Web Application Architecture

Is web application structure a new term for you? 

While the concept of web application structure is related to web app development. In the past years, the way web app development is taking over native app solutions, both users and developers have become curious about web app solutions.

Basically web applications are those that can be easily accessed on a browser or on any kind of internet-enabled device. Another reason behind its popularity is its low cost, ensuring high reach to the audience, offering a native-like app experience, and enabling you to implement innovative approaches to deliver an excellent user experience.

There is a vertical shift has been witnessed in web app development as it can easily scale up as your business grows.

But what makes it scale up so efficiently? It’s only a Web Application Structure!

So before you step ahead to build a web application for your business, you need to have an in-depth understanding of web application structure, its components, types, and the importance of Web application diagrams.  

So let’s start with the basics of the topic…

What is Web Application Structure?

Web application architecture refers to the design layout of the web application components (including an application’s servers, databases, middleware systems, and user interfaces) and how they interact with each other. 

It is far more concerned with the concept that how the data is delivered through the HTTP and how it will be perceived by the client-server and backend server.

Moreover, the web app structure also secures that valid data is present in all user requests and creates and manages all records while offering permission-based access and authentication. 

So in a simple language, web app structure is all about the layout and logical connection between the backend server and client-server. 

But before you kickstart your web development project, you must know, why it is important to pay attention to the web application structure diagram…

The Importance of Web Application Architecture

Why does web application architecture matter and how it will impact you?

With each passing year, marketing trends are kept changing and user expectation is keep evolving. In that scenario, working with the same web app structure developed with old, tired technologies can cause a great hurdle in your business growth.

So here comes the importance of developing a strong web structure that helps you stay stronger in the market. However, working with that same old version will drag your business into a big ball of mud.

The biggest benefit of a well-planned web app architecture is it can easily scale up as per the changing and growing needs of the business. Web apps with the right architecture can easily adapt to the latest market trends to deliver a fast user experience. 

To further improve the app’s performance, you can also handle several development tasks at the same time by carefully diving the structure into several small modules. This will minimize the development time and make it easier for you to integrate new functionalities without causing any effect on the overall system. 

Now let’s talk about the security of web apps. Well, web architecture divides the application into various blocks that are individually secured and minimize the risk of security threats. To create a future-proof architecture, you can choose to hire a web application development agency in the UK

How Does Web Architecture Work?

The mechanism of the web application architecture is depending upon various projects. As different businesses have different requirements so many of their components are determined by the project requirements and business needs rather than just technology. However, changing or adjusting the web app’s component won’t have any impact on the app’s overall success. 

Let’s check out the video to understand everything about web application architecture and how it work…

So majorly keep in mind that all web applications are made up of two important components including:

  • Client-Side: Basically known as the front of the web app, where the codes are written in CSS, HTLM, and JavaScript.
  • Server-Side: It is also known as the backend of the app where the entire business logic has been controlled and responds to HTTP requests. The popular programming languages used to develop backend codes are Java, PHP, Ruby, Python, and more.

Let’s take an example to understand how doe Web app development structure works.

After typing a URL, like ‘Amazon.com’, the browser will send a request to the Domain Name Server which will recognize the IP address and forward your request to the Amazon server. Once the server receives the request, it will send it to the data storage in order to locate the requested page, which is displayed to the user on the browser.

Understanding the 4 Layers of Web App Structure

If you are surprised to know why Web applications are surging in demand and how do they satisfying user experience, then you should that modern web apps are following the layered architecture. Usually, web apps have 4 layer architecture including presentation, business, persistence, and database layers.

In some cases, small-size applications have three layers, whereas other types of apps may have five or six-layer architecture depending upon the complexity of the project.

Call us today for custom website development services.

Let’s take a look at the details of the layers of architecture:

  • Presentation Layer: It is basically the front end of the app- what users see and interact with. The presentation layer includes the specific UI design needed to display to the users. 
  • Business Layer: This layer of architecture defines the goal and logic of the app. It processes browser requests and executes the business goal associated with the requests and then finally sends it presentation layer.
  • Persistence Layer: It is also known as the Data Access Layer which is closely connected with the business layer. It has a database server that helps in retrieving data from corresponding servers. 
  • Database Layer: This layer is responsible to handle all the data and ensure data security by simply separating the business logic from the client side.

