The term virtual server refers to a number of distinct technologies. Here we examine the type of virtual server known as the Virtual Private Server (VPS), otherwise called a Virtual Dedicated Server (VDS). This type of virtual server is a method of dividing a single server machine into multiple servers by employing virtual machines. Each virtual server has its own operating system and server administrators can reboot and operate on them independently.

Data centers have financial and physical limitations. VPSs overcome some of these limitations by reducing the physical footprint and achieving cost effectiveness through consolidation. Shared server solutions are an alternative to a VPS that also help to overcome these limitations. The advantages and disadvantages of a VPS contrasted against a shared server solution.

The core advantages of a VPS are cost, independence, insulation, performance and security. A VPS essentially provides all of the benefits of operating one server per machine and insulation, in a virtual way, provides the same boundaries that exist between servers in separate machines. This limits the disadvantages that the system introduces. It also allows performance to be higher because there are no bottlenecks introduced from the coordination of resources. In addition, there is no threat of a compromised server influencing any of the other servers on its machine.

One of the core disadvantages of a VPS is the ability to adapt to load. During periods of high traffic, a server in a shared environment can borrow the resources of its fellow servers in order to handle the additional load. In general, VPSs and one server per machine environments are more wasteful than shared solutions. Resources often go unused and the data center must account for far greater resources than they would use in a shared scenario due to individual peak levels.

The term is used for emphasizing that the virtual machine, although running in software on the same physical computer as other customers’ virtual machines, is in many respects functionally equivalent to a separate physical computer, is dedicated to the individual customer’s needs, has the privacy of a separate physical computer, and can be configured to run server software.

Virtual dedicated server (VDS) is also used as synonyms of VPS. However, the latter also occasionally indicates that the server does not use burst/shared RAM through multiple machines and may use individual CPU cores. The term cloud server is also used to describe the same concept, normally where such systems can be setup and re-configured on the fly.

Virtual dedicated servers offer many of the capabilities and features of dedicated servers, including admin (root) access and dedicated IP addresses, but at a much lower price. However, as a virtual dedicated server is, indeed, virtually dedicated, the customer in fact shares the server space with a small number of other customers. But because each virtual dedicated server is effectively isolated from other accounts on the server, the user has full control over the server space. As well, virtual dedicated server plans feature very high performance and available disk space and bandwidth.

Virtual dedicated servers are particularly useful for companies and individuals that run higher-traffic Web sites or complex applications and thus need the bandwidth, consistent performance, and flexibility of a virtual dedicated server.

Virtual Dedicated Server (VDS) Technology is a new technology based on the concept of partitions on mainframes and advanced resource scheduling to divide a computer into many virtually isolated servers. A VDS simply put is, a server that runs inside another server. Each VDS acts like a dedicated server but shares the same hardware.

VDS technology completely isolates each VDS, creating a more secure and reliable hosting environment. Each VDS has its own isolated disk space, guaranteed network interface bandwidth, guaranteed CPU allocation, RAM and operating system. If a VDS on the same physical server crashes, the other accounts on the server are protected and remain unaffected. It is not possible for any account to use up the entire RAM, disk space, network bandwidth, CPU cycles, or any other resources of the Hosting Server. Neither is it possible for one account to view/edit the files of any other account.

The VDS allows small Internet providers to set up their individual hosting application while avoiding them extra costs relating to the hosting platform and a need to worry about the server operation.

A managed server is your own dedicated hosting service that also provides data storage services. In addition, managed servers have their own maintenance and backup systems.

Managed dedicated server is a service that includes the hardware, software, and ongoing upkeep of a dedicated server. The dedicated server industry often bundles additional services and products with the servers to provide a deeper level of management.

Managed Dedicated Server providers employ full-time system administrators that maintain dedicated servers. A managed dedicated server allows for not only more productivity, but eases your mind about a multitude of other issues, sometimes unforeseen by the Client and even the developers working on functions of the dedicated hosting server. Security is a very large factor in choosing not only a Managed dedicated hosting company, but also in choosing a managed dedicated Server. Management features include.

• Software updates
• Operating system updates
• Firewall services
• Backup services
• Advanced technical support
• Application deployment
• Database management
• Server monitoring and recovery
• Telephone based support
• Advanced configurations
• Control panel software

The biggest reason to choose dedicated server hosting is the bandwidth guarantee. Running out of bandwidth can slow down site access or make it inaccessible.

It is important not to confuse managed servers with dedicated shared servers. Shared servers only lease out a part of their memory space to host the clients’ website or websites. Managed servers are solely for their clients; they can use as much of the space as they please. A managed server affords the client the maximum amount of resources for the best allocation of their time and energy.

