Yes, it's one way but it's not flexible, and scale app need to restart the app as well.
As I said I may have some heavy operations which will definitely need more than 2G.

In my opinion the ideal way is that we just set a maximum value for each process, but during the running of the process, we don't pre-allocate the memory as we specify as the maximum in deployment.

I suggest you manually “cf scale -m 2G“ after your app has booted.
Type “cf scale --help” for more info.

Hello, all

When pushing an application to CF, we need to define its disk/memory limitation.
The memory limitation is just the possible maximum value will be needed in this
application, but in most time, we don't need so much memory.
For example, I have one application which needs at most 5G memory at startup some
some specific operation, but in most time it just needs 2G.
So right now I need to specify 5G in deployment manifest, and 5G memory is
allocated.

Take m3.large VM for example, it has 7.5G.
Right now we can only push one application on it, but ideally we should can push more
applications, like 3 since only 2G is needed for each application.

Can the resources of a IDLE application be shared by other applications?
It seems right now all the resources are pre-allocated when pushing application, it
will not be released even I stopped the application.