Keep in mind that each layer works independently but every layer is closely connected with one another. 

What Type of Web Application Architecture Defines Your Purpose?

While hiring a web application development company in the UK is a simple way to get started. But without knowing what type of web app you want to build, it is tough to define the web app structure. To select the most appropriate architecture, you need to consider various factors such as app logic, features, functionalities, and business requirements. The right architecture will clearly define the purpose of your app as a whole.

So here are the 4 major types of web applications that you can consider developing:

1. Single Page Application Architecture

SPAs are a single-page typical website that loads each new page separately. And the biggest example of SPAs is Facebook and Gmail.

2. Server Side Rendering (SSR)

Due to a high page-load delay, Server-Side Rendering (SSR) was abandoned and an architecture for routing the user to only the data he or she needed, giving him or her a smooth, fast browsing experience, popularized by React.

3. Microservice Architecture

A microservice is a smaller, specialized piece of software. The use of the Microservice Architecture can lead to more productivity and quicker software releases.

Because they are not directly interdependent, such programs do not require all components to be written in the same programming language. Developers now have the freedom to choose the technology of their choice.

4. Serverless Architecture

A serverless architecture uses managed infrastructure, such as AWS or Google App Engine, to support building scalable web apps without having to provision or maintain servers.

What Are The Best Web Application Architecture Best Practices and Tools?

An architectural design is just the first step, but your web application’s success depends on the architectural patterns you choose. The fact remains that replicating the strategies of popular web applications can do more harm than good since oftentimes they don’t correspond to your business needs. A few best practices can be followed to avoid such situations. 

Here are some practical tips and tools that help you create a successful web application structure for your app:

Make sure you choose an appropriate web application architecture…

Your architecture’s components and elements might be dramatically disordered, which is difficult to manage without having a thorough structure in place.

Set Your Technical Restrictions To Achieve Quality Product…

The best and most useful features aren’t always possible to include in your web application architecture. But by paying close attention to their qualities and setting achievable technical goals, you will get the most out of every part you include.

Never Try to Duplicate The Concept…

Doing the same things the more successful companies are already having will never help you succeed if you are trying to replicate their concept. Just think like that What’s good for one company doesn’t have to be as good for your company. Understand 

your business goals and accordingly build a strategy for web app architecture. 

Apart from that, here are some of the best choices of tools that can access to improve the web app experience:

Tools For Web Application Architecture

  • IDE Tools

There are various IDEs including WebStrom, NetBeans, Giuthub’s Atom, and AWS Cloud9 that help you increase productivity.

  • Integration of Tools

To deliver a seamless and unified experience, it is worth integrating tools such as MuliSoft, JitterBit, Cleo, and Automate.io.

  • Frameworks and Libraries

There are multiple-choice frameworks and libraries including Angular, React, Python, Express, Vue, React Native, Node.js, and more that enable you to produce high-quality products.

What is a Web Application Architecture Diagram?

A web application architecture diagram is a visual representation of the components and connections that make up a web application. This type of diagram typically includes elements such as user interface components, business logic, databases, servers, and other external services.

The diagram allows developers to understand how data flows between different components in a system and make informed decisions about their web applications. By studying a web application architecture diagram, developers can make sure that the architecture of their application is optimized for scalability, security, and performance.

What is a 3-Tier Architecture?

A 3-tier architecture is an architectural style that divides an application into three distinct layers: a presentation layer, a business logic layer, and a data access layer. The presentation layer is responsible for the user interface, the business logic layer is responsible for the business rules and processes, and the data access layer is responsible for retrieving and manipulating data from the underlying data store.

This separation of responsibility makes it easier to design and develop complex applications that can be scaled, maintained, and reused in different contexts. It also provides flexibility to easily add or remove features without disrupting other components of the application.

The three-tier architecture has become increasingly popular over the years due to its ability to ensure scalability, reliability, maintainability, and security for enterprise-level applications. It is often seen as the best option for property management apps because it offers an efficient way to manage large amounts of data.
