  8. 8. ( ) GUSTAVO HOMEM Partner and CTO @ Solid Angle AWS 6 year cost was calculated using 3 year upfront payment for a m5.4xlarge machine + extra general purpose storage. Colocation 6 year cost was calculated by duplicating hardware (for redundancy) and colocating on 2 different datacenters – twice the hardware is available.
