Towards QoS Prediction Based on Composition Structure Analysis and Probabilistic Models
The quality of service (QoS) of complex software systems, built by composing many components, is essential to determine their usability. Since the QoS of each component usually has some degree of uncertainty, ...

Transforming Service Compositions into Cloud-Friendly Actor Networks
While conversion of atomic and back-end services from centralized servers to cloud platforms has been largely successful, the composition layer, which gives the service-oriented architecture its flexibility an...

A Constraint-Based Approach to Quality Assurance in Service Choreographies
The knowledge about the quality characteristics (QoS) of service compositions is crucial for determining their usability and economic value; the quality of service compositions is usually regulated using Servi...

Constraint-Based Runtime Prediction of SLA Violations in Service Orchestrations
Service compositions put together loosely-coupled component services to perform more complex, higher level, or cross-organizational tasks in a platform-independent manner. Quality-of-Service (QoS) properties, ...

A Soft Constraint-Based Approach to QoS-Aware Service Selection
Service-based systems should be able to dynamically seek replacements for faulty or underperforming services, thus performing self-healing. It may however be the case that available services do not match all r...

Automatic Fragment Identification in Workflows Based on Sharing Analysis
In Service-Oriented Computing (SOC), fragmentation and merging of workflows are motivated by a number of concerns, among which we can cite design issues, performance, and privacy. Fragmentation emphasizes the ...

An Initial Proposal for Data-Aware Resource Analysis of Orchestrations with Applications to Predictive Monitoring
Several activities in service oriented computing can benefit from knowing ahead of time future properties of a given service composition. In this paper we focus on how statically inferred computational cost fu...
