- Cloud Run sends up to 80 concurrent requests to one instance by default, with 1000 as the maximum finding
- DynamoDB on-demand tables still throttle when traffic more than doubles the previous peak finding
- One DynamoDB partition serves 3000 read and 1000 write units per second whatever the table capacity finding
