In this lecture, we consider the problem of replicating data across geo-distributed locations, a problem that is increasingly relevant for large data center applications. We cover several solutions based on the type of operation that the storage system must provide and on the whether replicas must be updated immediately or eventually. For each solution, we consider the trade-offs that it offers in terms of consistency and performance.
