/**
 * Client for accessing AWSBudgets asynchronously. Each asynchronous method will return a Java Future object
 * representing the asynchronous operation; overloads which accept an {@code AsyncHandler} can be used to receive
 * notification when an asynchronous operation completes.
 * <p>
 * <p>
 * Use the Amazon Web Services Budgets API to plan your service usage, service costs, and instance reservations. This
 * API reference provides descriptions, syntax, and usage examples for each of the actions and data types for the Amazon
 * Web Services Budgets feature.
 * </p>
 * <p>
 * Budgets provide you with a way to see the following information:
 * </p>
 * <ul>
 * <li>
 * <p>
 * How close your plan is to your budgeted amount or to the free tier limits
 * </p>
 * </li>
 * <li>
 * <p>
 * Your usage-to-date, including how much you've used of your Reserved Instances (RIs)
 * </p>
 * </li>
 * <li>
 * <p>
 * Your current estimated charges from Amazon Web Services, and how much your predicted usage will accrue in charges by
 * the end of the month
 * </p>
 * </li>
 * <li>
 * <p>
 * How much of your budget has been used
 * </p>
 * </li>
 * </ul>
 * <p>
 * Amazon Web Services updates your budget status several times a day. Budgets track your unblended costs,
 * subscriptions, refunds, and RIs. You can create the following types of budgets:
 * </p>
 * <ul>
 * <li>
 * <p>
 * <b>Cost budgets</b> - Plan how much you want to spend on a service.
 * </p>
 * </li>
 * <li>
 * <p>
 * <b>Usage budgets</b> - Plan how much you want to use one or more services.
 * </p>
 * </li>
 * <li>
 * <p>
 * <b>RI utilization budgets</b> - Define a utilization threshold, and receive alerts when your RI usage falls below
 * that threshold. This lets you see if your RIs are unused or under-utilized.
 * </p>
 * </li>
 * <li>
 * <p>
 * <b>RI coverage budgets</b> - Define a coverage threshold, and receive alerts when the number of your instance hours
 * that are covered by RIs fall below that threshold. This lets you see how much of your instance usage is covered by a
 * reservation.
 * </p>
 * </li>
 * </ul>
 * <p>
 * Service Endpoint
 * </p>
 * <p>
 * The Amazon Web Services Budgets API provides the following endpoint:
 * </p>
 * <ul>
 * <li>
 * <p>
 * https://budgets.amazonaws.com
 * </p>
 * </li>
 * </ul>
 * <p>
 * For information about costs that are associated with the Amazon Web Services Budgets API, see <a
 * href="https://aws.amazon.com/aws-cost-management/pricing/">Amazon Web Services Cost Management Pricing</a>.
