Learning objectives
- 01Describe the effect of a network partition on a replicated system
- 02Place a given system on the consistency/availability trade-off
- 03Explain why no reliable global clock exists
Guided lab
Induce a partition between three containerised replicas and watch the states diverge.
Independent lab
Design, document and test a post-partition reconciliation strategy.
Security angle
How an attacker manufactures a partition, and why node eclipsing follows from it.
Assessment
Experiment write-up describing the observed divergence and its cause.
