NoHaInstanceCount
The number of EC2 instances in your non-High Availability Rack cluster. This parameter is only used when HighAvailability is set to false. For HA Racks, see InstanceCount.
| Default value | 1 |
| Minimum value | 1 |
Use Cases
- Running a single-instance development or staging Rack to minimize costs
- Increasing to 2 or more instances in non-HA Racks that still need some level of workload distribution
- Scaling up a non-HA Rack to handle higher application loads without switching to full HA mode
Additional Information
When HighAvailability is true, the InstanceCount parameter is used instead and NoHaInstanceCount is ignored.
Non-HA Racks run with a minimum of 1 instance. While you can increase this value, keep in mind that non-HA mode does not provide the same redundancy guarantees as HA mode. For production workloads that require fault tolerance, consider enabling HighAvailability instead.
