Example text

For instance, a family contains several genus, and a genus contains several species. A query accessing all the species of a given genus (or family) allows to define a genus-wide (resp. family-wide) partition. Once the partition is defined, we decide which resource to allocate to each partition, using a data placement strategy. Several partitions may reside at the same machine Green and Distributed Architecture for Managing Big Data of Biodiversity 33 as long as the corresponding workload does not exceed the machine capacity.

The work carried out by experts from these different organizations frequently result in the production and the exploitation of large amount of data. However, the management and the use of this critical amount of data are far from being satisfactory. The main reason is related to the nature of the data which are often voluminous, distributed, heterogeneous, and confidential. Furthermore, another major constraint is related to the increasing evolution of data due to hydro-climatic hazards, desertification, and permanent changes in the socioeconomic layout of the region.

2 Drawback of a Static-Based Resources Allocation In fact, for most of the analysis done over the data biodiversity, a user has to download occurrences of species that are required for a given study. In addition, climatic and environmental data may also be required for a purpose of a study. In such a case, data have to be gathered or integrated through aggregation and join queries that are very expensive, mainly, for large partition of data. That is, the amount of data used in the management of biodiversity are tied to a heavy workload because of the number of potential users.
