Amazon EC2 C7g instances are now available in AWS Canada West (Calgary) Region

Starting today, Amazon Elastic Compute Cloud (Amazon EC2) C7g instances are available in the AWS Canada West (Calgary) region. These instances are powered by AWS Graviton3 processors that provide up to 25% better compute performance compared to AWS Graviton2 processors, and built on top of the the AWS Nitro System, a collection of AWS designed innovations that deliver efficient, flexible, and secure cloud services with isolated multi-tenancy, private networking, and fast local storage.\n Amazon EC2 Graviton3 instances also use up to 60% less energy to reduce your cloud carbon footprint for the same performance than comparable EC2 instances. For increased scalability, these instances are available in 9 different instance sizes, including bare metal, and offer up to 30 Gbps networking bandwidth and up to 20 Gbps of bandwidth to the Amazon Elastic Block Store (EBS). To learn more, see Amazon EC2 C7g. To explore how to migrate your workloads to Graviton-based instances, see AWS Graviton Fast Start program and Porting Advisor for Graviton. To get started, see the AWS Management Console.

Amazon EC2 M7gd instances are now available in Middle East (UAE) Region

Starting today, Amazon Elastic Compute Cloud (Amazon EC2) M7gd instances with up to 3.8 TB of local NVMe-based SSD block-level storage are available in Middle East (UAE) region.\n These Graviton3-based instances with DDR5 memory are built on the AWS Nitro System and are a great fit for applications that need access to high-speed, low latency local storage, including those that need temporary storage of data for scratch space, temporary files, and caches. They have up to 45% improved real-time NVMe storage performance than comparable Graviton2-based instances. Graviton3-based instances also use up to 60% less energy for the same performance than comparable EC2 instances, enabling you to reduce your carbon footprint in the cloud. M7gd instances are now available in the following AWS regions: US East (N. Virginia, Ohio), US West (Oregon, N. California), Europe (Spain, Stockholm, Ireland, Frankfurt, Paris), Asia Pacific (Tokyo, Mumbai, Singapore, Sydney), South America (São Paulo), and Middle East (UAE). To learn more, see Amazon EC2 M7gd instances. To get started, see the AWS Management Console.

Amazon Nova expands Tool Choice options for Converse API

Amazon Nova now supports expanded Tool Choice parameter options in the Converse API, enhancing developers’ control over model interactions with tools. Today, developers already use the Converse API to create sophisticated conversational applications, such as customized chat bots to maintain conversations over multiple turns. With this update, Nova adds support for ‘Any’ and ‘Tool’ modes in addition to the existing ‘Auto’ mode support, enabling developers to use all three different modes.\n

Auto leaves tool selection entirely to Nova’s discretion, whether to call a tool or generate text instead. Auto is useful in use cases like chatbots and assistants where you may need to ask the user for more information, and is the current default.

Any prompts Nova to return at least one tool call, from the list of tools specified, while allowing it to choose which tool to use. Any is particularly useful in machine to machine interactions where your downstream components may not understand natural language but might be able to parse a schema representation.

Tool enable developers to request a specific tool to be returned by Nova. Tool is particularly useful in forcing a structured output by having a tool that has the return type as your desired output schema.

To learn about expanded Tool Choice parameter support in Amazon Nova’s Converse API, see the Amazon Nova user guide. Learn more about Amazon Nova foundation models at the Amazon Nova product page. You can get started with Amazon Nova foundation models in Amazon Bedrock from the Amazon Bedrock console.
