An example:
I have a Java web application running on App Engine in which I plan to do the below things.
1. Create a compute instance (Linux).
2. Connect to it and install some packaged software readily available (Example: Install LAMP stack).
all using Google Client APIs for all the different cloud services.
What I'm looking for right now is ...instead of me installing each software one by one....is there any API for the market place....where I can take an existing available deployment there and install it instead. Let me know if this doesn't help.
