Replication, atomicity and order in distributed systems
http://afeinberg.github.io/2011/06/17/replication-atomicity-and-order-in-distributed-systems.html
Replication, atomicity and order in distributed systems. Distributed systems are an increasingly important topic in Computer Science. The difficulty and immediate applicability of this topic is what makes distributed systems rewarding to study and build. Leaving a Newtonian universe. For the most part, a single machine is a Newtonian universe: that is, we have a single frame of reference. As a result, we can impose a total. Order on events i.e., we can. Are best obtained using multiple machines. Miss...
