Intuit, through its flagship product TurboTax, manages an incredibly high volume of data and disparate data sets during tax season: roughly 400 billion requests with zero downtime.

When Intuit began its migration to the public cloud, three technical challenges had to be addressed: Move Intuit’s tax persistence store running on 20+ Apache Cassandra clusters across multiple namespaces to the cloud, maintain zero downtime during the tax season and maintain a fallback option to Intuit’s private data centers

As the team solved for these three challenges, Cassandra proved to be a valuable asset during this journey and a measurable improvement (from 100% manual to 100% automated) in Cassandra automation was achieved. In this talk, we will share our learnings, our automation journey, and how we managed to solve for availability, speed of migration, and fallback.
