> Vendor lock-in seems to be similar - you use some middleware, you're locked in. Is there that much difference between building your infrastructure in DynamoDB vs using IBM DB/2? To me, they seem to create similar levels of "lock in" and create an equal barrier to switching out to a new system... and if you want your data, you're going to dump it, reformat it, and start over. Or am I misunderstanding your point?
