Amazon EC2 On-Demand Pricing: Instance Families, Regional Multipliers, and the Graviton Crossover (2026)
EC2 On-Demand is not one price — it is a matrix of family, size, OS, tenancy, and region. In us-east-1 (June 2026), a m7g.large Linux instance runs $0.0816/hr while a GPU g5.xlarge is $1.006/hr. Most bill surprises come from wrong family choice, not wrong size.
