Questions

## MongoDB: frequently asked

Atlas or self-hosted MongoDB?

Atlas removes operational work and runs on AWS, Google Cloud and Azure. Self-hosting gives control but needs care with replication, backups and upgrades.

Does MongoDB support transactions?

Yes, it supports multi-document transactions. Still, models that need many cross-document transactions may suit a relational database better.
