Abstract: Methods, systems, and computer-readable media for providing collaborative quality of service (“QoS”) for service-oriented architectures are described. The application services in the service-oriented architecture implement a QoS application-programming interface (“API”) in addition to the traditional service API. The QoS API may include a QoS reporting interface for reporting values of QoS metrics of the application service, a QoS mechanism interface that exposes details of dependability mechanisms utilized by the application service, and/or a QoS negotiation interface that allows dynamic negotiation of what QoS properties the application service provides and how the QoS properties are provided. Service consumers may utilize the QoS API of the various application services in the service-oriented architecture to collect dependability information regarding the application services and make service provider selection decisions during discovery and dynamic binding.

Abstract: The present disclosure relates to dynamically allocating multitier applications based upon performance and reliability of resources. A controller analyzes resources and applications hosted by the resources, and collects operational data relating to the applications and resources. The controller is configured to determine an allocation scheme for allocating or reallocating the applications upon failure of a resource and/or upon rollout or distribution of a new application. The controller generates configuration data that describes steps for implementing the allocation scheme. The resources are monitored, in some embodiments, by monitoring devices. The monitoring devices collect and report the operational information and generate alarms if resources fail.

Abstract: Disclosed is an approach to system call monitoring in which authenticated system calls from an application are easily verified by an operating system kernel. The authenticated system call may be a system call augmented with extra arguments, which specify the policy for that call as well as a cryptographic message authentication code (MAC) that guarantees the integrity of the policy and the system call arguments. This extra information is used by the operating system kernel to verify the system call with little processing overhead. Versions of the applications in which regular system calls have been replaced by authenticated calls are generated automatically by a trusted installer program that reads the application binary, uses static analysis to generate policies, and then rewrites the binary with the authenticated calls. As a result, hacker attacks, malicious software and the like are less likely to be successful in compromising any computers or networks that employ such authenticated system calls.
