Just a quick note article didn't mention: smallest Fargate instance you can get is 512mb, around 15$ per month (+ vpc costs). But, If you have a compose file, then you can fit multiple containers in a single instance.
Not sure if this is based on their earlier pricing, as I know there was a price reduction, but I'm calculating ~$9 per month at 0.25 vCPU + 0.5GB memory.
