### Service Client Updates
* `service/snowball`: Updates service API
  * Snowball job states allow customers to track the status of the Snowball job. We are launching a new Snowball job state "WithSortingFacility"!

* `service/elasticloadbalancingv2`: Updates service API and documentation
* `service/rds`: Updates service API and documentation
  * Read Replicas for Amazon RDS for MySQL, MariaDB, and PostgreSQL now support Multi-AZ deployments.Amazon RDS Read Replicas enable you to create one or more read-only copies of your database instance within the same AWS Region or in a different AWS Region. Updates made to the source database are asynchronously copied to the Read Replicas. In addition to providing scalability for read-heavy workloads, you can choose to promote a Read Replica to become standalone a DB instance when needed.Amazon RDS Multi-AZ Deployments provide enhanced availability for database instances within a single AWS Region. With Multi-AZ, your data is synchronously replicated to a standby in a different Availability Zone (AZ). In case of an infrastructure failure, Amazon RDS performs an automatic failover to the standby, minimizing disruption to your applications.You can now combine Read Replicas with Multi-AZ as part of a disaster recovery strategy for your production databases. A well-designed and tested plan is critical for maintaining business continuity after a disaster. Since Read Replicas can also be created in different regions than the source database, your Read Replica can be promoted to become the new production database in case of a regional disruption.You can also combine Read Replicas with Multi-AZ for your database engine upgrade process. You can create a Read Replica of your production database instance and upgrade it to a new database engine version. When the upgrade is complete, you can stop applications, promote the Read Replica to a standalone database instance and switch over your applications. Since the database instance is already a Multi-AZ deployment, no additional steps are needed.For more information, see the Amazon RDS User Guide.

	tagging scripts after resource creation. In addition, you can now set
	resource-level permissions on the CreateVolume, CreateTags, DeleteTags, and
	the RunInstances APIs. This allows you to implement stronger security
	policies by giving you more granular control over which users and groups
	have access to these APIs. You can also enforce the use of tagging and
	control what tag keys and values are set on your resources. When you combine
	tag usage and resource-level IAM policies together, you can ensure your
	instances and volumes are properly secured upon creation and achieve more
	accurate cost allocation reporting. These new features are provided at no
	additional cost.
