Amazon's system mainly uses two frameworks: AWS (Amazon Web Services) and SOA (Service-Oriented Architecture). AWS is a global cloud computing platform that provides a series of infrastructure and services, including computing, storage, database, analysis, security, etc., providing Amazon with high availability, flexibility and scalability infrastructure support. SOA is a service-oriented architecture that splits the system into multiple independently deployable and reusable services to achieve loose coupling and high cohesion of the system, thereby improving the maintainability and scalability of the system. The combination of the two frameworks provides Amazon with an efficient and reliable system architecture, supporting its rapid development and innovation.
