CASC stands for Cloud API Service Consistency – APImetrics realized early on that there are lots of ways to measure API performance – availability, uptime, pass rate, latency but all of these go into the quality of your runtime solution, including how it works for the end user from where the application is based.
We took these, and taking advantage of our database – the largest in the world of real API call performance to identify the issues that really impacted API users. Key to the experience was consistency. An API can be slow but you can build for that. You can’t build for inconsistent service and that’s what the score detects and warns
