How deeply does Effective Platform Engineering cover uptime?

Distinguishes availability from self-correcting resilience and recommends nonproduction testing, without detailing HA configurations.

Uptime

As explained in Effective Platform Engineering

High availability is the design of a system to maintain service access despite component failures or maintenance.

High availability (HA) keeps services accessible through redundancy and the redirection of traffic to healthy infrastructure. It concerns uptime; resilience is distinct, describing a system’s ability to self-correct after failure. section 1.3.3 section 8.3

Apply HA with production confidence and developer access in mind:

Test HA and resilience configurations outside production; skipping HA there can undermine confidence in releases. section 8.3
Balance nonproduction costs against the time developers lose when blocked and the delays to revenue-generating features. section 8.3

Platform services pipeline

Epetech’s demo configurations omit full HA options for services such as metrics-server, kube-state-metrics, and event-exporter. That simplification is for demonstration; production environments should enable HA. section 8.3
