In addition, you can change the Pricing Tier to use **Serverless** *Compute Tier* instead of **Provisioned** to achieve a more "auto-scaled" approach to a workload. For example, for this workload if you chose a min vCore value of 2 and max VCore value of 8, this workload would immediately scale to 8vCores.
