What are the characteristics of modern website applications or web apps or software?
The following attributes are encountered in the vast majority of WebApps.
Network intensiveness. A WebApp resides on a network and must serve the needs of a diverse community of clients. The network may enable worldwide access and communication (i.e., the Internet) or more limited access and communication (e.g., a corporate Intranet).
Concurrency. A large number of users may access the WebApp at one
time. In many cases, the patterns of usage among end users will vary greatly.
Unpredictable load. The number of users of the WebApp may vary by
orders of magnitude from day to day. One hundred users may show up on
Monday; 10,000 may use the system on Thursday.
Performance. If a web app user must wait too long (for access, for server-side processing, for client-side formatting and display), he or she may decide to go elsewhere.
Availability. Although expectation of 100 percent availability is unreasonable, users of popular WebApps often demand access on a 24/7/365 basis. Users in Australia or Asia might demand access during times when traditional domestic software applications in North America might be taken off-line for maintenance.
Data-driven. The primary function of many WebApps is to use hypermedia to present text, graphics, audio, and video content to the end user. In addition, WebApps are commonly used to access information that exists on databases that are not an integral part of the Web-based environment (e.g., e-commerce or financial applications).
Content sensitive. The quality and aesthetic nature of content remain an important determinant of the quality of a WebApp.
Continuous evolution. Unlike conventional application software that evolves over a series of planned, chronologically spaced releases, Web applications evolve continuously. It is not unusual for some WebApps (specifically, their content) to be updated on a minute-by-minute schedule or for content to be independently computed for each request.
Immediacy. Although immediacy—the compelling need to get the software to market quickly—is a characteristic of many application domains, WebApps often exhibit a time-to-market that can be a matter of a few days or weeks.
Security. Because web apps are available via network access, it is difficult, if not impossible, to limit the population of end users who may access the application. In order to protect sensitive content and provide secure modes
