What is the optimal hardware requirements for tableau server?

  • I'm pursuing Tableau Certification and for testing purposes Tableau says 4 cores, 8 GB RAM and 15 GB disk space. But recommended one says 8 physical cores, 32 GB RAM and 50 GB disk space.

    Now I am stuck as 2nd configuration seems to be an overkill. I don't have heavy requirements. How should I decide on cores and RAM?

    I shall be connecting Tableau to MySQL for real time dashboards
