Thanks a lot for this Ref card. For a long time I wanted to clear my concepts on scalability and stuff - this surely helped to get the knowledge real quick.

Hi,
How can we ensure the transaction scalability at design time. For example, Customer is expecting system to support 100000 transactions per minute. If the developed and deployed system proved to be unable to handle 100000 trx/minute then there is high penalty clause. I don't have a luxury to create actual prototype or POC. In this case how should I ensure transaction scalability and satisfy customer?
Thanks and Regards,
Rahul
