Just a quick word of warning… if you’ve got a Mongo DB serverless database running you better keep an eye on the bill. I’ve just been stung for $155 for 2 1/2 days. To say I’m shocked is an understatement .
The pricing structure is really not user friendly and TBH I feel a bit scammed. Mongo Team - I feel like there should be some kind of warning during the setup about the possibility of this, or maybe force the user to set a price cap per month. Perhaps example pricing would also help…
FYI - I only uploaded about 4.5 million docs (1.5 gb) and did some ‘manual testing’ which involved searching for records and displaying the data on a webpage. I also had a server add new docs every 15 minutes (about 20-100 docs)… not exactly enterprise scale stuff.
I work in the serverless PM team and I am sorry your experience has been less than perfect. As serverless is one of the latest offering from MongDB, we are always looking to improve the product. I will be reaching out to you to discuss your issues in more details.
So I setup a serverless Mongo DB database to test a small project I’m working on… it’s ended up costing me $190 for 3 days. Luckily I spotted the bill - God only knows what it could have been by the end of the month!
So what did I do wrong?
Simple - I chose ‘serverless instance’ instead of a fixed monthly contract. The serverless sounds cheap - just pay for what you use… however the pricing structure isn’t very user friendly and you can be caught out BIG TIME! How big? Well my database of 4.5million simple documents, with me as the only user, cost me ~$190 for 3 days!
Please don’t be like me.
Mongo team, you really need to work on the docs for that product. Give some examples of how the pricing works in ‘real life scenarios’. Searching online shows I’m not the first to be hit by this… I hope I’m the last!
On the plus side the M5 server I’ve now got is very good… and not any slower! It will also take at least 6 months to run up the same bill… not 3 days!!
Big warning! Mongodb serverless is a real scam. I was charged $312 for a 7 days for nothing. More than $40 per day!! We just uploaded a database of small online community application. 1.5 gbyte. Less than 200 active users a day. Their pricing claims that cost of read is $0.1 per million reads. This means my 200 users made 400million reads a day!!
I tried to reach them through a support chat but every response from them takes hours. I requested some details. NO ANSWER.
Bottom line I was a big fun of mongodb and deployed a dozen of projects. I recommend my customers mongodb whenever it may fit requirements. It is very convenient database especially for startups,but they caught us this time
They always were more expensive then others, but this time they bet my imagination. I’m really disappointed and angry. I hope my lesson will be helpful for others. So I’m still waiting for a details. Will share with you in my blog.
We have a very simlar problem. For a day when nobody used our platform, mongo says they received 0.1M read, which is impossible. With a database of 95MB and 200 users using our platfor for 2 hours, they say we did more than 200M read. I think they are wrong computing the reads (or this is a scam)
