/**
* Client for accessing Amazon CloudWatch Events. All service calls made using
* this client are blocking, and will not return until the service call
* completes.
*
*
* Amazon CloudWatch Events helps you to respond to state changes in your AWS
* resources. When your resources change state they automatically send events
* into an event stream. You can create rules that match selected events in the
* stream and route them to targets to take action. You can also use rules to
* take action on a pre-determined schedule. For example, you can configure
* rules to:
*
*
* - Automatically invoke an AWS Lambda function to update DNS entries when an
* event notifies you that Amazon EC2 instance enters the running state.
* - Direct specific API records from CloudTrail to an Amazon Kinesis stream
* for detailed analysis of potential security or availability risks.
* - Periodically invoke a built-in target to create a snapshot of an Amazon
* EBS volume.
*
*
* For more information about Amazon CloudWatch Events features, see the Amazon
* CloudWatch Developer Guide.
