Architecture and Execution Model for a Survivable Workflow Transaction Infrastructure
نویسندگان
چکیده
We present a novel architecture and execution model for an infrastructure supporting fault-tolerant, long-running distributed applications spanning multiple administrative domains. Components for both transaction processing and persistent state are replicated across multiple servers, ensuring that applications continue to function correctly despite arbitrary (Byzantine) failure of a bounded number of servers. We give a formal model of application execution, based on atomic execution steps, linearizability and a separation between data objects and transactions that act on

متن کاملArchitectural Plan for Constructing Fault Tolerable Workflow Engines Based on Grid Service
In this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. The engines are assumed to be implemented as composite web services. Current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. The difficulty is to rollback the execution state of the workflo...

متن کاملA Clustering Approach to Scientific Workflow Scheduling on the Cloud with Deadline and Cost Constraints
One of the main features of High Throughput Computing systems is the availability of high power processing resources. Cloud Computing systems can offer these features through concepts like Pay-Per-Use and Quality of Service (QoS) over the Internet. Many applications in Cloud computing are represented by workflows. Quality of Service is one of the most important challenges in the context of sche...
متن کاملWorkflow Management for Grid Computing - A Grid Workflow Infrastructure
In this paper we propose a Grid Workflow Infrastructure, which serves as the base for specifying and executing collaborative interactive workflows within computational grids. The infrastructure is based on the Open Grid Services Architecture (OGSA) and leverages the concepts of the Business Process Execution Language for Web Services (BPEL4WS). Using OGSA enables us to exploit advanced Grid fea...
