Filed under: Uncategorized — sa @ 7:59 AM

DTU (or Database Transaction Unit) represents the level of resources allocated for a database (Azure SQL DB) and it depends of following elements:

  • IO Reads / Writes
  • Memory
  • CPU

DTU applies to a single DB while eDTU applies to a elastic pool (many) of databases. In this scenario the unit used to measure the resources consumption is eDTU (elastic DTU) and it’s computed as an aggregation of resources of resources of all databases from current elastic pool.
