My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

Three years ago, as part of our AWS Fast Data journey we introduced Amazon ElastiCache for Redis , a fully managed in-memory data store that operates at sub-millisecond latency. This allows for faster failover times while minimizing latency. The client keeps a map of Redis nodes, which is updated in case of failover.

Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms.

For example, the most fundamental abstraction trade-off has always been latency versus throughput. Modern CPUs strongly favor lower latency of operations with clock cycles in the nanoseconds and we have built general purpose software architectures that can exploit these low latencies very well. Where to go from here?

Achieving strict consistency can come at a cost in update or read latency, and may result in lower throughput. Amazon S3 and Amazon SimpleDB are examples of AWS services that are designed using these high-availability principles using an eventual consistency model. Lowest read latency. Higher read latency. No stale reads.
