Presentation: Fault Tolerance at Speed

Distributed systems providing fault tolerance often sacrifice performance. The sacrifice often happens late when a systems engineering approach is not taken. Performance is an inherent aspect of distributed design and should be considered holistically in the systems engineering process. A well designed distributed system can be both fault-tolerant and fast.

In this session, we discuss the techniques and lessons learned from implementing the Aeron Cluster. The focus will be on how Raft can be implemented on Aeron, minimizing the network round trip overhead, and comparing a single process to a fully distributed cluster. Come to this session if interested in how performance can be a first-class design concern and the results which can be delivered.
