Every rule whose selector covers this component's kind or its category. Whether a rule fires depends on the design: its properties, its edges and its groups.

Stateful node without zone redundancyerror

stateful-node-without-zone-redundancy

A stateful compute node pinned to exactly one availability zone disappears with that zone, and its state goes with it. Nodes inside a cell are exempt, because there the cell is deliberately single-zone and redundancy comes from the other cells.

— all of these hold:
— the node's `stateless` is false
— the node sits inside exactly 1 availability-zone group
— this does not hold:
— the node sits inside at least one cell group

2# Auto Scaling (ESS): a scaling group that automatically adjusts the number of compute instances based on
3# policies you define ("What is Auto Scaling?"). That page states a scaling group is a logical grouping of
4# identical instances with minimum and maximum counts and associated load balancers, lists scheduled,
5# event-triggered, custom, health-based and fixed-number modes, and notes Auto Scaling itself is free while
6# you pay for the ECS and ECI instances it creates. Those instances are ones you patch, so managed is false.
