I haven't seen anything yet explaining e.g. how you would have 9 mongo instances and just 2 web app instances with a load balancer.
Is this supported? If so where are the docs?
I have a feeling that this is not what you are asking, but in case it is...
vmc push myapp --instances 2 --mem 64M --path ../mybits --url some-sub-domain.cloudfoundry.com --no-start -nvmc create-service mongodb --bind myappvmc create-service mongodb --bind myapp...vmc create-service mongodb --bind myapp
If what you are trying to ask is to we support a mode of operation where this is a scale out mongodb service that lets you ask for 9 units of parallelism across a single document store, the answer is no, not yet. This is really a statement on the status of the mongo service, or sql service that's in the current code drop. Its totally feasible to implement a sql service that's configured for N read replicas, or a master-master system, etc. We have not done this in the current, open source services though.
OK. Obviously this is pretty fundamental, to be able to configure your services to be replicas/shards etc and all that kind of stuff.
Postgres master/slave etc
