There is a famous Cassandra PPT at SigMod 2008. In one slide, they presented several interesting lessons:

  1. Add fancy features only when absolutely required
  2. Many types of failures are possible
  3. Big systems need proper system-level monitoring
  4. Value simple designs

These lessons are interestingly useful. :-)
