This ensures that sensitive data can only be decrypted and viewed by certain components or services in your application stack. Field-level encryption is easy to setup. Simply configure the fields that have to be further encrypted by CloudFront using the public keys you specify and you can reduce attack surface for your sensitive data.

* `Aws\RDS` - 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.

Once cataloged, your data is immediately searchable, queryable, and available for ETL. AWS Glue generates the code to execute your data transformations and data loading processes. AWS Glue generates Python code that is entirely customizable, reusable, and portable. Once your ETL job is ready, you can schedule it to run on AWS Glue's fully managed, scale-out Spark environment. AWS Glue provides a flexible scheduler with dependency resolution, job monitoring, and alerting. AWS Glue is serverless, so there is no infrastructure to buy, set up, or manage.

Using Migration Hub will provide you with a single screen that shows the migration progress of all the resources in the application. This allows you to quickly get progress updates across all of your migrations, easily identify and troubleshoot any issues, and reduce the overall time and effort spent on your migration projects. Migration Hub is available to all AWS customers at no additional charge. You only pay for the cost of the migration tools you use, and any resources being consumed on AWS.

Using the cache refresh feature in this update, the customer can trigger an on-demand scan of the keys in their S3 bucket and refresh the file namespace cached on the gateway. It takes as an input the fileShare ARN and refreshes the cache for only that file share. Additionally there is new functionality on file gateway that allows you configure what squash options they would like on their file share, this allows a customer to configure their gateway to not squash root permissions. This can be done by setting options in NfsOptions for CreateNfsFileShare and UpdateNfsFileShare APIs.

## 3.24.9 - 2017-03-28

* `Aws\Batch` - Customers can now provide a retryStrategy as part of the RegisterJobDefinition and SubmitJob API calls. The retryStrategy object has a number value for attempts. This is the number of non successful executions before a job is considered FAILED. In addition, the JobDetail object now has an attempts field and shows all execution attempts.
* `Aws\EC2` - Customers can now tag their Amazon EC2 Instances and Amazon EBS Volumes at the time of their creation. You can do this from the EC2 Instance launch wizard or through the RunInstances or CreateVolume APIs. By tagging resources at the time of creation, you can eliminate the need to run custom 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.
