Web application architecture sets the foundation for all of the development work. Get it right and you will benefit from improved scalability, enhanced security, better performance, easier maintenance, and increased flexibility. Get it wrong and you’ll be suffering the consequences long after the software launches. But designing the right web app architecture isn’t easy, especially when you’re part of the 70% of organizations that manage five different application architectures at once! That’s why we are providing a complete guide to web application architecture along with sample architecture diagrams to help you design an architecture that best addresses the needs of your web app. What is web application architecture? Why is web app architecture important? A web application, or web app, is software built using technologies such as HTML, JavaScript, and CSS. They are typically accessed via a web browser and can be used to perform a wide range of tasks, from shopping and banking to streaming media and managing finances. It’s important to understand that a web app is not a website.
While the line might appear blurry, they are, in fact, different. Web apps and websites have different uses, user needs, and expectations. Websites are typically designed to provide users information or accept basic inputs from users. Web applications, on the other hand, are designed to be more interactive and dynamic. What is web application architecture? Now that we know what a web app is, let’s talk more specifically about web application architecture. Essentially web app architecture is how a web app’s components are constructed and connected to each other. Presentation layer: This is the user interface of the web application. It is responsible for the visual aspects of the web application, such as the design of the user interface, the layout of the screens, and the navigation. Application layer: This is the business logic layer. It is responsible for the logic and processes that the web application needs to perform.
This includes the processing of user input, data manipulation, and the execution of business rules. One or multiple web servers live within the application layer. Data layer: This layer is responsible for the persistent data storage and the retrieval of data when needed. It is typically composed of a database and other data stores such as files and web services. It’s worth noting that the data layer could have one or multiple databases, depending on the exact architecture. The 3-tier structure is important because it helps to separate the different elements of a software application. By separating these components, the application can be designed to be more efficient and secure. It also makes it easier to maintain and extend over time. Why is web app architecture important? It’s important to focus on getting the web application architecture right before any web development begins. Doing so will help to ensure that your web app is set up to provide a great experience for the end user and meet the demands of the business today, as well as for the future.
Scalable: Every web app should be designed to accommodate changes in traffic and user needs over time. A well-designed web application architecture will ensure such changes in capacity are handled appropriately with no degradation in performance or reliability. SEO-optimized: A well-designed web application architecture can help with SEO by optimizing the structure of the website to ensure that search engine crawlers can easily access and index the content as well as help ensure that the website is loading quickly,which can help improve overall rankings and visibility. Secure: A well-designed architecture will keep web application components isolated from each other, helping to reduce the attack surface as well as help to protect data by providing secure authentication and authorization mechanisms. On the flip side, if you don't take the time to build a good web app architecture, you may run into a lot of problems down the line. Without a solid architecture, your web application may have difficulty scaling, have poor performance, and be difficult to maintain.
