How do I set my aws fargate runs correctly?

[nithish-enk]

Hi Everyone,

I am facing an issue with setting aws fargate runs (I am running tests using playwright/artillery)

Below are the full details

1. I want to achieve arrivalRate of 10 vu for 10 mins

{
          duration: 600, // 10 minutes
          arrivalRate: 10,
          name: 'Baseline-10TPS',
},

As per recommendation in https://www.artillery.io/docs/playwright#resource-recommendations

Calculation:
1 vCPU per VU
1 gb per 1 vcpu

600 secs * 10 per sec = 6000 vCPUs
6000 GB

16 vcpus per task => 375 tasks (with 16 vcpus, 16 GB of memory)

So I tried using below
--launch-config '{"cpu": 16384, "memory": 32768}' --count 375

Problem:
When I use 375, 375 AWS fargate tasks are created. (There is confusion on what count corresponds to. In doc it says count corresponds to load generator containers, but these are AWS fargate tasks right?)
But since I have used 375 as count, total vu users are multiplied by 375. (i.e instead of 6000 I am seeing 6000*375 total vusers)

I see from https://www.artillery.io/docs/reference/cli/run-fargatecount that count will multiply load by a factor.

But without using count how do I scale resources?
