The EUBra-BIGSEA initiative will address most of the challenges related to the composition of Big Data applications and their deployment on the cloud platform with a specific highlight on security and QoS. The adoption of standards and widely used interfaces will ensure interoperability with existing data frameworks and alignment with the global activities on the development of Big Data architectures.
Through a strong collaboration between Europe and Brazil, EUBra-BIGSEA will propose innovative technologies combining advanced Clouds and Big Data Services to address the challenges stemming from a massively connected societies use case with high social and business relevance. In particular, EUBra- BIGSEA will tackle multiple challenges, dealing with resource provision, performance, QoS for cloud computing infrastructure, security and privacy. This will be achieved via the design of an efficient parallel programming framework and APIs to support different types of data storage, models and end-user applications. The use of standards, TOSCA for Big Data and run-time management of Cloud infrastructures, and OVF and OCCI for software appliances will contribute to support interoperability and data portability issues towards future standardization.
Data management aspects will be addressed using:
(i) interoperable data service interfaces and metadata standards (OGC-WPS/WCS and ISO19115/19139. These are just some examples for geospatial data sources.
(ii) standard data formats/conventions (e.g. NetCDF-CF, HDF5, GRIB etc. for environmental and geospatial data) for the data being used.
Depending on the available set of data, key standards/specifications at different levels (e.g. services, formats, metadata) will be identified and exploited to address data portability and interoperability requirements.
