Planning a petabyte-scale cloud migration with zero customer impact sounds daunting — and Salesloft's VP of Infrastructure Clari/Salesloft did it in three months. Balaji Narayanan breaks down the planning discipline, pre-mortem process, and cutover strategy his team used to migrate 110 databases across three regions to Google Cloud without a single customer feeling it.

This conversation covers how Balaji's team categorized every migration step as a one-way or two-way door decision, why he insists on testing the full procedure in a replicated environment before the real cutover, and how global round-the-clock coverage across India, South Africa, and the U.S. kept the project on track. This episode kicks off a three-part series on building the infrastructure foundation that makes everything else possible.
