# Resource Blocks

Resource blocks are units of compute capacity in Tableau Cloud. Resource Blocks run Tableau Prep Conductor flows. Each Resource Block can run one flow at a time so the number of flows you can run concurrently is equal to the number of Resource Blocks that you have.

By default, you get one Resource Block per site. One Resource Block is equivalent to one [concurrent flow job](https://help.tableau.com/v0.0/online/en-gb/cloud_manager_capacity.htm#flows). You can purchase additional resource blocks for additional concurrent flow jobs capacity by contacting your Tableau account manager or learn more by visiting the Tableau [pricing](https://www.tableau.com/en-gb/pricing/teams-orgs).
