A shared hosting server is one in which a number of sites are hosted on one server and the resources like RAM, disk space and the processing unit (CPU) are shared by all the websites. A shared hosting package is quite cheap. A dedicated hosting server is one in which only one website is hosted on one server. The resources are available to the website all the time and are solely for that website. A dedicated server is quite expensive as compared to a shared hosting server. A VPS hosting package is between both shared hosting and dedicated server in features and also the cost.
The operating system and the installed services that are provided in a shared hosting server are solely the provider’s choice. Whereas in a VPS hosting package there are more than 30 Linux operating system templates to choose from. In a VPS hosting you can choose to install any service that you require. The inherent features of shared hosting make it difficult to secure completely. It is because multiple users have the permission to upload and download files and these files might be supporting the account of some other resource. So there is always a possibility that a malicious user might exploit the vulnerability and access the data of other users. A VPS hosting is more secure as in its virtual environment there are independent file systems and the administrators are empowered to make the implementation of completely secure configurations. Apart from these differences there are a few similarities between the two types of hosting servers, like
• Both the hosting services use the platform of a single server to provide services to multiple users.
• Both the hosting packages are an economical alternative to dedicated hosting.
When you use a dedicated server you have full control over the physical server and all the resources are completely accessible to you. With a VPS hosting package you have to share the processing capacity with other hosts and have dedicated access to the RAM and the disk space. A VPS offers you greater flexibility as it is very easy to move one server to other. As your requirements grow you can move your virtual server to bigger and better servers so that you ensure that your website performs to the level that you want. The cost of both the hosting packages is the most significant difference between the two. The cost of dedicated hosting is almost 10 times that of a VPS hosting. There is not much difference between the control and customization that is offered by both dedicated hosting and VPS hosting. With a VPS hosting package you will not have to pay for resources that you are not using for your website.
A VPS hosting package is perfect for those websites which have dynamic content and experience a lot of traffic. Also if you have a large number of files on your website then VPS hosting is perfect for you. A VPS package is a powerful package and with it you can do a lot more than what shared hosting offers you and that too at a price which is lower than the dedicated hosting packages.
