What is a DTU?
DTU is a bit difficult, as it can be described as an object, but it is not actually a real object. DTUs are performance units to which a certain percentage of the total performance of the database server is allocated in CPU, memory, and read or write rates. The offered performance levels contain between 5 DTU (in the Basic service level) and 4,000 DTUs (in the Premium service level P15).
The larger the number of DTUs, the greater the performance of the database. Another criterion for the selection of a performance level is the maximum size of the database.
Also, the maximum size, that can reach the database depends on the selected performance level. The maximum size of the database per level is:
- Basic: 2 GB
- Standard (S0 – S12): 250 GB
- Premium (P1 – P6): 500 GB
- Premium (P11 + P15): 4 TB
- Premium RS: 500 GB
Is that all now? No, also the number of simultaneously concurrent requests (maximum concurrent workers), the number of concurrent logins (maximum concurrent logins), and the number...
