Why does Azure Cosmos DB take so long to deploy? When I tried deploying Azure Cosmos DB (SQL API) via ARM template, it took ~20 min for deployment to complete. Why is that?

Deployment for a new Cosmos account requires involves multiple underlying resources and there are a number of steps involved that must be done in series to provision and connect these resources before the account is ready to accept requests.
Things that can impact provision time include, number child resources (databases, containers), number of regions and amount of throughput. In addition there can be other factors as well including the number of control plane operations overall in a region.
All that said, we are working on optimizations designed to reduce the amount of time it takes to provision new Cosmos DB accounts.
Hope that helps.
I just provisioned a new Cosmos DB today and it took a little less than 10 minutes. East US region.
