You are migrating 30 Spring Boot microservices (packaged as JARs) from on-premises VMs. The apps use Spring Cloud Config (Git backend), Netflix Eureka for service discovery, MySQL, and Redis. You must minimize code changes and adopt managed services. What should you recommend?

This option is correct because Azure Spring Apps (ASA) is specifically designed for Spring Boot applications, minimizing code changes. The Standard tier supports the required features. ASA's managed Config Server can directly use the existing Git repository, and its built-in Service Discovery integrates with Eureka. Azure Database for MySQL Flexible Server and Azure Cache for Redis are managed services that directly replace the existing data stores. Service Connector simplifies binding applications to these services. The other options are less suitable: Containerizing for AKS would require significant refactoring to replace Spring Cloud Config and Eureka with Kubernetes-native alternatives. Azure App Service for Linux with Java doesn't offer managed Config Server or Eureka integration, and keeping these on-premises defeats the purpose of migration. Azure Functions is a serverless compute service, not ideal for long-running microservices, and replacing MySQL with Cosmos DB would require significant data model changes. Azure Spring Apps Enterprise tier is overkill if the Standard tier meets requirements, and replacing Redis with Azure Service Bus queues is a functional change not requested and would require code changes.
