- Level 0: no redundancy
- Level 1: support manual failure detection & rerouting or recovery within a single site; tested to complete in 30 minutes
- Level 2: support automated failure detection & rerouting
- within a single geographic site
- stateless components: establish baseline measure of failed requests for a component failure within a site
- stateful components: establish baseline of data loss for a component failure within a site
