VVCR manages your Instance Types depending on the current availability in the Region. This may cause some of your Instance Types to not always appear in the Cluster Creation menu. VVCR will hide Instance Types if there’s not enough room in the Region to spin up a Cluster at that size.
For example, this account has 8 instance types enabled:
- c5.4xlarge
- c5a.4xlarge
- c5a.8xlarge
- c5a.xlarge
- t3.large
- t3.medium
- g4dn.4xlarge
- g4dn.xlarge
All of the Instance Types are available when EU-West-3: Europe (Paris) is selected.
But only 5 of these instance types are available when AP-Northeast-3: Asia Pacific (Osaka) is selected. This is due to the current amount of AWS users in the region.
When this happens, use one of the available instance types, select the next closest region, or check again later.
