-+ Hadoop (computation system):
- + Many individual connected computers behave as one big
- computer. System is horizontally linearly scalable.
- + Programming abstraction and execution model that naturally divides
- problems te be solved in parallel and result easily combined.
- + Data is spread across nodes, automatic failover, built in
- resiliency.
- + Small pieces of code are automatically transferred to the node
- that contains relatively big data that needs processing (network
- efficiency).
