What does Web tier do?

The "Web tier" in a software architecture typically refers to the layer responsible for handling the presentation and user interface aspects of a web-based application. In the context of Oracle software, specifically Oracle E-Business Suite (EBS), the Web tier plays a crucial role in facilitating user interaction. Here's what the Web tier generally does: User Interface (UI): The Web tier manages the presentation layer and provides the user interface through web browsers. It is responsible for rendering the application's pages and handling user interactions, such as form submissions and button clicks. Communication: The Web tier acts as an intermediary between the user's browser and the application server. It handles user requests, processes them, and communicates with the application tier to retrieve or update data. Load Balancing: In situations where there are multiple web servers, the Web tier often incorporates load balancing mechanisms. This ensures that user requests are distributed evenly across the available web servers, optimizing performance and preventing server overload. Security: The Web tier may implement security measures, such as authentication and authorization, to ensure that users have the appropriate access rights. It helps protect the application from unauthorized access and potential security threats. Caching: To improve performance, the Web tier may implement caching strategies. This involves storing frequently accessed data or web pages locally to reduce the need for repeated requests to the application or database tiers. In summary, the Web tier in Oracle E-Business Suite and similar architectures handles the user interface, communication with the application tier, load balancing, security measures, and caching to deliver a responsive and secure web-based application experience.
