Our notes
Choosing MongoDB Atlas Atlas Flex
Who it suits
A small production app, a prototype that has outgrown the free tier or a project with uneven traffic. Flex charges by usage with a hard monthly ceiling, so a quiet month costs little and a busy one cannot surprise you beyond $30.
Compared with other MongoDB Atlas plans
Flex sits between M0 Free (512 MB of storage, not for production) and the M10 dedicated cluster ($0.08 an hour, 2 GB of memory per node, 10 GB of storage). It offers ten times the storage of M0, 5 GB. Like M0 it runs on shared CPU and memory, so performance depends on other tenants.
Before you sign up
The base usage band works out to about $8 a month; heavier use moves you into higher bands up to the $30 cap. Once you regularly hit the cap, the M10 at $56.94 a month by MongoDB’s figure gives you a dedicated cluster for less than twice the price. Data transfer and backups may be charged separately, so check the Atlas pricing page.
