Web applications have two sides to them: a frontend and a backend. The frontend is what we see when a webpage loads on our web browsers, while the backend is the other side of the application and mostly where the developers interact.
What is a website?
Characteristics of a website
For server-side rendering, web applications rely on specialized web servers such as Apache, Apache Tomcat and NodeJS. The backend, in addition to a web server, also contains an application server that hosts the business logic of a web application and the database to store and retrieve information.
Why do you need business logic in a website?
Facilitating the flow of information between a user interface and a database is only a subset of what business logic does. Business logic is actually part of the web application’s program and its primary job is to imitate real-world business rules. For example, business rules dictate rules for data creation, storage, changes, interaction with business objects, and the formation of routes.
Business rules describe the operations and define constraints that apply to an organization. The operations collectively form a process; every business uses these processes to form systems that get things done. Let’s take an example of a web application running monetary transactions:
- The person making the request must have the authority to do so.
- The transaction must be atomic.
- The transaction may have reporting requirements to the government if it’s over a certain amount.
How a web application works
- User triggers a request to the web server over the Internet, either through a web browser or the application’s user interface.
- The web server forwards this request to the appropriate web application server.
- The web application server performs the requested task – such as querying the database or processing the data – then generates the results of the requested data.
- The web application server sends results to the web server with the requested information or processed data.
- The web server responds to the client with the requested information that then appears on the user’s display.
Why do you need a web application?
When you navigate from one webpage to another, the client sends a new request to the web server which in return sends a new set of code for the web browser to load. From a developer’s point of view, the server sends a different HTML page per route. Frequent browser-to-server roundtrips slows down the process of content consumption and hinders the user experience.
Users accustomed to mobile apps on their Android and iPhone prefer a single page approach to the applications they interact with. Single page applications, or SPAs, are the basis of modern web development. The emphasis is on loading the home page, entire static content and rendering the dynamic content on the fly as the user interacts with the web application.
Our clients often prefer web applications due to their loading speed. But there are more benefits to this type of application. Continue reading to find out more.
Characteristics of a web application
When you open Facebook on Chrome it displays your timeline. However, when you try to load comments to one of your photos, the server feeds the data on the fly. Thanks to SPA functionality, you can see in real time if somebody is writing another comment on the photo. SPAs are the reason you don’t need to download Skype or Teams on your device and can access it from a compatible browser.
The idea of putting native desktop and mobile apps on your web browser makes life a lot easier, but it comes with a potential bottleneck: performance. Web applications are sandboxed inside a web browser and thus have limited performance apparatus than a native application.
An older iPad that runs the Google Docs mobile app just fine may struggle to pull up the Google Doc web app on Safari due to these constraints. For an organization, a web application brings immense benefits in terms of time and cost. Their developers won’t have to maintain various versions of the same applications and can get by with a reliable web application that works across all major browsers.
Benefits of web applications
The future of web applications
If web applications can deliver a similar performance to mobile apps, they’ll eventually replace them. From a business perspective, web apps make more sense as they’re easier to maintain due to the fact they don't have to maintain separate instances of the application for each platform. One application that doesn’t need downloading, installing, updating, and loads on most web browser in seconds sounds like a dream come true for developers, organizations, and users.
Developers now just have to maintain one application that works on any device with one of the compatible browsers installed. Organizations can build applications with fewer resources; their developers will bill them for less hours. Users would love the idea that they can interact with a higher quality application without ever downloading and installing it.
Example of web applications
A number of world organizations are moving their legacy application stack to the web. Web applications offer unparalleled accessibility, on-demand collaboration, instant communication, and seamless collaboration.
Software vendors can unlock the potential of SaaS by moving their existing software offerings from license-based distribution per device to a subscription model per account. SaaS is more rewarding than licensing deals.
The reason Microsoft, the leader of enterprise productivity tools, felt threatened by Google Workspace was due to Google’s advances in web application development at the time. Microsoft had a tough time catching up with Google’s competition until they came up with their own in the form of Office 365. Office 365 turned out to be a thumping success but not until Google pushed Microsoft to build a web version of their favorite Office applications. Web applications are more than trends, they’re a smarter way to do things.
How to get your own web app
If you don’t have a programming background, you’ll probably struggle to build a functional and useful web application. Luckily for you outsourcing is a great way to get what you want and boost your business.
