The success of the web is large because a large part of theoretical constructions devoted to hypertext was rejected in favor of simple, pragmatic solutions, which served as the basis of an ideal design.
The problem with corporate web services is that they involve a rigid partnership. This is often justified, but the most exciting applications can be built on a fragile foundation.
Definition of Web Applications
A web application is an application in which the client is a web browser, and the server is a web server. The Internet browser can be an implementation of so-called thin clients.
It displays web pages, is usually part of the operating system, and is updated and maintained by the vendor.
The application’s logic is focused on the server. The Internet browser is most often responsible only for displaying information downloaded from the server and transferring user data to the server.
One of the advantages of this approach is that clients are independent of the user’s specific operating system, and web applications are thus cross-platform services. Also known are custom web application development services.
Features of Web Applications
The web application receives a request from the client and performs calculations, after which it forms a web page and sends it to the client over the network using the HTTP protocol.
A web application can be a client of other services, such as a database or another web application located on another server.
A new approach to web application development called Ajax has recently gained popularity.
The web application pages are not entirely reloaded but only loaded from the CHANGE server, making them more interactive and productive.
Independence from the Client’s Operating System
The application is created once for an arbitrarily chosen platform and deployed on it. However, different implementations of HTML, CSS, DOM, and other specifications in browsers can cause problems in the development of web applications and further support.
Ease of Use
A site visitor should understand how to use the site within 10-15 seconds. Don’t expect anyone to read the manual or spend 1-2 hours learning the menu and command system.
RSS is perhaps the only widely used web service because it is simple.
And complex corporate sets are still waiting for their hour. Support simplified programming models, and you will get loosely bound partners.
Think syndication, not coordination. Simple web services – like RSS or REST-based services – deal with data syndication without trying to control what happens to the information at the other end of the chain.
The idea of end-to-end data transmission is one of the basic ideas of the Internet itself.
Excellent Response Time to User Actions
From the moment of clicking on the link to the appearance of the result often passes more than 1 second (and sometimes more).
Therefore, a person has time to notice the delay and even get bored. The programmer’s task is to reduce the reaction time of the application as much as possible.
At a minimum, the BEGINNING of the response should appear in less than 10 seconds.
A Large Number of Users
In successful web projects, tens of users visit the site per second. Therefore, it is worth thinking about optimizing the speed of program execution. For mobile development, go now.
Resistance to Attacks
Due to open access to web application management, the number of hacker attacks on such applications is very high.
Giant Arrays of Data
Databases with billions of records have only recently ceased to be exotic, and therefore there are still no tools for efficiently searching and manipulating such large amounts of information.
Network, Distributed, Parallel Computing, Agent Systems
Modern Internet applications often communicate with each other. For example, an “e-shop” site uses a bank site to accept payment for a product. Entertainment sites show advertising blocks from other sites, etc.
Software is a Service, Not a Product
One of the main characteristics of modern Internet applications is that they are distributed as a service, not a product.
This, in turn, leads to fundamental changes in the business models of software development companies. The global SaaS market generated $152 billion in revenue last year.
We are already used to the fact that applications for business automation are, by default, ready-made systems in which the necessary functions are refined. This approach is justified in most cases, but not always. Suppose existing solutions are highly complicated by functionality, and we only need a few business functions. In that case, it is easier to write an Internet application from scratch as a Web application WebApps, or Web application.
