Virtual server schemes:-
Virtual server is a server which shares computer resources and execute power with other virtual servers. Virtual servers have ability to share resources among each other is known as Hypervisor. There are four types of schemas:
- Full virtualization: – Hypervisor ensures that each virtual server has its own entity and exact processing power is distributed to each virtual server.
- Para Virtualization: – There is less dependency upon the hypervisor to monitor and allocate the proper amount of processing power.
- Operating System (OS) Level Virtualization: – There is no need of Hypervisor with this. All virtual servers use same kind of OS. This is also called ‘homogenous virtualization environment’.
- LDAP Virtual Directories: – These directories are used to create both Internet and Intranet related applications. This is possible only by sharing useful information. This includes data about employees, services, systems.
Time-sharing model in VPS (use of hypervisor):-
The OS basically shares access to the resources but there is a single machine which is being shared. As the resources are shared under time-sharing model, virtualization is providing a higher level of security as individual virtual servers are isolated from each other. This is important because it allows businesses to run their legal application on older versions of an operating system and can be rebooted independently. Single server is partitioned into multiple computers. The physical server runs a hypervisor which has task of creating, releasing and managing the resources of “guest” operating systems or virtual machines.
Example of VPS servers:-
OpenVZ, Virtuozzo, Xen or KVM, VMware and Hyper-Vs
Virtual private server: a deep insight:
VPS service is designed to be exclusive. Multiple customers are allowed to share the resources of one server, with high degree of security. Customers of VPS have “root” level access. It is quite powerful hosting solution which needs high server resources at lower cost. Each and every virtual server can run its own OS, and each server can be rebooted independently. VPS services are scalable and customizable as per business needs. For Linux OS VPS server is used with APACHE, MySQL, PHP. For Windows VPS server is used with ASP or ASPX pages accessing databases or SQL server database MSAccess.
Types of virtual private server:-
There are three types of VPS hosting:
- Unmanaged VPS hosting
- Semi managed VPS hosting
- Managed VPS hosting
Unmanaged VPS hosting: In this, the whole server administration and the responsibilities of essential configuration and management of VPS are the responsibilities of end users. Users have to gain some knowledge in administration of Linux servers.
Semi managed VPS hosting: Virtual servers include re-installs of the OS and the control panel, adding additional IP addresses, configuring firewall rules, DNS management.
Fully managed VPS hosting: VPS support includes knowledge of everything related to the server such as assisting users with questions and try to overcome VPS related problems maintaining the virtual server’s security.
Advantages of virtual private server:-
- VPS provides a complete control of web hosting experience.
- It has facility of both Linux and Windows operating systems.
- It has maximum uptime for business-critical applications.
- It performs well with 99.95% of network availability.
- It is flexible to install compatible software and applications.
Why virtual private servers: –
There are 5 reasons why VPS may be the solution:-
- Growth Potential : It should be strong by ensuring that the provided site will remain available and ready for business whenever there is an opportunity.
- Cost Control : Large businesses have a big budget so there is a need of dedicated server. If cost control is there then VPS would fit in the budget while giving great web hosting services. VPS provides the advantages of dedicated server without making hardware and maintenance costs.
- Security : VPS provides an individual IP address and unique –to-user password protected entries. Multilayered protections built into the system makes VPS safer and secure for business hosting.
- Support : VPS hosting package comes with support. It provides 24/7/365 support for customers whenever they needed.
- Control : VPS provides control over content of site and applications which are running. By logging into admin, one can upload edit content, documents, run new applications and operate business anytime, anywhere.
A bridge from shared to dedicated:
VPS run on a shared piece of hardware. A multicore host is configured to provide dedicated pools of memory which are shred, single or multiple cores and hard disk storage. Some hosts provide a selection of GNU/Linux OS, some offer Windows server in one or more forms. The storage of VPS is constant. It means if virtual machine or hardware crashes or loses power, it would resume back after rebooting except hard drive failures.
VPS or cloud: similarity and differences :
Similarities: Though both are not similar but still Cloud hosting has some commonality to VPS hosting in several ways. There may be minimum or maximum server size configuration. They both are running as a virtual server in an environment. Price service is associated with the machine and the resources like CPU RAM which are guaranteed to be available.
- VPS is less expensive than cloud servers.
- VPS has less server power than cloud.
- If a physical server fails VPS can be rebooted without affecting other VPSs on shared server, while cloud servers are migrated to another physical server.
