You roll your own infrastructure not to pad your resume, but because the capex spend provides you with a lower opex, and presumably you have capital to spend. Cloud charges a premium for elasticity. Not everyone needs elasticity. Capacity planning is a skill, you can get better at it over time, and other technologies (VMs, containers, whatever) can help bin pack for better operating cost than you'll ever see in the cloud.
