AWS Transform can now convert Azure SDK code in .NET apps to AWS SDK code

AWS has made code conversion from the Azure SDK to the AWS SDK generally available in AWS Transform, according to an announcement posted on Oct. 16. The company presents the capability as a quicker way to move cloud-native .NET applications built for Microsoft Azure onto AWS. According to AWS, the .NET modernization agent in AWS Transform locates code that calls Azure services and rewrites it to use the corresponding AWS services.

AWS lists four supported conversions: Azure Functions are rewritten as AWS Lambda functions, Azure Blob Storage code is moved to Amazon S3, and Azure Queue Storage code is moved to Amazon SQS, while converting Azure Cosmos DB code to Amazon DynamoDB is offered as a preview. The user guide states that only these listed services are converted and suggests AWS Transform custom or an AI code companion such as Kiro for other services. AWS also notes that the feature handles application code only and does not migrate cloud infrastructure.

According to AWS, the service detects the Azure SDK in submitted source code and lays out conversion options in its assessment report and modernization plan, which users can accept or adjust before the modernization runs. AWS says it then checks that the changes are incorporated into the transformed code. The documentation describes conversion as automatic for eligible modern .NET applications, with behavior adjustable through agent chat, edits to the plan or a steering document, for example to skip some or all conversions, set naming conventions, change comment verbosity or point Blob Storage code at DynamoDB instead of S3.

Code that has no equivalent on AWS is flagged rather than converted: the user guide says it is marked with TODO comments, left as stubbed code or recorded in a Next Steps markdown file produced by AWS Transform. AWS says AWS Transform is offered in eight AWS Regions, namely Frankfurt and London in Europe, Mumbai, Tokyo, Seoul and Sydney in Asia Pacific, as well as Canada (Central) and US East (N. Virginia).
