QoS issues in Web services
TLDR
QoS measures can include the maximum throughput or a function that describes how throughput varies with load intensity, which can be measured in terms of arrival rates (such as requests per second) or number of concurrent requests.Abstract:
Quality of service (QoS) is a combination of several qualities or properties of a service, such as: availability is the percentage of time that a service is operating; security properties include the existence and type of authentication mechanisms the service offers, confidentiality and data integrity of messages exchanged, nonrepudiation of requests or messages, and resilience to denial-of-service attacks; response time is the time a service takes to respond to various types of requests; Response time is a function of load intensity, which can be measured in terms of arrival rates (such as requests per second) or number of concurrent requests. QoS takes into account not only the average response time, but also the percentile of the response time; and throughput is the rate at which a service can process requests. QoS measures can include the maximum throughput or a function that describes how throughput varies with load intensity. The QoS measure is observed by Web services users. These users are not human beings but programs that send requests for services to Web service providers. QoS issues in Web services have to be evaluated from the perspective of the providers of Web services and from the perspective of the users of these services.read more

Adding meaning to qos negotiation
TL;DR: A Service Level Agreement (SLA) ontology that explicitly considers subjective user QoS specification was conceived, and its internal components and the role it plays during service discovery are outlined.
Elastic cloud storage control for non-uniform workloads
TL;DR: This work investigates partition-demand aware control, demonstrating experimentally that this information can be turned to control able to consider the structure of the workload it is observing, rather than assuming it evenly distributed across the keyspace.
Evaluating Efficiency Quality Attribute in Open Source Web browsers
TL;DR: The main objective of conducting this research is to formulate EBC guidelines, which can be later used by OSS developers to test their web browsers and ensure that all the quality standards are strictly adhered during the development of OSS products.

Session-based admission control: a mechanism for peak load management of commercial Web sites
Ludmila Cherkasova,P. Phaal +1 more
TL;DR: It is shown that a Web server augmented with the admission control mechanism is able to provide a fair guarantee of completion, for any accepted session, independent of a session length, which is a critical requirement for any e-business.
