Exemples, applications, utilisations

Benefits and Challenges • Performance • Scalability • Redundancy (for fault-tolerance) • How to ensure consistency among nodes of a distributed system? • Even if some aren’t reliable nor honest? • Trust without trust? • Requires a way to reach “consensus” Example: Database Systems • For a centralized database system, one central entity handles all requests and data processing • Data updates simple and quick • Cheaper to manage and maintain • Performance bottleneck under high concurrent requests • Single point of failure (+)
