations is extremely easy and users can change its system requirement at any given point of time. The resources which can be easily allocated or deallocated according to user requirements are:
- Hard disk space
- IP addresses.
VPS Hosting and the cloud
The principle behind cloud hosting includes spreading of resources among more than two servers at remote areas. The actual address and state of the stored data are unknown to the user but he can easily access the stored data or the system as per his need. This is because cloud hosting is similar to VPS in its core concept. While separate machines are connected over the Internet to form a cluster of machines, its computational power is then distributed among nodes accessing it. Thus, the cluster of machines acts as a single machine, while the allocation to each node/client is the functionally-independent partition.
