Are you sure you went with RAID1 with 4x disks instead of RAID10?
Good spot - this is wrong. It should've been 4 x 3.84 TB NVMe SSD RAID 5. My colleague set this bit up so I'm not entirely up to speed on the terminology.
We cut our Mongo DB costs by 90% by moving to Hetzner

#22Always consider if 12 hours of lost revenue is worth the savings. Recently hetzner has been flakey with minimum or no response for support or even status updates that anything was wrong. My favorite was them blaming an issue on my side just to have a maintenance status update the day after about congestion.
Atlas wasn't giving us any support for $3K per month. Hetzner at least have some channel to contact them, which is an improvement. That said, if their uptime is rubbish them we'll probably migrate again. Moving back to Atlas is not an option as we were getting hammered by the data transfer costs and this was only going to increase due to our architecture. Thanks for reading!
500GB isn't a lot of data, and $3K/month seems like an extortion for that little data.
Having said that, MongoDB pricing page promises 99.995% uptime, which is outstanding, and would probably be hard to beat that doing it oneself, even after adding redundancy. But maybe you don't need that much uptime for your particular use case.

#23Note, if you're looking for MongoDB Enterprise features you can find many of them with Percona Server for MongoDB, which you can use for free the same way as MongoDB Community

OVH is allegedly pretty good. I host all my personal stuff on Hetzner right now so I can't speak to it personally.
We also use OVH and have so far not had any downtime in about 6 months.

#25MongoDB Atlas is so overpriced that you can probably save already 90% by moving to AWS.
Most of the cost in their bill wasn't from MongoDB, it was cost passed on from AWS
I don't remember the numbers (90% is probably a bit exaggerated) but our savings of going from Atlas to MongoDB Community on EC2 several years ago were big.
In addition to direct costs, Atlas had also expensive limitations. For example we often spin up clone databases from a snapshot which have lower performance and no durability requirements, so a smaller non-replicated server suffices, but Atlas required those to be sized like the replicated high performance production cluster.

Nice, thanks for the tip!

#27I’m starting to worry about this Hetzner trend. It can end up to get the price skyrocketing.

#28You probably want to store the backup somewhere else, ie. not Hetzner. They are known to just cancel accounts and cut access.
Good shout. I think we'll also run replicas on other providers. We've got some complex geo-fencing stuff to do with regards to data hence why we're just on Hetzner right now.

Hopefully not. Their console is pretty bad so I reckon that will put a lot of people off.
