PlacementGroupProps()
public PlacementGroupProps()
Properties
Partitions
The number of partitions.
public Nullable<double> Partitions { get; set; }

Default: 0
PlacementGroupName
the name of this placement group.
public string PlacementGroupName { get; set; }

Attribute: true
SpreadLevel
Places instances on distinct hardware.
public Nullable<PlacementGroupSpreadLevel> SpreadLevel { get; set; }
Property Value
System.Nullable<PlacementGroupSpreadLevel>
Remarks
Spread placement groups are recommended for applications that have a small number of critical instances that should be kept separate from each other. Launching instances in a spread level placement group reduces the risk of simultaneous failures that might occur when instances share the same equipment. Spread level placement groups provide access to distinct hardware, and are therefore suitable for mixing instance types or launching instances over time. If you start or launch an instance in a spread placement group and there is insufficient unique hardware to fulfill the request, the request fails. Amazon EC2 makes more distinct hardware available over time, so you can try your request again later. Placement groups can spread instances across racks or hosts. You can use host level spread placement groups only with AWS Outposts.
Default: - no spread level
Strategy
Which strategy to use when launching instances.
public Nullable<PlacementGroupStrategy> Strategy { get; set; }
Property Value
System.Nullable<PlacementGroupStrategy>
Remarks
Default: - PlacementGroupStrategy.PARTITION

otherwise
