Virtual Private Server (VPS) Solutions


vps hosting

VPS Solution is offering scalability, robustness, power and control. It is more suitable for those organizations which execute customized programs.

Top server solutions provider:-

1&1, Hostpapa, Godaddy are few of the best VPS solutions providers. VPS Solution provides facility to increase and decrease amount of storage which is as per as the business requirement. Companies who are using VPS solutions monitor each and every VPS account to resolve many issues before they affect any website. They also deliver a platform that makes virtual environment effective.

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:

  1. Full virtualization: – Hypervisor ensures that each virtual server has its own entity and exact processing power is distributed to each virtual server.
  2. Para Virtualization: – There is less dependency upon the hypervisor to monitor and allocate the proper amount of processing power.
  3. 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’.
  4. 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:

  1. Unmanaged VPS hosting
  2. Semi managed VPS hosting
  3. 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:-

  1. VPS provides a complete control of web hosting experience.
  2. It has facility of both Linux and Windows operating systems.
  3. It has maximum uptime for business-critical applications.
  4. It performs well with 99.95% of network availability.
  5. It is flexible to install compatible software and applications.

Why virtual private servers: –

There are 5 reasons why VPS may be the solution:-

  1. Growth Potential : It should be strong by ensuring that the provided site will remain available and ready for business whenever there is an opportunity.
  2. 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.
  3. 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.
  4. Support : VPS hosting package comes with support. It provides 24/7/365 support for customers whenever they needed.
  5. 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.

Differences:

  1. VPS is less expensive than cloud servers.
  2. VPS has less server power than cloud.
  3. 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.

Virtual Web Hosting


If you don’t want to choose a share hosting then you can go for virtual hosting so a virtual server gives you most of the advantages of a dedicated server at a fraction of the price. The web hosting service takes advantage of the fact that few small to mid-size web sites need the full resources of a machine and puts several web sites on the same server.

There are also marked differences between shared web hosting and virtual server hosting. While a web hosting company puts multiple accounts on the same server in both kinds of hosting, the resources of the machine are portioned out differently.

Having your own operating system also means that you can make changes to it that you may not be allowed to make on a shared server. This allows you to customize the way your web site behaves almost as if you were on a single dedicated machine without worrying about affecting other customers on the same machine.

Prices for a virtual server range from about few dollars a month to more dollars a month and up. Your own dedicated server will run several hundred dollars a month, depending on the options that you choose for it.

so you can choose according to your demand.

Unrestricted Dedicated Server


Choosing the right web server will be one of the most important decisions you will ever make with your online business. Why? Because the web server you choose will literally make or break your online business.

Two types of servers are Virtual Web Hosting and Virtual Private Servers.

Virtual Hosting
Virtual Hosting is also known as Shared Web Hosting, where you are sharing the physical server and a single set of software applications with other users. Advantage to Virtual Hosting is that you have a powerful, reliable, and professionally managed server without having to have advanced technical skills, making it ideal for an individual, small business, or even a beginner webmaster.

The disadvantage of Virtual Hosting is that you are sharing the server with other users, which are configured and controlled by an administrator, not you. So basically you have your hands tied behind your back, because you have to contact the administrator every time you have to adjust or change your configuration settings Virtual Private Servers

A Virtual Private Server is a single server that is partitioned at the root into multiple dedicated servers. This allows you to share the cost of the network connectivity, hardware, and system maintenance with other hosting customers, while maintaining your flexibility and freedom.

The real advantage of Virtual Private Servers is that they allow you to have complete control and they have the security advantages of a dedicated server at the fraction of the cost. You have access to the virtual root, Telnet, web configuration files, and full CGI-BIN access. I can’t forget to mention that you also have access to your password, aliases file, and send mail configuration file.
There is one disadvantage with Virtual Private Servers, you need to have some program knowledge to control and configure the settings. Which one is right for you? Well, that all depends on you and the size of your network.

If you have or plan on having just one web site and have absolutely no programming knowledge, then Virtual Hosting is the recommended and economical way for you to go.

If you have a larger network that requires multiple web sites and you have some programming knowledge, then a Virtual Private Server is ideal for you. You can host up to 50 web sites on a Virtual Private Server account, instead of having multiple Virtual Hosting accounts, which is not as economical.

When it comes time to get a web server, make sure that the server fits your needs and that it supports the essential software for a prosperous online business.

