Manish Sharma discusses Fair Isaac Corporation's migration of its myFICO consumer website to AWS. Key reasons for migrating included improving reliability by solving for multiple points of failure and improving security. The migration took 7 months and involved "lift and shift" of applications along with upgrades.
