But in order to do that, it needs to be setup properly, measured and shared with others. On this DevCentral Connects, Buu Lam is joined by Ryan MacLean, Developer Advocate with Datadog. Ryan is going to share the acronyms "LETS USE RED" and how to make monitoring for everyone!

In this kick-off episode of The Drift, Jason weighs in on the options presented in the DevCentral forums regarding alerting on system failovers.