SHARED WEB HOSTING


A shared web hosting service or virtual hosting service or derive host refers to a web hosting service where many websites reside on one web server connected to the Internet. Each site has its own section/place on the server, to keep it separate from other sites. This is generally the most economical option for hosting, as many people share the overall cost of server maintenance.
In general shared hosting will be inappropriate for users who require extensive software development outside what the hosting provider supports. Almost all applications intended to be on a standard web server work fine with a shared web hosting service. But on the other hand, shared hosting is cheaper than other types of hosting such as dedicated server hosting. Shared hosting usually has usage limits and hosting providers should have extensive reliability features in place.
Shared hosting typically uses a web-based control panel system, such as cPanel, Plesk, H-Sphere or one of many other control panel products. Most of the large hosting companies use their own custom developed control panel.
In shared hosting, the provider is generally responsible for managing servers, installing server software, security updates, technical support, and other aspects of the service. Most servers are based on the Linux operating system and LAMP (software bundle), which is driven by the reliability and security of open source software such as Linux and Apache. Some providers offer Microsoft Windows-based or FreeBSD-based solutions but both have same functionality.
There are thousands of shared hosting providers. They range from small design firms to multi-million-dollar providers with hundreds of thousands of customers. A large portion of the shared web hosting market is driven through pay per click advertising or Affiliate programs.
Shared web hosting can also be done privately by sharing the cost of running a server in a colocation centre; this is called cooperative hosting.

Shared hosting is of two types name-based and IP-based

In IP-based virtual hosting, also called dedicated IP hosting, each virtual host has a different IP address. The web server is configured with multiple physical network interfaces, or virtual network interfaces on the same physical interface. The web server software uses the IP address the client connects to in order to determine which web site to show the user.
In name-based virtual hosting, also called shared IP hosting, the virtual hosts serve multiple hostnames on a single machine with a single IP address. This is possible because when a web browser requests a resource from a web server using HTTP/1.1 it includes the requested hostname as part of the request. The server uses this information to determine which web site to show the user.
One of the most obvious setbacks of shared hosting is the price factor. Since it is very cheap, many people will not care about the disadvantages on their websites and they will want to bandwagon into these services. Due to large number of people using the services, the amount of resources that may be made available to individual users is usually limited. If one of the peer sites is using excessive amounts of the server resources, you will be facing trouble in terms of usage of your own website.
Another problem that is associated with shared hosting is the sharing of IP addresses. If you share an IP address with a company that has experienced some trouble with internet search providers, your website will also be automatically disqualified from the services of the search providers. The customer service that is provided by the companies providing the shared hosting services will also be wanton. This is because most of the companies will place greater emphasis on clients who opt for managed or individual hosting. This is because most of these clients bring in larger amounts of money and will naturally have priority.
Shared hosting plans are generally the easiest and most economical for personal and small business websites. A lot of e-commerce sites, blogs, professional portfolios, and other small sites are hosted on shared hosting.

VIRTUAL WEB HOSTING


Virtual hosting is a method for hosting multiple domain names (with separate handling of each name) on a single server (or pool of servers). This allows one server to share its resources, such as memory and processor cycles, without requiring all services provided to use the same host name. The term virtual hosting is usually used in reference to web servers but the principles carry over to other internet services.

There are two main types of virtual web hosting, name based and IP based. Name based virtual hosting uses the host name presented by the client. This saves IP addresses and the associated administrative overhead but the protocol being served must supply the host name at an appropriate point. IP based virtual web hosting uses a separate IP address for each host name and it can be performed with any protocol but requires a dedicated IP address per domain name served. Port based virtual hosting is also possible in principle but is rarely used in practice because it is unfriendly to users.

Name based and IP based virtual hosting can be combined, a server may have multiple IP address and serve multiple names on some or all of those IP addresses.

Virtual web hosting allows many websites to be hosted on the same server(s), leading to competitive pricing for the end user and for simplified management for all parties involved. Without the efficiency of virtual web hosting, it would be impossible for the Internet to scale as the hardware and maintenance costs would be unrealistic for the vast majority of website owners.

For large websites with a significant number of visitors and page views, virtual web hosting may not be the best solution because the resources required by the website can be very significant, often resulting in the need for an entire server, or for very large sites, multiple servers. However, virtual web hosting benefits entry level users with small websites who have a low budget and only require basic server resources that can be shared with other sites.

Basic virtual web hosting plans should incorporate the following features; adequate disk space and bandwidth, email accounts and an administration control panel. The control panel has multiple features simplifying the process of web design and management for regular folks who are not tech savvy. The control panel will allow for easy installation and administration of popular web software like WordPress, Google Analytics, forum software, etc. The operations for each domain name remains independent from other domains hosted on the same virtual web hosting server. Administration of the domain’s resources is conducted on the server side via a web browser interface.

