Indeed, the new publisher is multithreaded and multiprocess. Multiple instances of the modules can run on different machines to ensure high performance and high availability, and this will be true both for the interface modules of the services and the back end data access ones. The system uses message passing to let its components communicate through an AMQP message broker that can itself be distributed to provide better scalability and availability.ELETTRONICOenConference paper10.1117/12.22326862-s2.0-85006507410000388804600074https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9913/1/A-distributed-infrastructure-for-publishing-VO-services-an-implementation/10.1117/12.2232686.short?SSO=12016SPIE.9913E..28CFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE6 Computer Science and Informatics: Informatics and information systems, computer science, scientific computing, intelligent systems::PE6_10 Web and information systems, database systems, information retrieval and digital libraries, data fusion
