How Large Can Nerdio's SQL Database Get?
Only the very largest customers, those that have thousands of session hosts in host pools, have exceeded the 5 GB mark. Please note that this is dependent on the workload and activity. A small customer with a lot of activity and tasks could consume more DB space than a large customer with fairly simple needs.
Note: An S1:20 DTU DB includes 250 GB of storage for the DB in the cost, so there is never a need to worry about increasing the cost. Backup costs depend on the frequency and retention. Even assuming a large DB of 5 GB, weekly backups would be a fairly negligible Azure cost.
