Defining Platform Research Infrastructure as a Service (PRIaaS) for Future Scientific Data Infrastructure

Abstract Modern science increasingly works with large amount of data, which are heterogeneous, are distributed, and require special infrastructure for data collection, storage, processing, and visualization. Science digitalization, likewise industry digitalization, is facilitated by the explosive development of digital technologies and cloud-based infrastructure technologies and services. This paper attempts to understand impact and new requirements to the future Scientific Data Infrastructure imposed by growing science digitalization. The paper presents two lines of analysis: one is a retrospective analysis related to the European Research Infrastructure (RI) development stages and timeline from centralized to distributed and current Federated Interoperable; another line provided analysis of digital technology trends and identified what technologies will impact the future Scientific Data Infrastructure (SDI). Based on this analysis, the paper proposes a vision for the future RI Platform as a Service (PRIaaS) that incorporates recent digital technologies and enables platform and ecosystem model for future science. Notably the proposed PRIaaS adopts TMForum Digital Platform Reference Architecture (DPRA) that will simplify building and federating domain-specific RIs while focusing on the domain-specific data value chain with data protection and policy-based management by design.
