Java and Jakarta EE applications can run on Nanos Unikernel without any code changes or JVM modifications, enabling a simpler and more efficient deployment model. A proof of concept demonstrates Quarkus with IBM Semeru Runtime deployed as a unikernel image on AWS Graviton2 (ARM64) via the Nitro hypervisor. The unikernel stack eliminates the guest OS and container runtime layers, reducing boot time, memory footprint, and attack surface. The same Nanos image previously run on Oracle Cloud Infrastructure was deployed unchanged on AWS, confirming hypervisor and cloud-provider independence. The PoC is fully reproducible via a public GitHub Actions workflow.
