About the baker and so on

#1

Hi, guys. We are thinking about start baking and have a questions that would help us to understand how to optimize our work. We had some thoughts about creating an autoscale groups or similar:

  1. Can we scale baker horizontally somehow?
  2. Will baker consume all the resources of the VM where it is launched?
  3. Which metric best of all will show us that baker should be scaled?
  4. Should we scale other services (accuser, endorser, node itself) with the baker?
  5. Can we create an load balancer that will manage an incoming traffic? Does it requies any additional settings or it is as simple as TCP load balancing?

  1. Why do you need to scale the baker? It is a single-threaded process and if you double-bake then you loose all rewards for the entire cycle.
  2. No. We run a 2vCPU VM for our baker/endorser/node/accuser with 2GB RAM. The baker hardly uses any CPU. This is proof-of-stake, not proof-of-work. Horsepower is not needed; that’s the whole point behind PoS. This is why you can bake on a raspberryPi.
  3. You don’t need to scale the baker.
  4. No. You could have backups VMs on standby but you should absolutely never run more than 1 baker at a time per private key otherwise you risk double baking.
  5. You don’t need this.
