1. 1. A Middleware for Self-Managing Large-Scale Systems

   Författare :Constantin Adam; Rolf Stadler; Arun Iyengar; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autonomic computing; self-organization; decentralized control; web services; quality of service; Telecommunication; Telekommunikation;

   Sammanfattning : This thesis investigates designs that enable individual components of a distributed system to work together and coordinate their actions towards a common goal. While the basic motivation for our research is to develop engineering principles for large-scale autonomous systems, we address the problem in the context of resource management in server clusters that provide web services.

3. 2. Scalable Self-Organizing Server Clusters with Quality of Service Objectives

   Författare :Constantin Adam; Rolf Stadler; Giovanni Pacifici; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikation; Autonomic computing; self-organization; decentralized control; web services; quality of service; Telekommunikation; Telecommunication; Telekommunikation;

   Sammanfattning : Advanced architectures for cluster-based services that have been recently proposed allow for service differentiation, server overload control and high utilization of resources. These systems, however, rely on centralized functions, which limit their ability to scale and to tolerate faults. LÄS MER

4. 3. Adaptive Real-time Monitoring for Large-scale Networked Systems

   Författare :Alberto Gonzalez Prieto; Rolf Stadler; George Pavlou; KTH; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Large-scale networked systems, such as the Internet and server clusters, are omnipresent today. They increasingly deliver services that are critical to both businesses and the society at large, and therefore their continuous and correct operation must be guaranteed. LÄS MER

5. 4. Performance anomaly detection and resolution for autonomous clouds

   Författare :Olumuyiwa Ibidunmoye; Erik Elmroth; Ewnetu Bayuh Lakew; Rolf Stadler; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud Computing; Distributed Systems; Performance Management; Anomaly Detection; Quality of Service; Performance Analytics; Machine Learning; Computer Systems; datorteknik; business data processing; administrativ databehandling; Computer Science; datalogi;

   Sammanfattning : Fundamental properties of cloud computing such as resource sharing and on-demand self-servicing is driving a growing adoption of the cloud for hosting both legacy and new application services. A consequence of this growth is that the increasing scale and complexity of the underlying cloud infrastructure as well as the fluctuating service workloads is inducing performance incidents at a higher frequency than ever before with far-reaching impact on revenue, reliability, and reputation.

7. 5. Managing Resource Usage and Allocations in Multi-Cluster Clouds

   Författare :Ewnetu Bayuh Lakew; Erik Elmroth; Francisco Hernandez; Rolf Stadler; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datalogi;

   Sammanfattning :  The emergence of large-scale Internet services has fueled a trend toward large-scale systems composed of geographically distributed clusters. Managing resource allocations and resource usage is an important task for such services. LÄS MER
