What makes J2EE suitable for distributed multitiered applications?

components that make up a J2EE application are installed on different machines depending on the tier in the multitiered J2EE environment to which the application component belongs


Client-tier components run on the client machine.
Web-tier components run on the J2EE server.
Business-tier components run on the J2EE server.
