Migrating from AWS App Runner to Amazon ECS Express Mode In this post, I’ll show you how to migrate your containerized applications from AWS App Runner to Amazon ECS Express Mode using a blue/green deployment strategy. This approach helps to eliminate downtime during the migration, allowing you to shift traffic gradually and roll back if needed. You’ll learn how to set up ECS Express Mode and configure custom domain.

⚠️ Deprecation warning!

AWS App Runner is deprecated and will stop accepting new customers from April 1, 2026.

Announcing Model Context Protocol (MCP) Server for AWS Price List Today, AWS announces the release of the Model Context Protocol (MCP) server for AWS Price List, now available in the AWS Labs GitHub repository. The MCP server provides AI agents with real-time access to AWS product data, availability information and pricing details, including on-demand, reserved, and savings plans. With this launch, you can leverage AI assistants, including Amazon Q Developer CLI, and Claude Desktop, to retrieve AWS product and pricing information, compare pricing options across regions, and make data-driven decisions about AWS service selections - all through natural language conversations. You can download and integrate the open-source server with your preferred MCP-compatible AI assistant. The server connects securely to the AWS Price List using standard AWS credentials with minimal configuration required. To get started, visit the AWS Labs GitHub repository.

🆕 AWS launches Model Context Protocol (MCP) server for real-time access to AWS pricing data via AI agents. Available on GitHub, it enables natural language comparisons and decisions on AWS services, integrating easily with AI assistants like Amazon Q and Claude.

Anthropic's Claude 4 foundation models now in Amazon Bedrock The 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.

🆕 Anthropic's advanced Claude Opus 4 and Sonnet 4 models are now in Amazon Bedrock, offering top coding, AI agent capabilities, and hybrid reasoning. Integrate via Amazon Bedrock API/SDK. Visit AWS News Blog for region details and pricing.

Building Super Slim Containerized Lambdas on AWS - Revisited Personal web page and blog.

I just published a new blog post about slim Dockerized AWS Lambda functions:

Amazon EC2 now supports more bandwidth and jumbo frames to select destinations Amazon 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.

🆕 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.
