Federated Access Control Infrastructure (FACI) that would ensure normal
infrastructure operation and assets and information protection and allow
user authentication and policy enforcement in the distributed multi-
organization environment. The future SDI should support the entire data life
cycle and explore the benefits of data storage/preservation, aggregation, and
provenance on a large scale and during a long or unlimited period of time;
accordingly, the future FACI should support all stages of the data life cycle,
including policy attachment to data to ensure persistency of the data policy
enforcement during continuous online and offline processes.
The required FACI should support the following features of the future SDI:
• Empower researchers (and garner their trust) to do their data pro-
cessing on shared facilities of large data centers with guaranteed
data and information security.
• Motivate/assure researchers that they can share or open their
research environment to other researchers by providing tools for
instantiation of customized preconfigured infrastructures to allow
other researchers to work with existing or their own data sets.
• Protect data policy, ownership, linkage (with other data sets and newly
produced scientific/research data) when providing (long term) data
archiving. Data preservation technologies should themselves ensure
data readability and accessibility with the changing technologies.
2.8 Summary and Future Development
The information presented in this chapter provides a snapshot of the
fast-developing big data and data analytics technologies that merge modern
e-science research methods and experience of dealing with the large-scale
problems, on one hand, and modern industry speed of technology develop-
ment and global scale of implementation and services availability on the
other. At this stage, we summarized and presented rethinking on some
widely used definitions related to big data; further research will require a
more formal approach and taxonomy of the general big data use cases in
both science and industry.
As a part of general infrastructure research, we will continue research on
the infrastructure issues in big data, targeting a more detailed and technol-
ogy-oriented definition of SDI and related security infrastructure definition.
Special attention will be given to defining the whole cycle of the provi-
sioning of SDI services on demand, specifically tailored to support instant
scientific workflows using cloud IaaS and PaaS platforms. This research will
also be supported by development of the corresponding cloud architecture
