Whether instances should have a public IP addresses associated with them.

Default: - Use subnet settings

getBlockDevices

@Stability(Stable)
@Nullable
default List<BlockDevice> getBlockDevices()

Specifies how block devices are exposed to the instance. You can specify virtual devices and EBS volumes.

Each instance that is launched has an associated root device volume, either an Amazon EBS volume or an instance store volume. You can use block device mappings to specify additional EBS volumes or instance store volumes to attach to an instance when it is launched.

Default: - Uses the block device mapping of the AMI

getCpuCredits

@Stability(Stable)
@Nullable
default CpuCredits getCpuCredits()
