A Programmble Fault Injection Testbed Generator for SOA
نویسندگان
چکیده
In this demo paper we present the prototype of our fault injection testbed generator. Our tool empowers engineers to generate emulated SOA environments and to program fault injection behavior on diverse levels: at the network layer, at the execution level, and at the message layer. Engineers can specify the structure of testbeds via scripts, attach fault models, and generate running testbed instances from that. As a result, our tool facilitates the setup of customizable testbeds for evaluating fault-handling mechanisms of SOA-based systems.

Programmable Fault Injection Testbeds for Complex SOA
The modularity of Service-oriented Architectures (SOA) allows to establish complex distributed systems comprising e.g., services, clients, brokers, and workflow engines. A growing complexity, however, automatically increases the number of potential fault sources which have effects on the whole SOA. Fault handling mechanisms must be applied in order to achieve a certain level of robustness. In t...
متن کاملException Analysis in Service-Oriented Architecture
Exception handling is one of the powerful means of achieving high dependability and fault-tolerance in service-oriented architecture (SOA). The paper introduces the results of experimental analysis of the SOA-specific exceptions and factors affecting availability and fault-tolerance of Web Services, implemented by use of different development kits. We discovered several types of failure domains...
متن کاملApplication of Three Physical Fault Injection Techniques to the Experimental Assessment of the MARS Architecture Johan Karlsson
This paper describes and compares three physical fault injection techniques—heavy-ion radiation, pin-level injection, and electromagnetic interference—and their use in the validation of MARS, a fault-tolerant distributed real-time system. The main features of the injection techniques are first summarized, and then the MARS system is described. The distributed testbed setup and the common test s...

متن کاملImproving Dependability in Service Oriented Architectures using Ontologies and Fault Injection
Large distributed systems and computer grids are increasingly being used in science and in business, with Service Oriented Architectures combined with Web services the current favoured solutions to access these distributed, heterogeneous resources. However, service-based systems have a high reliance on a middleware which is continuously evolving. This requires novel methods of testing and evalu...
