Google Docs, Trello, Netflix, Gmail, Twitter, Slack, G Suite, Microsoft Office 365 and it goes on – the list of web applications marking their presence around the globe is limitless. Web application development services have been getting popular since the 1990s wherein the first web apps were quite simplistic. With time and technology moving faster, the late 90s introduced complex and functionally challenging web apps. And then there was no looking back. Web apps are now an integral and important part of our daily lives and have also proven their mettle on the enterprise front.
There was a time when websites ruled but websites were always informational and that is where the need was felt for an application on the web that can offer interactivity. Here was the advent of web applications that needed access to the Internet, had front-end, back-end but possessed interactivity. For e.g., if you visit a hotel’s web presence wherein you can have a look at their menu, rooms, operational hours, directions etc., it is a website but if you can book a room, pay online etc., it is a web application. As simple as this!
There had to be some strong reason why the web apps were a big hit then and now. Native apps had their share of popularity base but owing to certain reasons, users felt the need for a web revolution.
It would be interesting to have a glimpse at the journey of web apps starting from the 1980s till today:
And the web application arena never looked back!
Imagine the extent to which web application development services has reached. There are categories within categories to understand the depth and coverage of web apps. This section attempts to give a brief overview of the broad spectrum of web apps. Based on the technology being used and the mechanism of building a web app, these app types focus on the technologies and frameworks involved.
Even though the web had been introduced much before, there was a need felt for simply architected web applications that offer a light weighted solution. An OS independent platform was required which could interact seamlessly with the client and the server.
Based on fundamental blocks – HTML, URL, and HTTP, initial web pages were constructed to develop static formatted content and images available on the net. In the architectural flow, the client requested a web page via HTTP request and the web server provided the information as static HTML back. The client’s web browser read through the HTML tags and rendered the page.
The static web apps showed a lack of fundamental functionalities like session management, authorization, personalization, and dynamic content. There was a lack of good quality UI and the experience was limited to browser-based clients. The app content was also restricted to a single source. With an idea of interacting online, static web apps evolved into dynamic web apps in the 1990s.
The basic principle in this architecture is a server focussed one, wherein the web app server takes care of getting information, offering business logic and creating UI. The client would take care of rendering the UI and execute JS operations like validation, session management, and event processing.
The preliminary dynamic web apps couldn’t offer an enriched UI experience. There were certain computational, cross-browser compatibility and scalability issues that came up. These apps were limited to browser-based clients. With new web browsers entering the market, there was a need felt for a more responsive UI that would build dynamic pages, respond to user actions instantly without reloading from the server.
With technology moving faster than ever, the new millennium saw trends moving from static to dynamic, server focussed to client independent, self-building to framework based. There were certain inconsistent features that were hindering the success of RIA. Also, complexity increased owing to UI generation both on the client as well as the server.
The best part of this is that the presentation layer and business logic is totally executed on the client end. Thanks to the introduction of API services, the client gets the information from the server using JS/AJAX. The server reciprocates the data through the different medium like JSON/XML. From there onwards, the data flows to models to views through templates.
MPA work in the traditional manner. Each display or data transmission renders a new page from the server in the browser. These apps are larger than SPAs and have multiple UI levels. Because of latest technologies like AJAX, heavy data transfer between the server and the client is no big deal. Yes, it does add a high complexity factor but is perfect in terms of catering to multiple requirements.
Today, mobile computing is becoming increasingly ubiquitous. Since the world was going mobile frenzy, there was no technology that could afford to be away from mobile devices. There was a need for web applications that would function on any mobile device just the same way it would in other devices. Of course, with ever-changing mobile devices, it was challenging but surely a must.
With the utilization of HTML and AJAX, mobile web app development also makes use of RIA technologies like Flash, Silverlight etc. Mobile web apps have almost equivalent usability to RIAs except that they are designed for small sized devices. These apps exist in your mobile device browser, are SEO friendly and doesn’t have to be installed on the device.
Native apps offered good user experience but were limited to certain devices and were inflexible. Mobile websites were efficient and quick but had limited user experience. What was needed was a combination of both – the mobile and the web. And then came Progressive web apps. It associates the best fundamentals of mobile sites and native apps while diminishing their shortcomings.
These categories of web apps operate based on the required workflow. It could be based on any of the technologies that support web apps.

Relying on the latest semantic web techniques, these web apps are utilized to offer knowledge for humans as well as machines. Certain situations where these apps can be useful are web mining, knowledge reusability etc.
Being document-centric, these web apps are static HTML docs which reside on the web server. They are sent to the client depending upon demand. There is a manual intervention in terms of updating these apps. These apps are simplistic, steady and static.
As the name suggests, these apps comprise interaction through different media like radio buttons, forms, menu options and more. Fast by nature, these web apps, and related links respond based on user requests.
A step further to Interactive, these apps possess the feature of modification by the end-user. They have a close coordination with the database for stable and effective data extraction. Structured queries help garner desired information with ease.
