Discovering Latency with Google Cloud Trace
Latency is one of Google Cloud's Four Golden Signals when it comes to Service Level Indicators – and it's easy to see why. When an application suffers from increased latency, the user experience is a highly negative one: suddenly what was regarded as a reliable application becomes, at best, suspect and, at worst, dismissed as unreliable. Google Cloud's Cloud Trace makes it possible for developers and SREs to keep a close eye on latency analytics. In this hands-on lab, you'll create the infrastructure for the app and then trigger it so you can see how Cloud Trace works, first-hand.