Needless to say, managed servers are only best for medium to large businesses. If you only have a small personal website, you probably do not need a managed server unless you are very worried about possible down-time. This is not a baseless concern, but unless you take your personal website and turn it into a business, you will be better off sticking to a smaller hosting service.

The one big advantage of managed servers is that they relieve the clients of having to maintain the servers themselves. As a matter of fact, the company that owns the server basically rents it out to clients, usually on a monthly basis. The company programs the server at the clients request, makes any changes and keeps it physically secure.

There are some disadvantages to managed servers, however. The largest disadvantage is the cost. Managed servers cost much more than ordinary hosting accounts. Companies want to recoup the costs of running multiple servers at once, and the most typical method is to charge high prices.

Over the last decade, IT has evolved from a competitive differentiator to a necessity, which explains why many businesses today are investing in it so extensively. As the IT evolution continues to expand at breakneck speed, businesses are increasingly turning to managed hosting solutions to stay ahead of the curve, reduce capital expenditure and allow their internal teams to manage business-critical initiatives instead of focusing on the systems that support them.

The biggest advantage to a managed server hosting plan is that you don’t have to hire an expensive server administrator to manage your server. You can focus your time managing your business and let the hosting company manage your server.

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.

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.

A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone. This is more flexible than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc. Server administration can usually be provided by the hosting company as an add-on service. Dedicated servers are most often housed in data centers, similar to colocation facilities, providing redundant power sources and HVAC systems. In contrast to colocation, the server hardware is owned by the provider and in some cases they will provide support for your operating system or applications.

Dedicated web hosting is beneficial while developing a complex business or a high-end e-commerce site as you will need more space and security – a web server dedicated to your business. They purchase or rent the hardware from the hosting company who then normally support and manage it. Internet connectivity is provided to the server.
Dedicated hosting in two flavors: managed and unmanaged hosting
Disadvantages of dedicated hosting services is responsibility. In most areas of life, with total control comes total responsibility, and it’s no different with dedicated hosting providers. With dedicated servers, the onus is on you to buy, install, and maintain the actual equipment – the dedicated servers – mounted in the dedicated hosting provider’s data center.

Fortunately, you still get the benefit of the dedicated hosting provider’s presumably top-notch, around-the-clock security over the dedicated servers physical premises, but you remain fully responsible for the security of your cyber-premises. Likewise, dedicated hosting providers will ensure that the dedicated servers in the building are all provided with redundant uninterruptible and backup power and environmental controls, but it’s you who must keep your machines and cables maintained and functioning in this idyll environment.

Advantages of dedicated hosting services:

Speed : If the traffic streaming through your shared server is slowing down your customers’ pace as they browse your site, it may simply be time to look for more dedicated hosting services. As it provides you with high speed as it has dedicated server which work for your site only.

Reliability : The limits to your control are nowhere more apparent than in the areas of reliability and security. It’s not simply that problems can arise: problems do arise. It’s the nature of the biz. And if you don’t have unlimited access to your own operating system as with dedicated hosting, dedicated servers, software and database apps, etc., there’s not much you can do when one arises.

Customizability : If your company is growing fast, you’re going to be changing many aspects of your web presence along with it. You may regularly need to tweak your disk space and bandwidth and experiment with using different applications to better serve your changing needs. Or the next leap up from your current plan has way more disk space and bandwidth than you need at the moment. With dedicated servers and a dedicated hosting package, you can make changes incrementally, step forward, step back, heck, step sideways if you need to and when you need to i.e. is you can change your disk space, bandwidth and you can even upgrade your server whenever you want and with whatever you want.

In large part, it’s the size and growth rate of your business that will dictate whether you need a shared or a dedicated hosting services. Affordability and personal time commitment are nice secondary considerations, but if your business is booming, you would do it a great injustice to try and save on a few bucks and few extra hours per week of your time in exchange for slower and poorer quality of service for your customers.

There is a common belief that you need a dedicated server if you want the flexibility to run different scripts and install custom software. That used to be the truth. Nowadays, virtualization software is so good that you can get almost the same flexibility at a fraction of the cost if you decide to make a Virtual Private Server to be the home for your website(s).

As the name indicates, cheap dedicated web hosting provides one server for each account. Dedicated web hosting is one kind of web hosting where one or more servers are committed to a single client. Web host offers the server for the clients and hence clients acquire those servers for lease. Therefore, web host provides the server machine, connectivity, required software and operating system to run the server. This type of hosting enables users with the freedom of choosing their own software. Hence, customers who have outgrown their shared hosting limits and still require more, prefer for this service. In fact, it is very flexible as the server administration is provided by the web host. With this hosting option, one can gain the benefits like reliability, flexibility, total control and security without having to work for it.

