Abstract
The Quality of Service has become an essential matter now that Internet services have come into general use. Even temporary failures may cause user dissatisfaction, resulting in customer loss for the Internet Service Provider. Providing uninterrupted service sets high requirements for service production systems. There is also a need for methods for risk assessment of such systems. The design of a networked computing system, which provides Internet services, can be created according to several recommendations and standards. In addition, there are several frameworks and methods for risk assessment. Several reference standards are introduced in this thesis to provide foundation for system design and analysis. In this thesis, I have used a dependability framework to collect the most important properties (availability, reliability, maintainability and security) of Internet service production systems for my analysis. To provide a generic view, I have created a few simple structural models first. Fault trees and reliability block diagrams provide additional means of considering redundancy options among other design
