This document discusses different solutions for collecting, aggregating, and analyzing tracking event data from websites. It describes problems with an initial solution that collected data on a local server, including network bottlenecks and lack of scalability. Two alternative solutions are proposed: 1) distributing data collection to Akamai and aggregating to Azure, but this had issues with reporting speed and flexibility, and 2) using a third-party solution. The third-party solution, Snowplow, is ultimately selected as it meets requirements for handling different tracker types, unlimited data collection, fast reporting, data ownership, and flexibility. Challenges encountered include data errors, lack of auto-scaling, database query optimization, and over-reliance on visualization
