Importance of Isolating Front-end and Back-end in Web Applications
Introduction to a web application architecture
Web application architecture is defined as a medium provided to interact with all other applications and databases in order to make sure that they work in collaborative manner. The functioning of web application involves dividing the architecture into two major parts i.e. frontend and backend.
On the other hand, Backend is such a portion of website that a user cannot see. It is also known as server side code and is highly responsible to manage data and interactions in an organised manner. The communities of black end make use of front end in order to send and receive information that is used to display in the form of web page.
The below image creatively depicts the roles of frontend and backend of a web application.
The conventional way of doing things
The conventional website development system tightly couples all the elements related to web design. The digital content that is shown to the user is stored in the backend along with the database. The frontend displays the published data directly on HTML pages without any extra processing.
Technologies under the hood
There are numerous backend technologies that allow tight coupling of the backend and frontend. Few of these are described below.
JSP/Servlet: The JavaServer Pages were developed by Sun Microsystems to allow the developers to create dynamic HTML pages with the help of Java language. The JSP code was included in the HTML code. The browser then used to convert it into Java servlets in order to improve the scalability and performance.
PHP/HTML: The PHP language was used in the traditional model to connect web pages with external application with the help of Common Gateway Interface. The PHP was included in the HTML markup and this information was then sent to web servers using URI requests. PHP language also allowed the developers to create dynamic HTML pages with the help of various template engines.
.NET/aspx: The .NET programming language is used to perform various computations on the server side. It serves pre-processed ASPX pages. These pages contain certain server side code which is computed before sending the HTML to the client side.
Drawbacks of closely coupled frontend and backend
The closely coupled frontend and backend development model was quickly replaced by other methods due to its various disadvantages. The main disadvantages of this development model were
- The traditional method was only successful in the development of simple websites. The web pages developed using this technique were unable to effectively deliver multiple types of content like videos, photos, audio and
- The server was responsible for performing all the processing before delivering the content to the users. These processing requirements reduced the number of users that can be handled by the server.
- The customization process was less agile because any changes in the backend had a significant impact on the front end of the website.
- The use of traditional method increased the time required to develop and maintain a website.
Front-End Technologies – Independent UI development
Front-end technologies are those technologies that are used to develop the interfaces for web applications. The structure of report, and its design and behaviour are implemented through the front end technologies. The front end is also known as client side programming as the code being developed can be served without any web application server. There are different types of front end technologies which perform the task differently to develop the interface of web application. All front end technologies have its own components that are used to develop the user interface such as BEM provides the structured CSS organisation into single module and Bootstrap uses the powerful plugins that are built on jQuery. This helps in building an impressive web application.
There are multiple frontend technology frameworks that can be used as per the target audience and the amount of data to be handled. At Abk Multiservices, we work with a bunch of such frameworks and technologies to provide a blazing fast web application with a responsive layout. Some of the technologies we work with are: Angular 2+, ReactJS as well as MeteorJS.
Strong isolated Backend
The strong isolated back-ends are very important for the web applications as the security priorities are focused on the back-end and user management. The front-end receives the details from the user and send it to the back end for storage and processing. The strong isolated backend receives the information and secure it from the other world. The users of the web applications expect the quick response from the application after providing the input. The storage and processing of data to develop a result and providing response is the work of strong isolated back-ends.
At Abk Multiservices, we understand backend technologies very well. We help you in choosing the right backend technologies for your projects. We are never restricted by a technology. So far, we have our hands put into NodeJS, Java, PHP as well as Python. Our team is always ready to take a step ahead and learn new technologies as needed to match the market demand.
Advantages of Loosely Coupled Configuration
The loosely coupled configuration provides many benefits in the web application. The main advantage of this loosely coupled is that the components can be easily replaced with other components that perform same services. Through this, the front end working of web application does not get affected and the changes in the back end can be performed easily. Another advantage is that the system can be written in different programming languages and then it can be run on different operating systems. Along with this, the system can be built by different team members and integrated at one point. This helps in developing the web application in quick manner as all the parts of web application are built side by side. Thus, the loosely coupled configuration is very effective for the development of the web applications.
The frontend and backend applications are two main components of web application architecture. The frontend technologies help in building the user interface of the web application through which the user can perform different functions over web application. The backend technologies give response to the input of users in web application. The backend technologies take input from users, store and process it to get the results and gives response accordingly. There are two types of bonding between frontend and backend technologies such as loosely coupled configuration and tightly coupled configuration. The loosely coupled configuration provides more advantages in web applications as it allows the modification of backend technology without affecting the front end of the system.
