This is a UML deployment diagram for an online web application. It illustrates a multi-layered web architecture, showcasing the network and server components required for deploying a web application. The diagram includes a client browser, load balancer, two web servers (handling application components), two application servers (processing business logic), and a database server (storing data). Each server interacts through specific protocols, with HTTP/HTTPS between the client and load balancer, and SQL queries between the application and database servers, ensuring efficient data flow and load distribution.
