Amazon S3 processes millions of requests per second and stores over 350 trillion objects using a microservices architecture. The system consists of five main layers: front-end services for request handling and authentication, metadata services for object indexing, storage services using erasure coding across multiple availability zones, durability services with checksums and auditing, and security services with IAM policies and encryption. This modular approach enables independent scaling and updates while achieving 11 nines of durability.
