AWS has launched a preview of the Well-Architected Agent, an AI-driven service that evaluates cloud environments against established best practices. The tool generates prioritized recommendations covering cost, security, performance, and reliability, while also suggesting specific remediation steps. It additionally offers pre-deployment reviews for infrastructure-as-code templates.

  • Automates Well-Architected framework checks across cost, security, performance, and reliability
  • Provides prioritized remediation steps rather than just high-level findings
  • Integrates pre-deployment IaC review to catch issues before provisioning
  • Currently in preview status, indicating potential API or feature changes
  • Reduces manual audit overhead for complex AWS environments

AWS plans to operate its European Sovereign Cloud in isolation from the global network backbone on October 24. The exercise relies on EU-based personnel and regional hardware to demonstrate autonomous capability. While AWS states the disconnected systems are not operation-critical, industry experts remain skeptical about the test's relevance to customer needs.

  • Test involves severing connectivity to the AWS Global Network backbone
  • Operations managed exclusively by EU residents and local infrastructure
  • AWS claims disconnected components are not operation-critical
  • Practitioners question if the exercise addresses actual sovereignty concerns

AWS has expanded Lambda's built-in recursive loop detection to cover invocations triggered by Amazon EventBridge Custom event buses. This feature automatically halts execution when a misconfiguration or code defect causes a Lambda Event Function to recursively trigger itself via EventBridge rules. The update aims to prevent runaway workloads and unexpected billing spikes by stopping infinite loops at the source.

  • Prevents unexpected costs from recursive Lambda-EventBridge invocation loops
  • Automatically stops runaway workloads triggered by Custom event bus misconfigurations
  • Feature is enabled by default on AWS accounts, requiring no manual setup
  • Protects automation workflows and scheduled tasks from code defects

AWS ARC Region Switch gains SSM, Lambda payloads, and health checks

Amazon Application Recovery Controller's Region Switch now supports four new capabilities for orchestrating multi-Region failovers. These include an AWS Systems Manager Run Command execution block, custom action Lambda payloads, service quota parity checks, and a wait-for-target-group-health feature for compute scaling. The updates allow for more complex automation and validation steps during the recovery process.

  • Execute SSM Run Command actions on managed instances directly within failover plans
  • Attach custom payloads to Lambda execution blocks for tailored recovery logic
  • Automatically verify service quota parity across Regions before switching
  • Pause scaling actions until target group health checks pass successfully

AWS Lambda durable functions arrive in GovCloud (US)

AWS has expanded Lambda durable functions to the GovCloud (US-West and US-East) regions. This feature adds checkpointing and pause/resume primitives to the Lambda event handler, enabling reliable orchestration of multi-step workflows and AI tasks. It allows regulated industries to build complex applications with automatic failure recovery and no compute charges during wait states, all within strict compliance boundaries.

  • Adds 'step' and 'wait' primitives to Lambda handlers for checkpointing
  • Enables automatic recovery from failures in multi-step workflows
  • Pauses executions without incurring compute charges for on-demand functions
  • Supports AI-assisted tasks and complex orchestration in regulated environments
