You can now monitor bytes, packets, active connections and several other metrics for NAT Gateways via CloudWatch console and AWS CLI. You can setup CloudWatch Alarms to notify you of crossing thresholds. All metrics are provided with a 1 min frequency. For more information about the metrics, see  Monitoring Your NAT Gateway with Amazon CloudWatch.

If you are using Amazon Route 53 as your public, authoritative DNS, you will now have the capability to easily log DNS queries received by Amazon Route 53 through integration with CloudWatch Logs. This capability makes it easier to debug issues, conduct security audits, and run business analytics. With near real-time log delivery, customers can react quickly to events, and the power of CloudWatch Logs makes it easy to search, export, or archive your query logs. 

We are pleased to announce the launch of a new Network Load Balancer for the Elastic Load Balancing service designed to handle millions of requests per second while maintaining ultra-low latencies. This new load balancer is optimized to handle volatile traffic patterns while using a single static IP address per Availability Zone. Network Load Balancer operates at the connection level (Layer 4), routing connections to Amazon EC2 instances and containers within Amazon Virtual Private Cloud (Amazon VPC) based on IP protocol data. It also preserves the client side source IP, allowing applications to see the IP address of the client that can then be used by applications for further processing. 

Amazon Glacier is a secure, durable, and extremely low-cost storage service for data archiving and online backup. Today, AWS made the Amazon Glacier console available in Japanese and Korean languages. The availability of Glacier console in five languages—it was already available in English, French, and Chinese—reduces the need to have multilingual staff that can manage and administer Glacier vaults and archives. 

Your analytics and search applications can now benefit from support for Elasticsearch 5.5 and Kibana 5.5 in Amazon Elasticsearch Service. Elasticsearch is a popular search and analytics engine for log analytics, full text search, application monitoring, and more. Amazon Elasticsearch Service delivers Elasticsearch’s easy-to-use APIs and real-time capabilities along with the availability, scalability, and security required by production workloads. 

You can now use the new dynamic range compression (DRC) tag to enhance the volume of certain sounds in your audio file. The sounds in an audio file range from softer sounds to louder, depending on the text, the language, and the voice. For example, conflicting ambient sounds such as those of a moving vehicle can often mask the softer sounds, making the audio track difficult to hear clearly. To enhance the clarity of the Text-to-Speech output, simply use the SSML tag “DRC” to mark the text input. This is especially suitable for audio to be used in noisy environments. DRC is a boolean parameter (meaning that it’s either on or off) that can be used with any Amazon Polly supported voice or language. It can be used for an entire section of text, or only for a few words, based on your needs. 

Amazon EC2 Container Service (Amazon ECS) now supports the Network Load Balancer for load balancing TCP traffic to container tasks and services.
