High-available grid services through the use of virtualized clustering

Grid applications comprise several components and web-services that make them highly prone to the occurrence of transient software failures and aging problems. This type of failures often incur in undesired performance levels and unexpected partial crashes. In this paper we present a technique that offers highavailability for Grid services based on concepts like virtualization, clustering and software rejuvenation. To show the effectiveness of our approach, we have conducted some experiments with OGSA-DAI middleware. One of the implementations of OGSA-DAI makes use of Apache Axis
