/**
 * <p>Enables EBS encryption by default for your account in the current Region.</p>
 *          <p>After you enable encryption by default, the EBS volumes that you create are
 *     	always encrypted, either using the default KMS key or the KMS key that you specified
 *       when you created each volume. For more information, see <a href="https://docs.aws.amazon.com/ebs/latest/userguide/ebs-encryption.html">Amazon EBS encryption</a> in the
 *       <i>Amazon EBS User Guide</i>.</p>
 *          <p>You can specify the default KMS key for encryption by default using <a>ModifyEbsDefaultKmsKeyId</a>
 *       or <a>ResetEbsDefaultKmsKeyId</a>.</p>
 *          <p>Enabling encryption by default has no effect on the encryption status of your
 *       existing volumes.</p>
 *          <p>After you enable encryption by default, you can no longer launch instances
 *       using instance types that do not support encryption. For more information, see <a href="https://docs.aws.amazon.com/ebs/latest/userguide/ebs-encryption-requirements.html#ebs-encryption_supported_instances">Supported
 *         instance types</a>.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, EnableEbsEncryptionByDefaultCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, EnableEbsEncryptionByDefaultCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);
 * const input = { // EnableEbsEncryptionByDefaultRequest
 *   DryRun: true || false,
 * };
 * const command = new EnableEbsEncryptionByDefaultCommand(input);
 * const response = await client.send(command);
 * // { // EnableEbsEncryptionByDefaultResult
 * //   EbsEncryptionByDefault: true || false,
 * // };
 *
 * ```
 *
 * @param EnableEbsEncryptionByDefaultCommandInput - {@link EnableEbsEncryptionByDefaultCommandInput}
 * @returns {@link EnableEbsEncryptionByDefaultCommandOutput}
 * @see {@link EnableEbsEncryptionByDefaultCommandInput} for command's `input` shape.
 * @see {@link EnableEbsEncryptionByDefaultCommandOutput} for command's `response` shape.
 * @see {@link EC2ClientResolvedConfig | config} for EC2Client's `config` shape.
