Explore a 15-minute conference talk from USENIX NSDI '23 that delves into NetPanel, a traffic measurement platform for Microsoft's Exchange Online (EXO) service. Learn how this innovative system fuses IPFIX, Event Tracing for Windows (ETW), and application logs to measure service traffic at the component level. Discover the challenges of identifying traffic contributors in global cloud applications and how NetPanel addresses these issues with cost-effective, component-level measurements under strict resource restrictions. Gain insights into NetPanel's operational success, including its role in profiling network traffic characteristics and traffic cost composition of EXO, resulting in millions of dollars saved in network resources. Understand the platform's efficiency, requiring less than 1% CPU and disk I/O on production servers and minimal computational resources for data processing.
