Monolith to microservices transformation at Broadridge Advisor Solutions
summary
Broadridge breaks a monolithic .NET stack into a microservice platform using AWS services—Cognito for app auth, API Gateway, S3 + CloudFront + Lambda@Edge for delivery, Amazon Aurora for metadata, Amazon Elasticsearch for search, and AWS Fargate / Amazon ECS (chosen over heavy Lambda use) for core services; Amazon Textract and Comprehend automate text processing. A reusable video ingest and index service ships in ~4 months (Dec→Apr) and powers search/retrieval (metadata in Aurora/ES, content in S3), proving the strangler approach and reusable migration-factory patterns work.
