Whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

Jason Hoffman of JoyEnt on building for Scalabil Ity (at z2007-10-01- Nyc Startup Camp)

(expect to spend 10% of your revenue on operational costs: he's definitely including Managed Hosting and Band Width, but does that also include Sys Admin labor? Dev team?)
leverage DNS
- put static content under separate host-name/sub-domain
  - eventually you might outsource this to CDN, or Amazon S3
  - plan from the start for a hash-driven File System (think I have the label wrong - is Big Table similar idea?), to avoid having more than 10k children of any node
each layer you add to your Infra Structure should provide 10x leverage of the layer below
- ApaChe reverse-Caching Proxy Server fails that test.
uses 2 caches:
- in front of your Application Server: VarNish
- between the app-server and the Data Base:
  - Mem Cached
  - Object Data Base?
  - probable end-game: in-memory Data Store, just stream to RDBMS for BackUp
avoid state (Shared Nothing): stuff all session data into Web Cookie
