Provision only the bare amount needed to meet your workload

• scale in/out as needed
• use a mix of reserved/spot/on demand
  • reserved covers the minimum usage
  • spot/on demand scaled as needed
• less wastage with many smaller instances as opposed to fewer large instances
• t2 types cost-effective for bursty workloads, as with a web-server

Tag all resources

• e.g. environment (dev, testing, prod), function (web-app, rendering etc)
