Fat Servers OR Fat Clients

December 26, 2007 at 2:29 pm (Unit 1) ()

  • Client/Server applications can also be differentiated by how the distributed application is split between the client and the server.
  • The fat server model places more function on the server.
  • The fat client does the reverse.
  • Groupware, transaction and the web servers are examples of fat servers; database and file servers are examples of fat clients.
  • Distributed objects can be either.

Fat Server Vs Fat Client

Fat Client

  • Fat clients are the more traditional form of client/server.
  • The bulk of the application runs on the client side of the equation.
  • In both the file server and database server models, the clients know how the data is organized and stored on the server side.
  • Fat clients are used for decision support and personal software.
  • They provide flexibility and opportunities for creating front-end tools that let end-users create their own applications.

Fat Server:

  • Fat Server applications are easier to manage and deploy on the network because most of the code runs on the servers.
  • Fat servers try to minimize network interchanges by creating more abstract levels of service.
  • Transaction and object servers, for example, encapsulate the database.
  • The client in the fat server model provides the GUI and interacts with the server through remote procedure calls (or method invocations)
  • These are used for mission-critical applications, represent the new growth area fro PC-based client/server computing.
