If you add up the cpu/memory requirements for redis, rabbitmq, mysql etc., that itself adds up to a beefy machine. Then the network traffic from the users. Better to package/run these as docker components on 2 beefy VM's w/ a LB from a provider like DigitalOcean, Vultr, Linode or Hetzner. You can pick up AWS etc, but be mindful of all the costs that add up. Kubernetes is a no-no unless you have some level of proficiency in kubernetes, or are willing to invest the time.
