	// 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.
