• Scenario 1: We need a database for our testing environments, The size of data is 250 GB
  • DTU (General purpose)

• Scenario 2: We need a database for ticket reservation system with alteast 100 GB store
  • VCOre (Business Critical/Azure Hybrid Benifit/Reservations)

  • I would recommend serverless or Business Critical
