Some organizations may not want to migrate all of their applications to server-based computing at once. For example, an organization may use certain heavy-duty applications such as CAD/CAM, multimedia and programming compilers. These applications require lots of CPU and memory resources and put a substantial strain on the server. It may not be ideal to immediately migrate these programs to a server-based computing (SBC) architecture. It allows companies to migrate some programs to SBC and keep others on users local desktops.
