 ** HostId **   <a name="outposts-Type-ComputeAttributes-HostId"></a>
 The host ID of the Dedicated Host on the asset.   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 50.  
Pattern: `^[A-Za-z0-9-]*$`   
Required: No

 ** InstanceFamilies **   <a name="outposts-Type-ComputeAttributes-InstanceFamilies"></a>
A list of the names of instance families that are currently associated with a given asset.  
Type: Array of strings  
Length Constraints: Minimum length of 1. Maximum length of 200.  
Pattern: `^(?:.{1,200}/)?(?:[a-z0-9-_A-Z])+$`   
Required: No

 ** InstanceTypeCapacities **   <a name="outposts-Type-ComputeAttributes-InstanceTypeCapacities"></a>
The instance type capacities configured for this asset. This can be changed through a capacity task.  
Type: Array of [AssetInstanceTypeCapacity](API_AssetInstanceTypeCapacity.md) objects  
Required: No

 ** MaxVcpus **   <a name="outposts-Type-ComputeAttributes-MaxVcpus"></a>
The maximum number of vCPUs possible for the specified asset.  
Type: Integer  
Required: No

 ** State **   <a name="outposts-Type-ComputeAttributes-State"></a>
The state.  
+ ACTIVE - The asset is available and can provide capacity for new compute resources.
+ ISOLATED - The asset is undergoing maintenance and can't provide capacity for new compute resources. Existing compute resources on the asset are not affected.
+ RETIRING - The underlying hardware for the asset is degraded. Capacity for new compute resources is reduced. AWS sends notifications for resources that must be stopped before the asset can be replaced.
+ INSTALLING - The asset is being installed and can't yet provide capacity for new compute resources.
Type: String  
Valid Values: `ACTIVE | ISOLATED | RETIRING | INSTALLING`   
Required: No
