Memory depends on your data and the engine you are using. Spark puts all data into memory across the Spark cluster so if that is one machine, 4g will not allow more than toy or example data. Remember that PIO and Machine Learning in general works best with big data.
BTW my laptop has 16g and I can only process limited data in an all-in-one configuration. Unless you are connecting to external services like Spark, or HDFS, etc, 4g will not get you very far.

If you are not looking to customize PIO itself, you may download pre-built binaries (which is available starting 0.12.0-incubating) from https://www.apache.org/dyn/closer.cgi/incubator/predictionio/0.12.0-incubating/apache-predictionio-0.12.0-incubating-bin.tar.gz <https://www.apache.org/dyn/closer.cgi/incubator/predictionio/0.12.0-incubating/apache-predictionio-0.12.0-incubating-bin.tar.gz>. That way you don't have to spin up a big machine to build it if you're just trying it out. We are in the process of updating our web site to include installation using binaries. Apologies for the delay.

How much memory does the build environment has? A virtual server with 1GB in DigitalOcean . A system with 2GB of RAM would be enough?
