Resilience posture
Five coverage ratios over real resources, and an explicit statement of the substantial part of the resilience surface the collector does not observe.
What it is
Five signals, each a coverage ratio over real resources, collected across every enabled region: database multi-zone configuration, database automated backups, auto scaling group zone spread, load balancer zone spread, and object storage versioning.
Why ratios rather than counts
A count says how many resources are configured well. A ratio says what proportion are, which is the governance question.
How GovIntel applies it
Signals with no in-scope resources are recorded and excluded from scoring. The domain is rated only when both governance concerns, survival and recoverability, are evidenced across at least the minimum number of distinct resources counted per family.
What it does not observe
Point-in-time recovery on managed NoSQL, backup plans, block storage snapshots, network file systems, distributed relational databases, container and serverless compute, cross-region replication, and standalone compute instances.
For a predominantly serverless estate its coverage of the real resilience surface is close to zero.
