How to Build a Highly Scalable Architecture for Push Delivery
summary
Describes Hotmart’s serverless, event-driven push service architecture built with AWS technologies — specifically Kinesis for streaming, Lambda for compute, DynamoDB for storage, and Elasticsearch for indexing — designed for resilience, low latency and predictable cost. Covers the push service responsibilities (device config, unread badge counts, i18n, message history), the challenges of delivery speed and maintaining correct unread counts, and mentions using open-source tools and other managed services to implement the solution.
