The client layer can be a thin-client which means hardware costs are reduced. For that reason, a change of management is easy and cost-effective. Data integrity is improved as all data goes through the application server which decides how data should be accessed and by whom. You can abstract the core business from the database server to efficiently perform load balancing. You can scale it horizontally by scaling each item independently. The ability to deploy application servers on multiple machines provides higher scalability, better performance, and better re-use. The 3-tier architecture is more secure as the client does not directly access the data. The communication between the client and the database is managed by the intermediate application layer thereby enabling clients to access data from different DBMS solutions. In this model, the intermediate servers receive client requests and process them by coordinating with subordinate servers applying the business logic. When it comes to 3-tier architecture, there are three layers: Railway reservation systems and content management systems are a couple of applications that are usually built using this architecture. Moreover, the direct interaction of the database and the user device also raises some security concerns. The downside of 2-tier architecture is that with an increased number of users, the performance decreases.

Here the business logic is incorporated into the user interface or the database server.

In a traditional 2-tier architecture, there are two components namely the client side system or the user interface and a backend system which is usually a database server. In a multi-tiered architecture, database servers can manage business logic with the help of stored procedures. It can run and oversee requests from a wide variety of clients.ģ) Database Server: The database server provides the required data for the application.

User inputs are validated as well, if required.Ģ) Web Server: The web server also known as the backend component or the server-side component handles the business logic and processes the user requests by routing the requests to the right component and managing the entire application operations. Typically a web-based application architecture comprises of three core components:ġ) Web Browser: The browser or the client-side component or the front-end component is the key component that interacts with the user, receives the input, and manages the presentation logic while controlling user interactions with the application. As such, it is important to understand the components comprising the architecture of web apps. Choosing the right design defines your company growth, reliability and interoperability and future IT needs. It creates and manages records while providing permission-based access and authentication. Moreover, it also secures that valid data is present in all user requests. It defines how the data is delivered through HTTP and ensures that the client-side server and the backend server can understand.

An Overview of Web Application ArchitectureĪ web app architecture presents a layout with all the software components (such as databases, applications and middleware) and how they interact with each other. In this article, you’ll discover what a web app architecture is, how a web application architecture diagram looks, and how you can design the right architecture for web apps. Have you ever wondered how computers retrieve this information and what happens in the background? It’s an underlying web application architecture that makes this process possible. When a user logs on to a desktop/laptop or a mobile, opens a browser, and types the name of a website, the browser displays the required information and the user performs an action on the site.
