By comparing with Paxos, we understand the core ideas of raft and Zab and deepen the understanding of conformance agreements. 9–10) This is a commentary to: Optimum Design of Rotating Disks US$ 39.95. No prerequisites beyond basic familiarity with mathematical reasoning are required; prior knowledge on asymptotic notation and (occasionally) standard probabilistic notions can be useful, but is not essential for following the course. We study algorithms and lower bounds for typical problems that arise in distributed systems---like resource allocation, implementing shared memory abstractions, and reliable communication.
