SYSTEM OF SYSTEMS FOR QUALITY-OF-SERVICE OBSERVATION AND RESPONSE IN CLOUD COMPUTING ENVIRONMENTS

ABSTRACT

       As a cloud computing systems refers to the demand delivery of IT resources via the internet with pay as you go pricing. A cloud offers many services to the end users such as software, infrastructure and platform go on. Along with these opportunities come challenges, particularly to service providers and operations centers that struggle to monitor and manage quality of service (QoS) for these services in order to meet customer service commitments. Traditional approaches fall short in addressing these challenges because they examine QoS from a limited perspective rather than from a system-of-systems (SoS) perspective applicable to a net-centric enterprise system in which any user from any location can share computing resources at any time. This paper presents a SoS approach to enable QoS monitoring, management, and response for enterprise systems that deliver computing as a service through a cloud  computing   environment.

Service is often considered, such as error rates, bandwidth, throughput and transmission delay.

Cloud computing provides one possible method to meet this challenge by reducing cost through shared computing resources while distributing data to multiple end users efficiently. A concrete example is provided for application of this new SoS approach to a real-world scenario (viz., distributed denial of service). Simulated results confirm the efficacy of the approach. Present approaches to mitigate these issues are not sufficient to ensure quality of service (QoS) for end users. a complex cloud computing environment is subjected to a distributed denial-of- service (DDoS) attack. Section V details the experimental results obtained in the prototype system created to verify the SoS approach.
