ECS Fargate host units calaculation

[gurugogi]

Hi Team,

We have AWS ECS Fargate monitoring enabled, some Fargates will run as service and some will run as Task definition.

Same like VMs Fargates also consume 1 host unit for 16GB memory in Fullstack mode.

I want to understand  host units consumption by these Fargates specifically for Fargates running as service and Task definition. 

If Fargate(with 16GB memory) is running as Service it will consume 1host unit from quota as it will be running always but if Fargate is running as Task defination it wont run always, it runs based on some schedule or events so here host unit is consumed only during that run and that particular host unit is released back to Host units quota once Fargate has finished running ?
Please clarify whether I understood it correct or not.

Thanks

Hi @gurugogi 

It all depends on what licence you have.
With the standard Host Unit model, there will always be a licence consumed (unless the host is disabled then it will go back into the pool)

The Host Unit Hours licence works best in these situations.

Hi Radek,

Thanks for reply.

For earlier discovered fargates OneAgent is offline so here it will consume host units ?

[radek_jasinski]

If it is offline, it should not consume the licence.

Thanks for confirmation Radek.
