Wrap Scientific Applications as WSRF Grid Services Using gRAVI

Abstract

Web service models are increasingly being used in the Grid community as way to create distributed applications exposing data and/or applications through self describing interfaces. Scientific research is one key field in which the benefits are apparent as individual services can be orchestrated into experimental workflows that model the research process and facilitate verification and extension. However, many applications are not web enabled and the task of creating services from scratch is cumbersome in part due to the range of complex technologies, tools, standards and languages involved. In this paper we present gRAVI, a WSRF Web service wrapping tool that allows scientists to rapidly expose applications, scripts and workflows as Web services. gRAVI generated services include GSI security, Grid scheduling, state notifications, persistence and data staging. All service code, scripts and definition files are created automatically without any developer input. gRAVI services are created in standard Grid Archive files and are able to be moved and deployed to any compliant container with no requirement for any gRAVI or Grid infrastructure on the target machine. gRAVI supports deployment to the open science cloud Nimbus, whilst also being able to parse Taverna workflow definition files to create strongly typed services.

Social Cloud: Cloud Computing in Social Networks

“…In particular gRAVI (Grid Remote Application Virtualization Interface) [15] was used to create a base storage service, SORMA [16] is used to create WSAgreements, and DRIVE (Distributed Resource Infrastructure for a Virtual Economy) [17] provides the auction framework.…”

Implementing public health analytical services: Grid enabling of MetaMap

“…To create the MetaMap grid service we used Introduce [34] and Grid Rapid Application Virtualization Interface (gRAVI) [35] which were developed by the caGrid project team. Introduce is an extensible toolkit which supports the development and deployment of WS/WSRF compliant grid services; this toolkit has many plug-ins to aid with development of different services.…”

Scalable and Resilient Workflow Executions on Production Distributed Computing Infrastructures

“…Some initiatives like GASW [11] or LONI Pipeline [12] propose tools to reuse scientific applications on DCIs but they have scalability limitations or interoperability constraints respectively. Concerning Web service-related projects, tools such as GEMLCA [13], and gRAVI [14] manage services lifecycle at different levels, enabling dynamic deployment and/or supporting of nonfunctional concerns. However, their adoption involves the use of an homogeneous middleware.…”
