Database deployment failed

Can you please tell me, why database server is not getting deployed. I used all basic options.

Also i am trying a project about database migrations. But i got error thats Data Migration Service (DMS) is not alllowed. Is there any alternative or lab ?

I tried this in the playground for this service, and it works for me. I think you’re just “higher end” in your parameters than we allow. Here’s mine, which were not:

This sounds like a premium Azure service, and of necessity, the playground is fairly limited in what it will allow. I’d guess that we just don’t enable this in the playground.
