The document discusses modernizing applications using AWS services like RDS for PostgreSQL, Amazon MemoryDB, and containers. It describes how applications have evolved from monolith architectures to microservices architectures to improve scalability, performance, and agility. It provides an overview of these AWS services for building microservices architectures, including how they provide scaling, high performance, and agility. It concludes with a demo of using these services to build a sample modern retail website application.
