How deeply does Think Like a CTO cover cloud elasticity?

Provides operational warning signs but does not detail automatic scaling mechanisms.

Cloud elasticity

The ability of a system to automatically adjust provisioned resources in response to changing demand.

Cloud elasticity is the ability to adjust provisioned resources as demand changes. Its business value is paying for capacity when it is needed rather than maintaining the same capacity through busy and quiet periods. section 8.3.1

Check whether cloud operations show signs of static infrastructure:

A nearly identical bill each month, especially in a seasonal business, may mean capacity is not changing with demand. section 8.3.1
Inability to scale up or down as load changes is a direct warning sign. section 8.3.1
Release downtime and manually managed disk space suggest servers are being treated as fixed assets. section 8.3.1

Elasticity depends on how applications are operated, not simply where servers run. Cloud use still requires skills, and it is not a cure for every problem. section 8.3.1
