neither the v1 services contrib or docker are production ready, but both should be options for you if you don't care too much about that data and just want productive development.
i believe the v1 services contrib should work with CF v2 because CF v2 is still compatible with the v1 Service Broker API. dr nic i believe has experience with this.
for using the docker service broker on aws, you can see this release from ferdy [1]. when users request a new mongodb in the cf marketplace, they'll get a docker container just for them. it is a single node docker host, so the capacity of the number of containers will be limited by the VM size you choose.
