How does Scala support polyglot microservices ecosystems?

Scala integrates into polyglot systems via JVM interoperability and standardized APIs.

Scala runs on the JVM, enabling seamless integration with Java, Kotlin, and other JVM languages. Microservices communicate via REST, gRPC, or messaging systems. API contracts are defined using OpenAPI or Protobuf to ensure cross-language compatibility. This enables heterogeneous system design while maintaining consistency.
