Azure Migrate Application and Code Assessment for Java has discovered the following issues:

1. Upgrade to JDK 21
2. Migrate from Spring RabbitMQ to Azure Service Bus
3. Migrate from AWS S3 to Azure Blob Storage

Additional details below.

Upgrade required: JDK 8 to JDK 21
The application uses JDK 8. It is strongly recommended to upgrade the application dependency to JDK 21.

Migrate from Spring RabbitMQ AMQP to Azure Service Bus
The application uses Spring RabbitMQ based on Spring AMQP in code. To migrate a Java application that uses Spring RabbitMQ to Azure, you can follow these recommendations:

Provision Azure Service Bus: Replace RabbitMQ with Azure Service Bus, a fully managed messaging service that offers reliable message queuing and publish/subscribe capabilities.

Update the application's messaging connection details: Modify the Java application's configuration updating the connection information and message queues/topics.

Configure Azure Service Bus queues/topics: Create appropriate queues or topics in Azure Service Bus to align with your application's messaging requirements. Configure access control and security settings as needed.

Migrate from AWS S3 to Azure Blob Storage
The application contains AWS S3 dependency usage. Consider using Azure Blob Storage instead.

Provision Azure Blob Storage: Create an Azure Blob Storage account in the Azure portal. Choose the appropriate storage tier (Hot, Cool, or Archive) based on your application's data access patterns and cost considerations.
Update application code: Modify the Java application's code to replace AWS SDK calls with the equivalent Azure Storage SDK calls for Azure Blob Storage. Update the code to authenticate and interact with Azure Blob Storage using the Azure SDK for Java.

Map S3 functionality to Azure Blob Storage: Understand the differences between AWS S3 and Azure Blob Storage, and adjust your application logic accordingly. Map S3 concepts (buckets, objects, permissions, etc.) to their Azure Blob Storage equivalents (containers, blobs, shared access signatures, etc.).

Migrate data from S3 to Azure Blob Storage: Plan and execute the migration of your data from AWS S3 to Azure Blob Storage. You can use Azure Storage Data Transfer Tool, AzCopy, or other migration tools to copy the data from S3 buckets to Azure Blob Storage containers.

Update access permissions: Adjust the access permissions and policies in Azure Blob Storage to match your application's requirements. Azure provides various options for controlling access, including shared access signatures (SAS), Azure AD authentication, and role-based access control (RBAC).

Validate functionality and performance: Thoroughly test the updated application to ensure that it can read from and write to Azure Blob Storage correctly. Validate the performance of data transfer and any other operations to ensure they meet your application's requirements.
