class Aws::AutoScaling::Types::Ebs
Describes information used to set up an Amazon EBS volume specified in a block device mapping.
@note When making an API call, you may pass Ebs
data as a hash: { snapshot_id: "XmlStringMaxLen255", volume_size: 1, volume_type: "BlockDeviceEbsVolumeType", delete_on_termination: false, iops: 1, encrypted: false, throughput: 1, }
@!attribute [rw] snapshot_id
The snapshot ID of the volume to use. You must specify either a `VolumeSize` or a `SnapshotId`. @return [String]
@!attribute [rw] volume_size
The volume size, in GiBs. The following are the supported volumes sizes for each volume type: * `gp2` and `gp3`\: 1-16,384 * `io1`\: 4-16,384 * `st1` and `sc1`\: 125-16,384 * `standard`\: 1-1,024 You must specify either a `SnapshotId` or a `VolumeSize`. If you specify both `SnapshotId` and `VolumeSize`, the volume size must be equal or greater than the size of the snapshot. @return [Integer]
@!attribute [rw] volume_type
The volume type. For more information, see [Amazon EBS Volume Types][1] in the *Amazon EC2 User Guide for Linux Instances*. Valid Values: `standard` \| `io1` \| `gp2` \| `st1` \| `sc1` \| `gp3` [1]: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSVolumeTypes.html @return [String]
@!attribute [rw] delete_on_termination
Indicates whether the volume is deleted on instance termination. For Amazon EC2 Auto Scaling, the default value is `true`. @return [Boolean]
@!attribute [rw] iops
The number of input/output (I/O) operations per second (IOPS) to provision for the volume. For `gp3` and `io1` volumes, this represents the number of IOPS that are provisioned for the volume. For `gp2` volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting. The following are the supported values for each volume type: * `gp3`\: 3,000-16,000 IOPS * `io1`\: 100-64,000 IOPS For `io1` volumes, we guarantee 64,000 IOPS only for [Instances built on the Nitro System][1]. Other instance families guarantee performance up to 32,000 IOPS. `Iops` is supported when the volume type is `gp3` or `io1` and required only when the volume type is `io1`. (Not used with `standard`, `gp2`, `st1`, or `sc1` volumes.) [1]: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html#ec2-nitro-instances @return [Integer]
@!attribute [rw] encrypted
Specifies whether the volume should be encrypted. Encrypted EBS volumes can only be attached to instances that support Amazon EBS encryption. For more information, see [Supported Instance Types][1]. If your AMI uses encrypted volumes, you can also only launch it on supported instance types. <note markdown="1"> If you are creating a volume from a snapshot, you cannot specify an encryption value. Volumes that are created from encrypted snapshots are automatically encrypted, and volumes that are created from unencrypted snapshots are automatically unencrypted. By default, encrypted snapshots use the Amazon Web Services managed CMK that is used for EBS encryption, but you can specify a custom CMK when you create the snapshot. The ability to encrypt a snapshot during copying also allows you to apply a new CMK to an already-encrypted snapshot. Volumes restored from the resulting copy are only accessible using the new CMK. Enabling [encryption by default][2] results in all EBS volumes being encrypted with the Amazon Web Services managed CMK or a customer managed CMK, whether or not the snapshot was encrypted. </note> For more information, see [Using Encryption with EBS-Backed AMIs][3] in the *Amazon EC2 User Guide for Linux Instances* and [Required CMK key policy for use with encrypted volumes][4] in the *Amazon EC2 Auto Scaling User Guide*.

@!attribute [rw] throughput
The throughput (MiBps) to provision for a `gp3` volume. @return [Integer]
