WebReplication is one of the oldest and most important topics in the overall area of distributed systems. Data replication and computation replication both require processes to handle … WebReplication If your data workload is primarily read-focused, replication increases availability and read performance while avoiding some of the complexity of database sharding. By simply spinning up additional copies of the database, read performance can be increased either through load balancing or through geo-located query routing.

WebThis paper describes a new replication algorithm that is able to tolerate Byzantine faults. We believe that Byzantine-fault-tolerant algorithms will be increasingly important in the future because malicious attacks and software errors are increasingly common and can cause faulty nodes to exhibit arbitrary behavior.
