The cloud-hosted version would need to be: Scalable – The service would need to support hundreds of thousands, or even millions of AWS customers, each supporting their own internet-scale applications. Today, DynamoDB powers the next wave of high-performance, internet-scale applications that would overburden traditional relational databases.

In the end, it’s not the load events or server response times that define the experience, but the perception of how snappy the interface feels. Custom metrics measure a particular, custom event for the user, e.g. Twitter’s Time To First Tweet and Pinterest’s PinnerWaitTime. What does it mean? First Input Delay ( FID ) < 100ms.

Here's some output from my zfsdist tool, in bcc/BPF, which measures ZFS latency as a histogram on Linux: # zfsdist. Tracing ZFS operation latency. The odd time we hit them, we'll take the "oops message" – a dump of the kernel stack trace and other details from the system log – and search the Internet. x series.

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. It enables customers to run their Redis nodes at higher memory utilization without risking swap usage during events such as snapshotting and replica synchronization.
