Abstract

Users of various information systems and computer services often come upon a concept cloud computing. This concept combines a lot of various web hosting services, from simple web hosting to high performance computer sources. Individuals, smaller companies and bigger corporations are learning that it is often much cheaper to rent a computer capacity on a remote location than setting their own datacenter and do its maintenance. The difference is the most distinctive for smaller companies and individuals. Because of the wide spread virtualization technologies sharing of computer sources is much easier and it has enabled the development of the companies that offer hosting of web pages, blogs, storage sources, e-mail servers and virtual servers. We are going to limit ourselves to smaller companies or institutions that need web pages and web classrooms for their work and presentation. For this purpose they hire web servers where they set up their portals and they maintain it dynamically. Most users are not familiar with web technologies that support a simple web page. In this thesis we will get to know web technologies in terms of web hosting. How much knowledge users need to use a dynamic web page and how much knowledge a system administrator needs to support all infrastructures that are in charge of undisturbed web page operation. We will introduce different types of virtualizations without which we cannot imagine so many web services suppliers. We will find a reasonable solution which will simplify a complex system administration for users, who want the biggest flexibility without a lot of knowledge, as well as for a system administrator who has to have a lot of knowledge for a flawless operation.
