This month I want to highlight an Amazon blog, Migration Complete – Amazon’s Consumer Business Just Turned off its Final Oracle Database, by Jeff Barr. This blog discusses how Amazon’s consumer business sunset Oracle over the course of several years, culminating in this announcement two weeks ago. An undertaking of this scale is unprecedented, made possible by the efforts of individuals like you and teams like yours. As we look towards the future and think of how we delight our customers, the Oracle sunset make it clear that nothing is out of reach, no matter how challenging.

“Today I would like to tell you about an internal database migration effort of this type that just wrapped up after several years of work. Over the years we realized that we were spending too much time managing and scaling thousands of legacy Oracle databases. Instead of focusing on high-value differentiated work, our database administrators (DBAs) spent a lot of time simply keeping the lights on while transaction rates climbed and the overall amount of stored data mounted.”
