/**
* Client for accessing AWSHealth. All service calls made using this client are blocking, and will not return until the
* service call completes.
* <p>
* <fullname>AWS Health</fullname>
* <p>
* The AWS Health API provides programmatic access to the AWS Health information that is presented in the <a
* href="https://phd.aws.amazon.com/phd/home#/">AWS Personal Health Dashboard</a>. You can get information about events
* that affect your AWS resources:
* </p>
* <ul>
* <li>
* <p>
* <a>DescribeEvents</a>: Summary information about events.
* </p>
* </li>
* <li>
* <p>
* <a>DescribeEventDetails</a>: Detailed information about one or more events.
* </p>
* </li>
* <li>
* <p>
* <a>DescribeAffectedEntities</a>: Information about AWS resources that are affected by one or more events.
* </p>
* </li>
* </ul>
* <p>
* In addition, these operations provide information about event types and summary counts of events or affected
* entities:
* </p>
* <ul>
* <li>
* <p>
* <a>DescribeEventTypes</a>: Information about the kinds of events that AWS Health tracks.
* </p>
* </li>
* <li>
* <p>
* <a>DescribeEventAggregates</a>: A count of the number of events that meet specified criteria.
* </p>
* </li>
* <li>
* <p>
* <a>DescribeEntityAggregates</a>: A count of the number of affected entities that meet specified criteria.
* </p>
* </li>
* </ul>
* <p>
* The Health API requires a Business or Enterprise support plan from <a
* href="http://aws.amazon.com/premiumsupport/">AWS Support</a>. Calling the Health API from an account that does not
* have a Business or Enterprise support plan causes a <code>SubscriptionRequiredException</code>.
* </p>
* <p>
* For authentication of requests, AWS Health uses the <a
* href="http://docs.aws.amazon.com/general/latest/gr/signature-version-4.html">Signature Version 4 Signing Process</a>.
* </p>
* <p>
* See the <a href="http://docs.aws.amazon.com/health/latest/ug/what-is-aws-health.html">AWS Health User Guide</a> for
* information about how to use the API.
* </p>
* <p>
* <b>Service Endpoint</b>
* </p>
* <p>
* The HTTP endpoint for the AWS Health API is:
* </p>
* <ul>
* <li>
* <p>
* https://health.us-east-1.amazonaws.com
* </p>
* </li>
* </ul>
