Implementation of scalable online video services

Abstract

The subject matter of this thesis is online video services and particularly the implementation of such services and the various technologies that are involved. This thesis aims to provide an overview of the most significant technologies and components that are fundamental for the implementation of typical online video services. It will also introduce the Media CMS, which is a platform for building online video services. To some extent the subjects that are covered in this thesis function also as a summary of the topics that needed to be researched for the implementation of the Media CMS. Media CMS has a strong emphasis on extensibility, flexibility, performance, and security, and this thesis describes the architectural decisions and design principles that were employed to attain those goals. This thesis also describes the most significant components of the system and the mechanisms and structures that are used to utilize and combine the technologies and off-the-shelf components that will be described. It will also describe some of the most significant challenges and problems that needed to be solved during the implementation of the system.
