A Standard for Cloud API Performance Measurement

Introduction to Cloud API Service Consistency (CASC) Scoring

CASC, or Cloud API Service Consistency, is a score out of 10 that describes how consistently a cloud API performs. This white paper from APImetrics introduces the standard, how the score is calculated, and how to read it. Read the full text on this page, or complete the form to receive the PDF.

• How a CASC score combines latency, consistency and sample depth
• What each of the three CASC score zones means for an API
• Why comparing APIs requires the same measurement method
• What an unhealthy API can cost the business
