Types of Web Applications Architecture

Web-Applications-Architecture

Web applications have become a crucial factor of business in today’s world. By using the web applications, businesses can now expand and become simpler and achieve its objectives much faster. These applications can help target numerous clients and customers at a time. Organizations are rapidly taking up this aspect of the internet by creating web applications with the help of developers to bring together their business demands. Web applications are important for a number of reasons.

It is no longer possible for the businesses to make out a growth in their market share unless they have a suitable web application. While bigger businesses may be able to afford their own development teams for such purposes, smaller companies outsource the work to web development companies to get the same advantage at a reduced cost. It helps organizations attain new customers and let them know about the organization and the services provided by it.

Server-side HTML Web Application

This is the most widespread web application architecture. The server generates HTML content and sends it to the client as a full-fledged HTML-page. Sometimes this architecture is called “Web 1.0” since it was the first to appear and currently dominates the sphere of web development.

A huge amount of data is transferred between the server and the client. The user has to wait until the entire page reloads, responding to minor actions, for example, when only a part of the page needs to be reloaded. UI templates on the client depend directly on the frameworks applied on the server. Due to the limitations of mobile internet and the vast amount of transferred data, this architecture is hardly applicable in the mobile sector. There are no means of sending instant data updates or changes in real time. If we consider the possibility of real-time updates through the generation of ready chunks of content within a page, we’ll go ahead of this architecture.

JS generation widgets (AJAX)

This is an evolved architecture of the first type. The difference is that the page, which is displayed in the browser, consists of widgets (functionally independent units). Data is uploaded to these widgets via AJAX query from the server: either as a full-fledged amount of HTML, or as JSON, and transforms (through JavaScript templating/binding) into the content of the page. The option of uploading chunks of HTML excludes the necessity of using Javascript-MV* frameworks on the client side; in this case, something simpler can be used (for example, jQuery). By lowering interactivity we boost up the development speed and make functionality cheaper and more reliable.

The foremost advantage is that updates from the server turn up only for the part of the page requested by the client. It’s also good that widgets are separated functionally. A particular widget is in charge of a part of the page; partial changes will not affect the whole page.

Service oriented single-page web apps (Web 2.0, HTML5 apps)

The term “Web 2.0” isn’t quite acceptable here. One of the peculiarities of web 2.0 is the principle of involving users into the filling and repeated adjustments of content. Basically, the term “Web 2.0” means projects and services which are actively developed and improved by users themselves: blogs, wikis, social networks. This means Web 2.0 isn’t bound to one technology or a set of technologies.

Let’s figure out the essence of this architecture. An HTML-page is downloaded from the server. This page is a container for JavaScript code, which addresses a particular web service and retrieves business data only. The data is used by JavaScript application, which generates the HTML content of the page. This architecture is a self-sufficient and somewhat complex JavaScript application, where part of the functionality is shifted to the client side. To compare, the architecture of the second type cannot show a high number of interrelated and structured functions.

All the transactions and activities that turn out online across the world are results of web applications. Web applications are more like well-planned strategies for various businesses. With online transactions through secure networks, intelligent assistance in selection of products/services, etc., it is simply inching one step closer to achieving your business goals.

Not only do these applications drive business growth at a faster rate, they are pretty indispensable for almost all businesses because of the value addition.
