Testing BigBlueButton with 2 cores x 4Gb RAM of DigitalOcean VPS

I began to work with BBB 10 days ago. For the first tests i follow recommended requirements for the server: 4 cores & 8Gb of RAM. But i decided to test with less requirements (2 cores & 4Gbs!!) and it works!!! I'm fascinated with both: this great software and this great VPS/droplets of DigitalOcean.
