coral p2p

from wikipedia

The Coral Content Distribution Network, sometimes called Coral Cache or Coral for short, is a free peer-to-peer content distribution network designed to mirror web content. Coral uses the bandwidth of volunteers to avoid slashdotting and to reduce the load on websites and other web content providers in general. This leverages the bandwidth of the participating Coral nodes as proxy servers, so it is similar to a distributed web proxy.

CAP theorem

from Eric Brewer "invariant boundary"

CAP theorem (consistency, availability, and tolerance of network partitioning, among which at most two can be satisfied at the same time)

ACID v.s. BASE
ACID: atomic, consistency, isolation, and durability
BASE: basically available, soft-state, and eventual consistency
