Web application architecture: Definition, components, models, and types

The Internet is no longer about static web pages and longer loading times. Over time, the Internet has made a shift towards active user engagement as well as extended functionality by means of visually pleasing and powerful web applications. As a result, the terms of components of a web application has come to life. This is because most developers are looking to benefit from web apps and attract as many users as possible via opportune offerings. So if you want to venture onto a web application development project, it is important to choose the components of a web application as well as the model of web app components. Making the right picks are important for the success of a web app. So now, we – ArrowHiTech would like to introduce to you guys the complete guide of Web application architecture, includes the definition, components, models, and types. Let’s go!

What is the definition of Web application architecture?

Basically, web application architecture is a framework (or some people might call it a mechanism) that states its main external and internal components, the relationship and interaction between those application components (middleware system, user interfaces, and databases). This way, web experience will be enabled and can be used by clients.

Nevertheless, if you want to build a scalable product that has high efficiency and is reliable, robust and secure, this architecture is not something you should ignore. All stakeholders including developers, clients, or even end-users should join in the planning of web application to customize it as per expectations.

As a result, when we say the components of a web application, we can mean any of the following: 

#1. UI/UX components

As the name implies, this includes activity logs, dashboards, notifications, settings, statistics, etc. Of course, these components have nothing to do with the operation of a web application architecture. Instead, they are part of the interface layout plan of this kind of architecture. This helps improve and streamline your architecture.

#2. Client Component

The client component is developed in CSS, HTML, and JS. As it exists within the user’s web browser, there is no need for operating system or device-related adjustments. The client component is a representation of a web application architecture’s functionality that the end-user interacts with.

#3. Server Component

This kind of the components of a web application can be build using one or a combination of several programming languages and frameworks, including Java, .Net, NodeJS, PHP, Python, and Ruby on Rails. The server component has at least two parts; app logic and database. The former is the main control center of the web application while the latter is where all the persistent data is stored.

What are the models of web application architecture?

In addition of components of a web application, we will deliver you a lot of useful information of web application architecture’s models.

Models of the architecture
Models of the architecture

#1. The “one server, one database” model

This is the simplest as well as the least reliable web app component model. Such a model uses a single server as well as a single database. A web app builds on such a model will go down as soon as the server goes down. Hence, it isn’t much reliable. As a result, this is not typically used for real web applications. It is mostly used for running test projects only.

#2. The “multiple servers, one database” model

The idea with this type of architecture component model is that the webserver doesn’t store any data. When the webserver gets information from a client, it processes the same and then writes it to the database, which is managed outside of the server. This is sometimes also referred to as a stateless architecture.

#3. The “multiple servers, multiple databases” model

Doubtless to say, this is the most efficient web application component model because neither the webservers nor the databases have a single point of failure. There are two options for this type of model. Either to store identical data in all the employed databases or distribute it evenly among them. Note: when the scale is large, it is advised to install load balancers.

#1. Single-page applications

They work like a desktop application that can interact with the web browser by rewriting the current web page with new data from the web server. This way clients can enjoy a better user experience as the web application won’t create any interruption. At the moment, this is the most popular web application architecture.

#2. Microservices architecture

This is the practice of dividing a web application into small autonomous units and developing each of them separately. To be specific, this framework has a number of advantages that allows developers to not only enhance productivity but also speed up the entire deployment process. As such, they don’t necessitate to be built using the same programming language.

#3. Serverless architecture

In this type of web application architecture, an application developer consults a third-party cloud infrastructure services provider for outsourcing server as well as infrastructure management. So When choosing this type of architecture, the need to manage infrastructure is no longer there. All you need to focus on is developing the functionalities.

Final words of Web application architecture

Above all, this article includes everything you may need to know in the most basic way of web application architecture, especially the components of a web application. After all, it’s prominent that this type of architecture, like the Internet, is continuously evolving. Moreover, everything of a web application is greatly determined by the model and type of the chosen architecture. Hence, before getting started with the development, take time to explore.
