 * <p>Creates a placement group in which to launch instances. The strategy of the placement
 *             group determines how the instances are organized within the group. </p>
 *          <p>A <code>cluster</code> placement group is a logical grouping of instances within a
 *             single Availability Zone that benefit from low network latency, high network throughput.
 *             A <code>spread</code> placement group places instances on distinct hardware. A
 *                 <code>partition</code> placement group places groups of instances in different
 *             partitions, where instances in one partition do not share the same hardware with
 *             instances in another partition.</p>

 * ```javascript
 * import { EC2Client, CreatePlacementGroupCommand } from "@aws-sdk/client-ec2"; // ES Modules import
 * // const { EC2Client, CreatePlacementGroupCommand } = require("@aws-sdk/client-ec2"); // CommonJS import
 * const client = new EC2Client(config);
 * const command = new CreatePlacementGroupCommand(input);
 * const response = await client.send(command);
 * ```
 *
 * @see {@link CreatePlacementGroupCommandInput} for command's `input` shape.
 * @see {@link CreatePlacementGroupCommandOutput} for command's `response` shape.
 * @see {@link EC2ClientResolvedConfig | config} for EC2Client's `config` shape.
