Big Data: Working Definition
Requirements cannot be met on a single computer
Variety, Volume, Velocity, Variability, Availability
Imprecise terms, but useful for understanding problem space
All relative – what was impossible yesterday is Big Data today and will be trivial tomorrow
Distribute data storage to support volume & velocity
Replicate data storage to provide availability
Distribute processing
Apply compute power in parallel
Avoid moving data across the network – move the answers
