The first quarter of 2026 has brought significant advancements in AWS serverless technology. This recap highlights the most impactful launches and features that developers should not overlook.
Understanding Serverless with Mama J
Eric Johnson shared a relatable explanation of serverless computing with his mother, affectionately known as Mama J. He clarified how AWS Lambda allows developers to run code only when needed, automatically scaling without the burden of server management.
AI-Powered Tools for Developers
AWS is enhancing serverless development with AI-driven tools. These include:
- Model Context Protocol (MCP) servers
- Anthropic Claude plugins
- Kiro Powers
These tools offer contextual guidance throughout the development lifecycle, aiding in architecture decisions and deployment automation.
Serverless Patterns Collection
The open-source Serverless Patterns Collection now features a direct download option for pattern .zip files, allowing developers to easily access and clone various serverless patterns.
Building Durable Applications
AWS Lambda durable functions enable the creation of fault-tolerant applications using familiar programming patterns. Developers can write multi-step workflows in languages like Python and TypeScript, focusing on business logic while managing costs effectively.
New Features in AWS Lambda
Recent updates to AWS Lambda include:
- Support for .NET 10 runtime, enhancing performance and startup times
- Visibility of Availability Zone (AZ) metadata in execution environments, aiding in AZ-aware routing
- Increased maximum payload size from 256 KB to 1 MB for various services
Amazon Bedrock Expansions
Amazon Bedrock has expanded its model offerings, including new open-weight models and support for AI agents through the AgentCore infrastructure layer. This allows for secure deployment and operation of AI agents with flexibility in tool selection.
Enhanced Testing and Monitoring
AWS Step Functions now features an enhanced TestState API for validating workflows before deployment, reducing the risk of production issues. Additionally, Amazon EventBridge Scheduler provides resource count metrics for better quota management.
Data Replication and Integration
Amazon DynamoDB now supports data replication across multiple AWS accounts and regions, enhancing resiliency and security. Furthermore, Amazon ECS Managed Instances can integrate with EC2 Capacity Reservations, ensuring capacity availability for container workloads.
Join the Community
For ongoing discussions and insights, a weekly livestream is held every Tuesday at 11 AM PT, covering serverless technologies. Developers can also explore resources available on the Serverless landing page for tutorials, case studies, and more.
