Taming the FinTech Beast
summary
A large UK financial advice platform evolves from a monolith into a cloud-native ecosystem over several multi-year phases, extracting about 20 initial microservices and growing to 80+ microservices and micro-frontends orchestrated on AWS with EKS + Kubernetes + Windows nodes and managed services (SQS, SNS, S3, Elasticache, SQL Server on EC2). The team migrates .NET Framework to .NET Core, introduces CI/CD, React micro-frontends with Luigi, and a BFF layer; surprises include severe deadlocks from DB-level integrations and much higher integration and testing overhead than estimated.
