aws.amazon.comAnthropic's Claude 4 foundation models now in Amazon BedrockThe next generation of Anthropic's Claude models, Claude Opus 4 and Claude Sonnet 4, are now available in Amazon Bedrock, representing significant advancements in AI capabilities. These models excel at coding, enable AI agents to analyze thousands of data sources, execute long-running tasks, write high-quality content, and perform complex actions. Both Opus 4 and Sonnet 4 are hybrid reasoning models offering two modes: near-instant responses and extended thinking for deeper reasoning. Claude Opus 4: Opus 4 is Anthropic’s most powerful Claude model to date and Anthropic’s benchmarks show it is the best coding model available, excelling at autonomously managing complex, multi-step tasks with accuracy. It can independently break down abstract projects, plan architectures, and maintain high code quality throughout extended tasks. Opus 4 is ideal for powering agentic AI applications that require uncompromising intelligence for orchestrating cross-functional enterprise workflows or handling a major code migration for a large codebase. Claude Sonnet 4: Sonnet 4 is a midsize model designed for high-volume use cases and can function effectively as a task-specific sub-agent within broader AI systems. It efficiently handles specific tasks like code generation, search, data analysis, and content synthesis, making it well suited for production AI applications requiring a balance of quality, costeffectiveness, and responsiveness. You can now use both Claude 4 models in Amazon Bedrock. To get started, visit the Amazon Bedrock console. Integrate it into your applications using the Amazon Bedrock API or SDK. For more information including region availability, see the AWS News Blog, Anthropic's Claude in Amazon Bedrock product page, and the Amazon Bedrock pricing page.

🆕 Amazon EC2 now supports full bandwidth for inter-region VPC peering and AWS Direct Connect, plus jumbo frames up to 8500 Bytes for cross region VPC peering, boosting data transfer speeds. Available in all commercial regions. #AWS #AmazonEc2 #AwsGovcloudUs

aws.amazon.comAmazon EC2 now supports more bandwidth and jumbo frames to select destinationsAmazon EC2 now supports up to the full EC2 instance bandwidth for inter-region VPC peering traffic and to AWS Direct Connect. Additionally, EC2 supports jumbo frames up to 8500 Bytes for cross region VPC peering. Before today, the egress bandwidth for EC2 instances was limited to 50% of the aggregate bandwidth limit for instances with 32 or more vCPUs, and 5 Gbps for smaller instances. Cross region peering supported up to 1500 bytes. Now, customers can send bandwidth from EC2 between regions or towards AWS Direct Connect at the full instance baseline specification or 5Gbps, whichever is greater and customers can use jumbo frames across regions for peered VPCs. Customers transferring data between regions or from EC2 to their on-premises network via AWS Direct Connect now have access to the full instance bandwidth capabilities. Before today, customers sending traffic to any destination not in the same region had a lower bandwidth limit. With this change, the lower limit has been removed for destinations between AWS regions and to on-premises through AWS Direct Connect, allowing for faster transfers. Additionally, supporting jumbo frames for peering makes sending large volumes of data faster than before. This capability is available in all AWS commercial regions, the AWS GovCloud (US) Regions, and the Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD. Customers can take advantage of this capability without any additional changes. To learn more about EC2 bandwidth capabilities, please review our user guide.

🆕 The AWS Management Console now supports simultaneous sign-in for multiple AWS accounts #AWS #AwsManagementConsole

aws.amazon.comThe AWS Management Console now supports simultaneous sign-in for multiple AWS accountsToday, AWS announces multi-sesssion support which enables customers to access multiple AWS accounts in the AWS Console. Customers can sign-in to up to 5 sessions in a single browser, and this can be any combination of root, IAM, or federated roles in different accounts or in the same account. Customer applications scale multiple accounts following AWS best-practice guidelines. They often use accounts for different environments such as development, testing, production, and compare resource configurations and statuses across multiple accounts for troubleshooting application issues and other application related jobs. Before this launch, the AWS Console supported one account sign-in at a time, and customers used mechanism such as signing-in accounts in different browsers or installing third-party browser plugins to access multiple accounts in different browsers. Using multi-session capability in the AWS Console, customers can sign-in to their different AWS accounts and manage their resources in a single browser. Multi-session support is available in Commercial Regions. Try it today by signing in to the AWS Console, selecting the account menu, and selecting “Turn on multi-session”. You can opt out at any time from the account menu. Visit AWS Console documentation to learn more.
