The presentation discusses the migration of 700 clusters to Cluster API for central cluster management and the lessons learned from the process.
  • Cluster API provides central cluster management for the complete life cycle of a cluster.
  • The migration process involved transitioning from a legacy provisioning architecture to Cluster API.
  • Zero downtime was a crucial requirement during the migration process.
  • Testing and bug fixing were important steps in the migration process.
  • The platform is under constant construction with feature improvements and bug fixing.
  • The team plans to implement additional Cluster API features and offer public clouds to users.
  • The migration process took around a year to complete.
