 * <p>Purchases the Scheduled Instances with the specified schedule.</p>
 *          <p>Scheduled Instances enable you to purchase Amazon EC2 compute capacity by the hour for a one-year term.
 *          Before you can purchase a Scheduled Instance, you must call <a>DescribeScheduledInstanceAvailability</a>
 *          to check for available schedules and obtain a purchase token. After you purchase a Scheduled Instance,
 *          you must call <a>RunScheduledInstances</a> during each scheduled time period.</p>
 *          <p>After you purchase a Scheduled Instance, you can't cancel, modify, or resell your purchase.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
 * ```javascript
 * import { EC2Client, PurchaseScheduledInstancesCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, PurchaseScheduledInstancesCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);
 * const command = new PurchaseScheduledInstancesCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link PurchaseScheduledInstancesCommandInput} for command's `input` shape.
 * @see {@link PurchaseScheduledInstancesCommandOutput} for command's `response` shape.
 * @see {@link EC2ClientResolvedConfig | config} for EC2Client's `config` shape.
