How we got our AWS bill to around 2% of revenue
If you end up in the lightsail world and you are not utilising Amazon's other services then its probably cheaper to do this with another provider. Someone like Contabo or Hetzner will get you VMs at substantially less cost with similar fixed hardware and just give you the box but for a lot less a month. At these low scales with a completely open source stack Amazon isn't good value in my opinion. It is as you grow and it provides the scale that it becomes valuable.
