Over my 17 years at Amazon, I have seen that my colleagues on the engineering team are never content to leave good-enough alone. They routinely re-evaluate every internal system to make sure that it is as scalable, efficient, performant, and secure as possible. When they find an avenue for improvement, they will use what they have learned to thoroughly modernize our architectures and implementations, often going so far as to rip apart existing systems and rebuild them from the ground up if necessary.
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
