About This Architecture

Multi-cloud architecture connecting end users through the internet to a centralized application tier backed by a persistent database layer. Data flows from users via internet connectivity to the application, which queries and persists information in the database. This foundational pattern demonstrates separation of concerns and scalability principles essential for cloud-native systems. Fork this diagram on Diagrams.so to customize for your specific cloud provider, add load balancers, or extend with caching and CDN layers. Consider adding API gateways and authentication services for production deployments.
