`FARGATE` will maintain tasks just for having the `base` value between the bunch.<br/>
It will get at least 2 of them since the `base` value is `2`.
`some-custom-ec2-capacity-provider` will run tasks just for being the provider with the `base` value defined.<br/>
Aside assigning it the 2 base tasks as per configuration, the scheduler will just ignore
`some-custom-ec2-capacity-provider` due to its weight being `0`.
`some-custom-ec2-capacity-provider` will just be ignored during scheduling due to its weight being `0`.<br/>