With virtual web hosting, the user only has access to the portion of the server where their website(s) reside. For instance, users can upload photos to their blog or post articles and HTML files. However they are not granted rights to conduct processes like increasing disk space or bandwidth, as those details are controlled by the hosting package that the user has purchased. Most virtual web hosting packages also allow for administration of advanced services such as MySQL databases or PHP.

LINUX VIRTUAL HOSTING


Linux is a Unix-like computer operating system assembled under the model of free and open source software development and distribution. In fact it was derived from UNIX. The defining component of any Linux system is the Linux kernel, an operating system kernel first released October 5, 1991 by Linus Torvalds. Linux system distributions may vary in many details of system operation, configuration, and software package selection.

Linux is the preferred operating system in the web hosting world. It comes for free, it’s much more secure than Windows, and being open source-based, it’s easy to modify as well. Used by the majority of the web hosting companies, Linux was the natural OS environment choice when the concept of the virtual machines was introduced.

Very soon virtual machines became very easy to create and use. Plus, any operating system out there could run on a Linux-based machine. This solved many compatibility problems, which had existed between Linux and Windows for ages.

Virtual hosting is a method for hosting multiple domain names (with separate handling of each name) on a single server (or pool of servers). This allows one server to share its resources, such as memory and processor cycles, without requiring all services provided to use the same host name. The term virtual hosting is usually used in reference to web servers but the principles carry over to other internet services.

When people realized that LINUX allow them to offer customers the ability to be hosted on a virtual server, which had all the access benefits of a stand-alone dedicated server, the term “Linux virtual hosting server” quickly appeared. The Linux-based virtual hosting solution allows the user to run their own instance of a Linux distribution, such as CentOS, Debian or Ubuntu on their machine, as if it was a real server offering complete root access.

Virtualization is all the rage these days, with a lot of different solutions available – from hardware virtualization to OS virtualization. Different software solutions are available to perform the needed operations as well. The virtualization method is especially applicable in the web hosting field – it allows hosting providers to reduce the total number of the servers used, improve their services, reduce their prices and offer a brand new service – Virtual Private Servers.

The Linux Virtual hosting plans are reliable and powerful enough to host from a small e-commerce site to a huge corporate portal. Each server also comes with a free domain reseller account and other facilities like high bandwidth and large storage space all this at a affordable price.

SHARED HOSTING


Shared hosting, sometimes called shared services or virtual hosting, is simply when multiple web sites share the same server, thus reducing the cost for everyone.

With a shared hosting account, your site will usually be on a server with hundreds of other web sites. That may sound like a lot, but it usually works out extremely well because most sites don’t generate enough traffic or use enough resources for it to become a problem.

Share hosting is suitable for personal sites, small businesses, and even medium sized businesses if their hosting needs fit within the parameters of a small business.

Most shared hosting providers offer substantially more disk space, data transfer, and email accounts than most people or businesses need. If every site used their quota, shared hosting would not work. But since few do, it actually works out quite nicely.

The only real problem with shared hosting is if the web host oversells. Overselling means the host has put too many sites on one server. A good server usually has at least a gigabyte of memory, but if thousands of sites have to fight it out for memory, CPU cycles, and bandwidth, it means all the sites will be slow. Fortunately, any good host will prevent this from becoming a problem in the first place.

The hosting service must include system administration since it is shared by many users; this is a benefit for users who do not want to deal with it, but a hindrance to power users who want more control. In general shared hosting will be inappropriate for users who require extensive software development outside what the hosting provider supports. Almost all applications intended to be on a standard web server work fine with a shared web hosting service. But on the other hand, shared hosting is cheaper than other types of hosting such as dedicated server hosting. Shared hosting usually has usage limits and hosting providers should have extensive reliability features in place.

Shared hosting typically uses a web-based control panel system, such as cPanel, DirectAdmin, Plesk, InterWorx, H-Sphere or one of many other control panel products. Most of the large hosting companies use their own custom developed control panel. Control panels and web interfaces can cause controversy however, since web hosting companies sometimes sell the right to use their control panel system to others. Attempting to recreate the functionality of a specific control panel is common, which leads to many lawsuits over patent infringement.

Shared web hosting can also be done privately by sharing the cost of running a server in a colocation centre; this is called cooperative hosting.

Shared hosting is of two types name-based and IP-based

In IP-based virtual hosting, also called dedicated IP hosting, each virtual host has a different IP address. The web server is configured with multiple physical network interfaces, or virtual network interfaces on the same physical interface. The web server software uses the IP address the client connects to in order to determine which web site to show the user.

In name-based virtual hosting, also called shared IP hosting, the virtual hosts serve multiple hostnames on a single machine with a single IP address. This is possible because when a web browser requests a resource from a web server using HTTP/1.1 it includes the requested hostname as part of the request. The server uses this information to determine which web site to show the user.
