Designing a scalable system can be a tricky thing, before you jump into action check out a great post by Ricky Ho where he describes the eight common design patterns:

1. Load Balancer
2. Scatter and Gather
3. Result Cache
4. Share Space
5. Pipe and Filter
6. Map Reduce
7. Bulk Synchronous parallel 
8. Execution Orchestrator

I think Rick done a wonderful job. Thanks ! Can you think of anything else?
