Faster, Cheaper, Greener: Pick Three
summary
FundApps rearchitects a self‑hosted monolith into a cloud‑native, share‑nothing system on AWS, replacing Windows boxes and a single SQL cluster with Step Functions, SQS, S3, DynamoDB, Lambda, ECS/Fargate and Aurora Serverless v2. The rule engine partitions tens of millions of positions into per‑portfolio jobs (about 20 million rule evaluations) and runs 50–300 Fargate containers per client; 90% of clients migrate successfully, one large bank’s runtime drops from 1h40 to 39m, storage cost falls ~70% storage cost reduction, and a carbon‑neutral-by‑2027 commitment follows.
