AWS X-Ray helps developers analyze and debug production, distributed applications, such as those built using a microservices architecture. With X-Ray, you can understand how your application and its underlying services are performing to identify and troubleshoot the root cause of performance issues and errors. X-Ray provides an end-to-end view of requests as they travel through your application, and shows a map of your application’s underlying components. You can use X-Ray to analyze both applications in development and in production, from simple three-tier applications to complex microservices applications consisting of thousands of services.

Amazon API Gateway now integrates with the AWS Marketplace to help API owners monetize their API and meter usage for their API products, without writing any code. 

You can now use AWS CloudFormation to provision the following AWS resources. See the release history for more detail. 

EC2 instances in Amazon Virtual Private Cloud (VPC) now offer native support for the IPv6 protocol. IPv6 can be enabled for existing and new VPCs through the AWS management console, API/SDK and CLI. Customers can use IPv6 on EC2 instances to access Internet resources as well as on-premise applications using Direct Connect. This enables numerous use cases such as hosting public services and meeting IPv6 compliance requirements.

Lambda@Edge, now in Preview, allows you to write functions deployed to the AWS network of Edge locations in response to CloudFront. This new feature allows you to customize or personalize content for your end users close to where they’re located, minimizing network latency. For instance, you can modify HTTP headers to personalize your application for each user, implement custom authentication or encryption logic right at the edge, detect and group users by device, support legacy devices by reformatting content on the viewer response, and much more.

Custom authorizers on Amazon API Gateway can now return additional fields in their authorization response.

You can now add documentation to your methods and resources for your APIs built using Amazon API Gateway, making it easy for your API consumers to understand your API. You can add documentation for your API directly using the API Gateway console, CLI, and SDK, or simply specify it using documentation tags within the Swagger definition for the API. You can also reuse documentation across common aspects of your API. For example, you can author standard error documentation just one time, and use it in multiple API responses as without duplicating the actual content, making it faster to document your APIs and eliminating “copy-paste” errors that can arise with duplicated strings. Once your documentation is published as part of an API stage, you can export it using the Swagger export feature and make it available in your developer portal. 

The price reductions for Amazon EC2 C4, M4 & T2 instances across all AWS regions, announced on November 14th, 2016 , are now effective.

You can now receive notification and remediation guidance when AWS is experiencing events that may impact you. Available to all AWS customers, AWS Personal Health Dashboard provides a personalized view into the performance and availability of the AWS services you are using, as well as alerts that are automatically triggered by changes in the health of those services.

Amazon AppStream 2.0 is now generally available. AppStream 2.0 is a fully managed, secure application streaming service that allows you to stream desktop applications from AWS to any device, without rewriting them. AppStream 2.0 provides users with instant-on access to the applications they need, and a responsive, fluid user experience running in an HTML5 web browser.
