▁world . ▁One ▁such ▁project ▁that ▁will ▁benefit ▁from ▁this ▁topology ▁would ▁be ▁C ER N ▁that ▁runs ▁the ▁Lar ge ▁Had ron ▁Coll ider ▁that ▁generates ▁enorm ous ▁amounts ▁of ▁data . ▁This ▁data ▁is ▁located ▁at ▁one ▁source ▁and ▁needs ▁to ▁be ▁distributed ▁around ▁the ▁world ▁to ▁organizations ▁that ▁are ▁collabor ating ▁in ▁the ▁project . ▁ ▁Hy brid ▁Top ology ▁is ▁simply ▁a ▁configuration ▁that ▁contains ▁an ▁architecture ▁consisting ▁of ▁any ▁combination ▁of ▁the ▁previous ▁mentioned ▁top ologies . ▁It ▁is ▁used ▁mostly ▁in ▁situations ▁where ▁research ers ▁working ▁on ▁projects ▁want ▁to ▁share ▁their ▁results ▁to ▁further ▁research ▁by ▁making ▁it ▁readily ▁available ▁for ▁collaboration . ▁ ▁History ▁The ▁need ▁for ▁data ▁gr ids ▁was ▁first ▁recognized ▁by ▁the ▁scientific ▁community ▁concerning ▁climate ▁model ing , ▁where ▁ter aby te ▁and ▁pet aby te ▁s ized ▁data ▁sets ▁were ▁becoming ▁the ▁norm ▁for ▁transport ▁between ▁sites . ▁More ▁recent ▁research ▁requirements ▁for ▁data ▁gr ids ▁have ▁been ▁driven ▁by ▁the ▁Lar ge ▁Had ron ▁Coll ider ▁( L HC ) ▁at ▁C ER N , ▁the ▁Las er ▁Inter fer ometer ▁Gra v it ational ▁W ave ▁Observ atory ▁( LI GO ), ▁and ▁the ▁Slo an ▁Digital ▁Sky ▁Survey ▁( SD SS ). ▁These ▁examples ▁of ▁scientific ▁instruments ▁produce ▁large ▁amounts ▁of ▁data ▁that ▁need ▁to ▁be ▁accessible ▁by ▁large ▁groups ▁of ▁ge ograph ically ▁dispers ed ▁research ers . ▁Other ▁uses ▁for ▁data ▁gr ids ▁involve ▁govern ments , ▁hosp it als , ▁schools ▁and ▁business es
