The Difference Between Web-Based and Client-Server Applications

Today you can access software applications in many different ways.

With the rising costs of software application implementation and ongoing support, you face the difficult decision of whether to select traditional client-server applications or to go with the newer Web-based applications.

Architectural Differences

According to Information-Management.com, client-server applications are typically two-tiered, consisting of an in-house server loaded with the operating system, a database and application software and a client personal computer loaded with a software application that interacts with the server. Web-based applications are usually three-tiered, consisting of a database server, a Web server and possibly a separate application server. You use an Internet browser to connect to and use the application.

Financial Concerns

Companies pay for Web-based applications on a subscription or usage basis. Client-server applications, however, are purchased up front, usually with a huge initial cost and ongoing licensing and maintenance fees, which can wind up costing as much as 20 percent per year of the original fee according to The IQ Group.

Support Considerations

Servers need regular maintenance such as upgrades, patches and hardware maintenance. All costs to purchase, maintain and upgrade the network for client-server applications are the company's responsibility. A company using a Web-based application through an Application Service Provider, however, is little involved with support.
