Inside DigitalOcean's Reserved IP Rails migration | DigitalOcean

Reserved IPs (formerly named Floating IPs) is one of our oldest products, and it has changed little since its launch in 2015. As DigitalOcean grew over the years and more customers adopted Reserved IP as a High Availability solution, we started experiencing growing pains, and scaling Reserved IP was critical for continued success. Last year, we were able to prioritize an initiative to overhaul our Reserved IP stack and embarked on a journey that aimed to address various issues for customers and internal teams, ranging from improving the performance and stability of the Reserved IP stack to reducing its maintenance overhead.
