Too Long; Didn't Read
This talk gives an excellent overview of challenges that developers and architects need to overcome to remain viable in a very demanding environment. The presentation dives into several of these groupings, especially replication, and provides the context for different scenarios developers are dealing with. Cross-DataCenter Replication (XDCR) allows clusters to run in multiple geographic regions yet stay up to date. Developers can instead focus on writing applications and just pointing them to use a cluster. They don’t need a deep knowledge of how nodes work or how clusters are maintained.
