Disadvantages/cons of Grid Computing

1) Grid software and standards are still evolving.

2) Learning curve to get started.

3) Non-interactive job submission.

4) A fast network connection between the computer and network is necessary.

5) The computer that are used may not to be fast enough or might be slow down.

6) Require specific software to make it work.

7) Computer can drop off connection to the computer on the grid can get disconnected anytime so its hard to control all of them.

8) Not all hardware run at the same speed – local processors may not have some capabilities to process tasks.

9) Limited control over the hardware since dispersedly located across the network.

10) Resource allocation can be hard – logically having more nodes and controlling the resources is difficult task.
