The Financial Times content platform team put its first containers live in mid-2015 and migrated the rest of its services over by April 2016. At that point, the team was using a largely self-built stack on CoreOS Container Linux with Fleet to do cluster management. At the end of 2016, the team members decided they wanted to benefit from the work other people were doing and switched over to Kubernetes. But it’s not easy to do that kind of move when you have 150+ microservices and you need to keep the existing platform running in parallel while you do the migration. Sarah Wells explains why the team decided to do this migration, the challenges they faced in doing it while supporting their live platform, and the lessons learned along the way.
