In this sea of web apps, if you want yours to truly shine, it's crucial to ensure that your web application architecture is robust like never before. The web app architecture serves as the backbone, defining the intricate relationships between databases, servers, and applications within a system. It's the very foundation upon which your app's seamless user experience and flawless functionality are built.
However, keep in mind that the architecture of an app can vary based on the specific business type and unique requirements. Unfortunately, many companies overlook this fact, but a resilient and modern web app architecture is the secret key to unlocking unrivaled success and boundless profits.
So, let us guide you down the path to unlimited profits and triumphant achievements. All you need to do is dive into this enlightening piece that unravels the world of web app architecture—its components, types, and models.
Now, let's embark on this journey by delving into the basics first.
The web application architecture is a layout or a model of interaction between web application components such as applications, databases, and middleware systems on the web.
It shows the communication happening between all the elements, such as from databases to the server to interfaces. In short, the modern web application architecture indicates the logic behind server requests and responses to clients.
Perhaps a diagram of the architecture can help you understand the whole concept better.
Suppose you are a non-technical person trying to navigate this complex world of web app architecture. Then, have a look at a simple web application architecture diagram below.
The web application architecture is different depending on the project's needs and business objectives. There is a simple process defined for you below to understand how architecture binds everything together.

A detailed understanding of web app architecture is indispensable, especially if you want to build your super app. So with the help of ARFASOFTECH's developers, who have experience working on 300+ projects, we are revealing a closer look into the architecture.
This element searches for the IP addresses and domain names to give the relevant server the end user’s request.
It sends incoming requests to one of the multiple servers. Also, delivers answers to the end user & prevents overcharging by task distribution.
It processes user requests & sends JSON/XML docs back to an initial browser. For this, it refers to the database, job queue, & cache server, etc.
It offers a variety of instruments to organize, delete, perform, & update computations. Without any intermediary, the interaction between web app servers & job servers is done.
This one offers easy, quick data storage & search. When the user receives the info from the server, the search results are cached so that future requests are returned much faster.
The services are built in the form of a separate application once the web app achieves a specific level. These are not visible among other web app components. However, services can interact with them as well.
It stores & exchanges data online via the Internet. And the data is sent to the firehouse for processing. Afterward, the additional data is sent to cloud storage & finally, it goes to the data warehouse.
This system sends HTML/CSS/JavaScript files & images. It delivers the content taken from the end server around the world so users can load sources.
There are two optional elements also: Job queue and full-text search.
The architecture, as also stated above, can vary. But the standard structure followed in large-scale web application architecture or enterprise web application architecture is 3-tier architecture.
Nowadays, web apps are created via the separation of their principal functions, in simple words, called tiers. Let’s see why this is desirable!
The 3 tier web application architecture has certain advantages which make it desirable, such as
The architecture is divided into layers for better comprehension and smooth working.
Building layers in web application architecture helps in the identification of each component of an application. It helps in making changes in other layers without affecting the overall applications-enabling easy writing, debugging, management, and re-using of code.
Let’s look deep into layers too.
The presentation layer is the front end app-including static content and a dynamic interface that is visible to the end users. HTML, CSS, or JavaScript are the technologies used, and potential frameworks are Vue, Angular, and React.
It is part of the app’s backend, consisting of core application logic & outlines all internal flow for requests and data. The most convenient for this layer is servers, serverless clouds, or PaaS. PHP, Python, JavaScript & Ruby are programming languages with Django, Spring & Laravel as frameworks.
This layer is closely linked with the business layer as it gets the required information from the servers. Here the data service layer separates the business logic from the client side whilst processing the requests. Therefore, all layers work independently & communicate with each other via relevant components.
After understanding the layers, it is potent that you know about the components involved.
The web application architecture consists of three components.
It is the key component that interacts with the users, receives the input, and manages the presentation logic whilst controlling user interaction.
This server-side component handles business logic & processes user requests by diverting the requests to the right component & manages entire application operations.
This component provides the required data for the application and handles data-related tasks. In the case of multi-tiered architecture, data servers can manage business logic too.
All these components are present in every architecture, but the number may increase or decrease depending on app requirements.
The type of architecture in web applications determines the pattern of component interaction showing the way app logic allows the server and the client-side interaction.
If you are confused about how to select the best web app architecture, then the types below may help you choose one as per your requirement.
This architecture is designed to show relevant content only and to make this happen. It first loads the required web page & then updates the representation of the content with the requested info.
Some of the pros and cons of SPAs are below
The Microservices disperse the functionality to deliver lightweight services separately. In particular, there is a use of APIs for communication if a complex problem arises.
The pros and cons of microservices below can help you decide
PS: Thanks to microservices architecture’s flexibility and stability, famous businesses like Amazon, Netflix, and eBay are adopting it for their complex needs.
In this type, both server & infrastructure management is outsourced to a third-party provider. It is reliable for companies who want to delegate their server & hardware management and concentrate on front-end development tasks instead. It also allows working on small functions in apps.
The pros and cons of serverless architecture are
With the capability of functioning on any browser and on any device, these apps offer rich functionality and easy installation. URLs instead of app stores are used to discover and share these apps.
The pros and cons of progressive web apps are below
These apps are widely used in industries like entertainment, finance, and eCommerce.Want to read more about PWAs, Click Here.
The most widespread type, which is grounded on a user receiving the entire HTML upon request. Also known as server-side or 1.0, this scheme needs the web page to reload to which page logic and general business logic react.
The legacy HTML web app has its pros and cons highlighted below
Last, but not least, it is important that you understand the models present in the industry so that you can align the architecture as per your app needs.
The enterprise web application architecture models are different based on two criteria.
It is the simplest model where there is only one server and one database for all requests and responses. But if the single server goes down, the app shuts down immediately.
Considering the user's needs, the one database model is rusty; however, it's a great way to test your web app idea or MVP.
There is no single web server for data storage; when a client inputs the request, the related server writes it to the sole database managed outside. It is relatively reliable as there are more than two servers, and a backup server is always available. There is only one database that is dangerous in terms of website crashes.
There are several web servers and databases, ensuring efficiency. So you have two options for database storage. Here, you can choose to keep identical databases or distribute information.
In the event of a crash, the entire app is not lost, but you can lose some data (to prevent this, install load balancers).
Choosing or designing the web app architecture is just the first tricky step but yet the most important one. Most people rely on replicating the designs and strategies of popular web apps; this can do more damage than good. Because oftentimes, they don’t match your business needs.
To avoid this, follow these best practices in web application architecture.
