- [EC2 Cost Estimate](https://calculator.aws/#/estimate?%20id=0180036d04e86d221898455f124054dc18922ca5&id=883b6de14b680f78f87f3fffd07b1b99455abd73)
|
|
- utilises servers more
|
|
- DANDIS m6a.2xlarge running at ~10% cpu usually
|
|
- autoscaling
|
|
- fargate possible but annoying
|
|
- EKS
|
|
- dev + prod all we need
|
|
- flat $0.10/hr per cluster
|
|
- 2 Clusters x 0.10 USD per hour x 730 hours per month = 146.00 USD
|
|
- less than a single c5a.xlarge
|
|
3 of which in DANDIS account doing nothing
|
|
- In prod instances max 27% cpu across the last week
