Self-Adaptive Utility-Based Web Session Management
"... In the Internet, where millions of users are a click away from your site, being able to dynamically classify the workload in real time, and predict its short term behavior, is crucial for proper self-management and business efficiency. As workloads vary significantly according to current time of day ..."

Policydriven Middleware for Self-Adaptation of Web Service Compositions
- In Proc. of the 7th International Middleware Conference (Middleware), volume 4290 of LNCS
, 2006
"... Abstract. We present our policy-based middleware, called Manageable and Adaptive Service Compositions (MASC), for dynamic self-adaptation of Web services compositions to various changes. MASC integrates and extends our earlier middleware called the Web Services Message Bus (wsBus). In particular, we ..."

Self-adaptive and self-configured CPU resource provisioning for virtualized servers using Kalman filters
- in 2009 ICAC
"... Data center virtualization allows cost-effective server consol-idation which can increase system throughput and reduce power consumption. Resource management of virtualized servers is an important and challenging task, especially when dealing with fluctuating workloads and complex multi-tier server ..."

and self-adapt to unforeseen workload intensity changes. Our more advanced controller self-configures itself to any workload condition without any a priori information. In-dicatively, it results in within 4.8 % of the performance of workload-aware controllers under high intensity workload changes
Distributed stream management using utility-driven self-adaptive middleware
- In Proceedings of 2nd International Conference on Autonomic Computing (ICAC’05
, 2005
"... We consider pervasive computing applications that process and aggregate data-streams emanating from highly distributed data sources to produce a stream of updates that have an implicit business-value. Middleware that enables such aggregation of datastreams must support scalable and efficient selfman ..."

In this paper, we present a novel self-adaptation algorithm that has been designed to scale efficiently for thousands of streams and aims to maximize the overall business utility attained from running
Self-Adaptive and Self-Congured CPU Resource Provisioning for Virtualized Servers Using Kalman Filters

to virtual machines hosting server applications. The novelty of our approach is the use of the Kalman lter|the optimal ltering technique for state estimation in the sum of squares sense|to track the CPU utilizations and update the allocations accordingly. Our basic controllers continuously detect and self-adapt
S.: Characterizing problems for realizing policies in self-adaptive and self-managing systems
- In: Proceedings of the 6th ACM/IEEE International Symposium on Software Engineering for Adaptive and Self-Managing Systems (SEAMS 2011

Session-based admission control: A mechanism for peak load management of commercial web sites
- IEEE Transactions on Computers
"... AbstractÐIn this paper, we consider a new, session-based workload for measuring web server performance. We define a session as a sequence of client's individual requests. Using a simulation model, we show that an overloaded web server can experience a severe loss of throughput measured as a num ..."

Self-adaptation of Fault Tolerance Requirements using Contracts
"... Fault tolerance is a constant concern in data centers where servers have to run with a minimal level of failures. Changes on the operating conditions or on server demands, and variations of the systems own failure rate have to be handled in such a way that SLAs are honored and services are not inter ..."

We present an approach to handle fault tolerance requirements, based on component replication, which is supported by a context-aware infrastructure and guided by contracts that describe adaptation policies for each application. At run-time the infrastructure autonomically manages the deployment
SPATIAL KNOWLEDGE MANAGEMENT SYSTEM FRAMEWORK THROUGH SELF-ADAPTIVE MODELING
