Dedicated Server Hosting
Dedicated Server Hosting
Dedicated Hosting refers to Web Hosting in which the environment with which you are provided is a dedicated one, meaning that you are not sharing it with anyone else. Dedicated servers normally come under this category, since you are leasing a physical server from a web host and the resources contained within that one server are not shared between multiple users; however, a new technology known as VPS (virtual private servers) could also be delegated to this category since the environment which they provide is dedicated, but at the same time is still virtual since the VPS is sharing a physical node with other VPS - the only resource which is only being constantly shared is the CPU. Dedicated Hosting solutions are normally taken up by companies or individuals who need their hosting environment to be customized, for example with the use of certain programs which might not be available on shared hosting packages, but in this case since you have your own dedicated environment you are able to install what you want. Dedicated Server Hosting solutions are only normally chosen in a situation where a return can be made easily, since both VPS servers and dedicated servers are quite costly.
Supported Operating Systems
With Dedicated Server Hosting solutions, you are normally able to choose any operating system to be installed on your server since your choice will not have any effect on other users or customers; one thing to note is that if you go with a VPS your operating system choices are generally restricted to those which are support by both the VPS partitioning software and the physical hosting node. Cost, support and skills are also factors which can effect the choice of operating system; for example, you could be restricted from going with Windows Server 2003 because it is too costly for you, and you don’t have the necessary skills to administer a Windows server - your web host might also not support Windows Server 2003. If you find either of those three a limitation, then you could always opt for an open source Linux distribution; this is because open source means free, and because of this you are normally able to find a mass of online forums and e-books which give you support on how to configure certain OS settings. The application or content that you are wanting to host might also put a limitation on your choice of operating system; for example, you might have an ASP.NET web application which would mean that you are stuck with choosing Windows Server 2003 as your server operating system. Finally, the security of the operating system should always be a key factor affecting your final choice of operating system; this is because you do not want your system to end up being hacked, most Linux distributions can’t be affected by viruses but by things called rootkits which can lead to an OS reload if a server becomes infected with one; there are many viruses for the Windows operating system, but with the correct precautions and protection you should not face any problems.
Bandwidth and Connectivity
Bandwidth is assigned to each and every server by the upstream provider, and is normally given in an amount; connectivity refers to the different peers with which you are connected to, the more peers you are connected to, the more likely it is that your website will have a fast connection around the entire world. Most peers connect to the main bandwidth exchanges in the world, an example of which being LINX - the UK’s main bandwidth exchange which is based in London. Bandwidth is normally assigned per GB (gigabyte), however until quite recently it was still being assigned as MB (megabytes) - the change being because of the increasing amount of internet traffic; some providers hand out unmetered data pipes which basically means that the servers on the end of that data pipe have an infinite amount of bandwidth (although this is technically not possible). Service Level Agreements, which are better known as SLAs, are normally provided for network uptime and come along with dedicated servers; an example of the content contained within an SLA would include something along the lines of customer credit for the network being down for longer than ‘x’ amount of time. Some dedicated hosting providers claim to be able to provide 100% uptime on their networks, this is normally achieved by the use of multiple connections to a mix of bandwidth and connection providers.
Management
Most Dedicated Server Hosting providers are able to provide management for dedicated and VPS servers to a certain extend, normally for node, network and included software problems. Since the environment given is a dedicated one, the customer is expected to have a certain amount of knowledge in order to be able to keep the server in working order and to be able to carry out general tasks such as maintenance. Support for the node would cover issues such as problems with the physical node and any hardware to which it is connected as well as software and hardware upgrades and maintenance; network support would cover general issues with the network as well as the maintenance of routers and switches; included software support would cover the base operating system as well as any software which you chose to be installed at the time of purchase, for example a control panel. Simple tasks such as server reboots, and system reload in the case of VPS servers, will normally be carried out for free by the host at no extra cost.
Security
Most Dedicated Servers and VPS servers are normally located behind both a software and hardware firewall. Most also contain virus scanners and rootkit hunters so that any malicious programs that do find their way onto client servers are found and removed as soon as possible. In the case of VPS servers, the nodes normally have some sort of virus scanner which means any VPS which is found to have a virus will be shut down or sorted in the correct manner Some types of software are banned from being used on the networks of some hosts for the reason being that they can compromise both the security of the client’s server and the hosts network.
Software
With dedicated hosting, you are normally able to install your own software on your server since it is a dedicated environment and your actions will most likely not effect anyone else. Some hosts allow you to purchase licenses for certain pieces of software at the same time when you purchase the server - this can prove to be an advantage for the customer since the host might be selling licenses cheaper, which is normally the case if they are a license reseller. Over the past few years, some software vendors have seen the advantages which the dedicated hosting market could bring them, meaning that many have decided to try and have their software bundled with dedicated server packages as well as setting up special pricing structures for both VPS and dedicated server solutions. Some hosts are able to offer Microsoft software through the giant’s ‘SPLA’ (service provider license agreement) which allows providers to offer Microsoft software on a monthly basis, which can cut the cost down for customers. Most hosts also offer software such as control panels from vendors including SWSoft and cPanel to allow you to manage your server effectively. One thing to note is that software such as IRC servers are not allowed on many host’s networks for the simple reason that they can easily trigger ddos attacks against the host which could lower the network speeds for all customers.

Well, if any website is getting serious traffic, for obvious reason the dedicated hosting is one of the best solution since at this stage your website need enhance security feature, more resources, greater stability and flexibility.
