Need some guidance on reducing the cost of my Aurora serverless database.
If you're sensitive to costs and don't have the need for complex relationships, you can save a ton by going with DynamoDB on demand billing. It'll almost definitely be cheaper. At your current load, it might be less than a dollar a month. More on reddit.com

How Aurora Serverless v2 works - Amazon Aurora
Amazon Aurora Serverless v2 is suitable for the most demanding, highly variable workloads. For example, your database usage might be heavy for a short period of time, followed by long periods of light activity or no activity at all. Some examples are retail, gaming, or sports websites with periodic promotional events, and databases that produce reports when needed.

There's no way to sugar coat this. The cost of Aurora Serverless v2 seems very high. In fact, v2 ACUs are twice the price of the original v1 ACUs ($0.12 per ACU Hour versus $0.06 per ACU Hour).

October 31, 2022 -

Hey there,

Sorry if I lack any technical jargon for this question, I'm still pretty novice to AWS.Right now I have a desktop application that has a leaderboard function. For this I decided with would be best to go down the RDS path. I know pretty little about connecting and running databases, so I opted to go with the serverless route, and wanted to access the database using the Aurora API/ lambda.

I saw AWS deprecated mySQL for serverless 1.0, and since serverless 2.0 does not support the aurora API, I went with the postgres option, as I could still use the API.

I think this is the first mistake, as it seems the minimum ACUs for the postgres option is double of the mySQL. But either way my database has a min and max of 2 ACUs which is probably far more than my application needs. I would estimate max, my user pool will be about 50k and its just storing simple leaderboard numbers.

After one month of running the database, my monthly bill came out to ~230 dollars, which is just a lot especially since I have not even launched this product yet.My main cost was in just running the database :

$0.08 per Aurora Capacity Unit hour running Amazon Aurora PostgreSQL Serverless

2,840.991 ACU-Hr

$227.28

So does anyone have any advice on where to start in reducing the cost ? Should I move off postgres?Would running the EC2 and manually managing the database be cheaper? Would no longer using the API be cheaper ? Any help appreciated

Edit : Wow I just realized while posting this my ACU numbers did not add up and it turns out I was running a second database all month with nothing in it. So thats half the cost atleast lol. But still my questions apply
