We are a 24-hour online business. We use it for scheduling our on-call engineers and making sure that there is follow-the-sun or round-the-clock coverage for alerting and network operations.
It ingests all our alert paths, i.e., anything that generates an alert of any description, such as, Splunk, AWS, and internal applications. We feed all our events into it, then it generates alerts which need a response from an engineer with a description. Another thing is it is built-in scheduling is pretty much hands-off for our on-call engineers unless somebody goes on holidays. That is the only time that we have to jump in there and make any changes.
