I'm building a credit card applicatoin that utilizes the BDB JE embedded, and i'm curious about best-practises in relation to implementing stated application towards the cloud. Generally the applying under consideration is really a after sales application using the responsibility to persist, retrieve increase data.

My primary question though is: once the strain on the applying increase, how can you really scale the applying out, as developing a new node around the Amazon . com AWS would effectively produce a new copy from the database, and concurrent use of the BDB JE database is not a choice.

Any ideas or hints regarding how you can achieve scalability here could be greatly appreciated!
