I’ve tried to learn about it these past few days from available resources online.
As Chris highlighted it’s somewhere linked to the delivery/deployment/integration.
It seems to be mostly about automation of things like:
- dashboards - quality metrics
- production metrics and user insights
- monitoring, alerting and recovery systems
- unit, integration, ui, api checks
- analytics to make data-driven decisions
- test data scrub/protection from real data
- security, performance scanners/analyzers
Generally whatever one automates that would help to understand the product state (quality) at various points during the CD/CI.