The most important factor related with dedicated servers is Security, and server security can be customized with the help of software or branded hardware firewall. Absolute server privileges enable the user to make any changes in terms of service that run within your dedicated server.

Dedicated Server hosting is represented as supreme selection of servers. Every individual server is logged by developed grade infrastructure which has an ensured maximum uptime. Some dedicated server providers comprises of service level agreement which is related to network uptime. 100& uptime guaranteed network is offered by some providers, whereas, the usual uptime is given between 99-100% for a best quality provider.

Types of Dedicated Servers : Dedicated hosting are classified into two categories

1. Managed dedicated server hosting
2. Unmanaged dedicated server hosting

Characteristics of dedicated web hosting

In web hosting business dedicated server is also known as dedicated server web hosting.

Dedicated server web hosting provides maximum control, flexibility, and responsibility. In this type of web hosting the entire server is your own. You’re not sharing it with anyone else. This allows for full use of all of the server’s resources and performance, yet that does come at a cost. Dedicated server web Hosting is more expensive than standard shared hosting. This type of web hosting is perfect for larger sites or those sites that simply need the reliability and performance, 100% of the time.

Dedicated servers of course come in all different configurations, as well as managed servers vs unmanaged servers. With Managed servers, the hosting company will handle all server administration (at a larger cost), whereas with unmanaged servers you will need to be well versed in those tasks.

A dedicated server web hosting includes an operating system a web server, related software and connection to the Internet, all housed in the web hosting company’s data centers. Dedicated server web hosting is typically required for a web site or a group of related company sites that develop a substantial amount of traffic. The server can usually be configured and operated remotely from the host company while still allowing for client customization. A dedicated server can be assigned to function only as a resource server and cannot be used as a client. It is important to note that the server is owned by the web host and you do not have physical access to it.

Dedicated server web hosting is beneficial while developing a complex business or a high-end e-commerce site as you will need more space and security – a web server dedicated to your business. It is purchased by a company when they want more control of their server. They purchase or rent the hardware from the hosting company who then normally support and manage it. Internet connectivity is provided to the server. Dedicated servers are most often housed in data-centres, similar to co-location facilities, providing redundant power sources and HVAC systems. The financial benefit with cheap dedicated server hosting is huge: large initial investments are not needed.

If you are looking for a cheap dedicated server web hosting, you should be careful when comparing packages. Things to consider are operating system, data backup and monitoring service, hardware options, space, bandwidth and technical support. Ask the hosting providers to give you a few websites for references, read hosting reviews and be sure that the price is affordable before you sign up.

When you need that kind of stability, you’ll want to look into dedicated web hosting. With a dedicated server, your site will be the only one being hosted and all of the server’s resources will be available at all times. This differs from a shared server, another popular option, where the resources are distributed to multiple sites being hosted. While that isn’t a problem for sites that don’t get high volumes of traffic, it does become an issue for those that do if that occurs because it can lead to crashes and downtime for the sites being hosted.

If your site is one that people are visiting in order to purchase products or services, this is something you cannot risk. However, a dedicated server can be expensive and it’s not something that is always in the budget. Ultimately, the investment in a dedicated server may prove to be worthwhile or the costs might not be an issue. But, some companies will find that they don’t have the staff or infrastructure in place to provide the support for their server. If this is the case, you’ll want to read up on a managed dedicated server.

If you are a small business owner and you are not a master of web-related knowledge and activities, the maintenance of a web site may be an intimidating task. In that case managed dedicated server may be the best option for you. A dedicated server is where your web site has its own storage space – its own entire server, actually – and you pay a predefined amount for bandwidth that you use. However, while this offers a great deal of customization, there is a certain level of maintenance involved as well. Between software updates, operating system updates, and security issues such as virus protection and firewall services, maintaining a web site, its content, and security can be a daunting task. Fortunately, a managed dedicated server is a great way to have the benefits of a dedicated server without the demands of maintaining it.

With a managed dedicated server, you get the reliability that you need but the maintenance and support is provided by the web hosting company.

When you use managed servers, the web hosting provider will have a member of their team keeping your site running on a healthy level. This means that all those maintenance issues described above are taken care of for you. This is very advantageous to those business owners that do not understand all the technology behind how a web site functions. You can save the time associated with learning how to perform these activities and focus on running your business. And with someone else, a paid web hosting professional maintaining it for you, you have the peace of mind knowing that you are not sacrificing the performance of your web site or the security of your customer transactions or content.
