AWS Transform adds Aurora PostgreSQL cross-region deployment in 7 new Regions

AWS Transform for Windows modernization now supports deploying converted Aurora PostgreSQL clusters to different AWS Regions than the source SQL Server instance. This update, available in seven additional Regions, allows engineers to specify a target Region during the transformation plan to meet data residency or disaster recovery goals. The tool simultaneously updates dependent .NET application code, including connection strings and data-access layers, to ensure compatibility with the new PostgreSQL endpoints.

  • Enables geographic separation of source SQL Server and target Aurora PostgreSQL during modernization
  • Supports compliance and DR by allowing cross-region deployment of transformed databases
  • Automates .NET application updates for PostgreSQL connectivity and ORM compatibility
  • Available in seven additional AWS Regions to broaden modernization coverage

Fleet impact: For DBAs managing mixed Oracle/PostgreSQL estates, this facilitates compliant SQL Server-to-Aurora migrations by decoupling source and target regions. Verify cross-region latency tolerances and ensure RDS parameter groups are tuned for the specific target Region's Aurora PostgreSQL version.

AWS previews Well-Architected Agent for automated infra analysis

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 focused on cost, security, performance, and reliability. Additionally, it offers specific remediation steps and can review infrastructure-as-code templates prior to deployment.

  • Automates environment checks against AWS Well-Architected pillars
  • Prioritizes recommendations by cost, security, performance, and reliability
  • Provides actionable remediation steps rather than just findings
  • Integrates IaC review to catch issues before deployment
  • Currently available in preview mode

AWS Lambda durable functions now live in GovCloud (US) Regions

AWS has expanded Lambda durable functions to GovCloud (US-West and US-East), bringing checkpointing and automatic recovery capabilities to regulated environments. These primitives allow developers to build reliable multi-step workflows and AI pipelines without incurring compute charges during wait periods. The update enables government and regulated industries to orchestrate complex processes while maintaining strict compliance standards.

  • Enables checkpointing and auto-recovery for multi-step apps in GovCloud
  • New primitives like 'step' and 'wait' pause execution without compute charges
  • Supports regulated industries building AI workflows and order processing
  • Available in both US-West and US-East GovCloud regions

AWS Transform adds Azure-to-AWS .NET code conversion

AWS has released general availability for a new feature in AWS Transform that automatically converts Azure SDK calls to AWS SDK equivalents in .NET applications. The tool scans submitted source code to identify Azure services, such as Cosmos DB or Functions, and maps them to corresponding AWS resources like DynamoDB or Lambda. Users can review and adjust the suggested conversion mappings in the assessment report before executing the final modernization plan.

  • Automates migration of Azure-native .NET apps to AWS by swapping SDK calls
  • Maps specific services like Azure Functions/Cosmos DB to Lambda/DynamoDB
  • Provides an assessment report allowing manual adjustment of conversion logic
  • Targets cloud-native codebases to reduce manual refactoring effort

AWS tests EU Sovereign Cloud isolation from global backbone

AWS will disconnect its European Sovereign Cloud from the global network backbone on October 24. The exercise relies exclusively on EU-resident staff and local infrastructure to demonstrate operational independence. While AWS states that neither severed system is operation-critical, industry experts remain skeptical about whether this test adequately addresses customer sovereignty concerns.

  • AWS validates EU cloud autonomy by cutting global backbone links for several hours
  • Operations during the test rely strictly on EU-based personnel and local hardware
  • AWS claims the isolated systems are non-critical, but customer trust remains unproven
  • Practitioners question if a temporary severance truly proves sovereign capability
