Technical Requirements

Oracle Autonomous Linux operates within the Oracle Cloud Infrastructure (OCI) environment, leveraging OCI's flexible compute resources. Specific minimum hardware requirements are therefore dependent on the chosen OCI compute instance shape.

• RAM: Requirements vary based on OCI compute instance size. For monitoring OCI instances, the Oracle Management Agent recommends a minimum of 500 MiB of memory.
• Processor: Supports 64-bit Intel and AMD (x86_64) and 64-bit Arm (aarch64) architectures available on OCI.
• Storage: Requirements vary based on OCI compute instance size. For monitoring OCI instances, the Oracle Management Agent recommends a minimum of 300 MiB of available disk space.
• Display: Not applicable for a cloud-based server operating system.
• Ports: Managed by Oracle Cloud Infrastructure networking configurations.
• Operating System: Oracle Autonomous Linux is the operating system itself, based on Oracle Linux.

Analysis of Technical Requirements

The technical requirements for Oracle Autonomous Linux are highly flexible, as it runs on Oracle Cloud Infrastructure. Users provision OCI compute instances with varying specifications, allowing for scalability from small development environments to large-scale enterprise workloads. The underlying Oracle Linux is optimized for performance on OCI hardware, including Intel, AMD, and Arm processors. The minimal requirements for agents suggest that the OS itself is efficient, but overall resource consumption depends on the applications and services running on it.

Support & Compatibility

Oracle Autonomous Linux offers robust support and broad compatibility, particularly within the Oracle ecosystem and with Red Hat Enterprise Linux (RHEL) applications.

• Latest Version: Oracle Autonomous Linux 9.x.
• OS Support: Runs on Oracle Cloud Infrastructure (OCI) on 64-bit Intel/AMD (x86_64) and 64-bit Arm (aarch64) architectures. It is fully application binary compatible with Red Hat Enterprise Linux (RHEL), allowing RHEL applications to run without modification.
• End of Support Date: Oracle Linux Premier Support is included with paid OCI subscriptions at no additional cost. Oracle Autonomous Linux 7.x is in extended support.
• Localization: General Oracle Linux support for various locales is implied, though specific localization features for Autonomous Linux are not detailed.
• Available Drivers: Utilizes drivers compatible with Oracle Linux and OCI. Critical updates for the kernel and key user space libraries are delivered via Ksplice technology.

Analysis of Overall Support & Compatibility Status

Oracle Autonomous Linux boasts a strong support and compatibility profile. Its foundation on Oracle Linux ensures a proven and reliable operating environment. The key strength lies in its full application binary compatibility with RHEL, which simplifies migration and deployment for enterprises already using RHEL-certified applications. Support is comprehensive, integrated directly into OCI subscriptions, providing access to Oracle's expert Linux support. The continuous, zero-downtime patching via Ksplice ensures systems remain up-to-date and compatible with the latest fixes without requiring reboots.

Security Status

Security is a core tenet of Oracle Autonomous Linux, featuring automated processes to minimize vulnerabilities and enhance system integrity.

• Security Features: Includes automatic daily security updates and patches, zero-downtime patching for the kernel and critical user space libraries (glibc, OpenSSL) using Ksplice technology, and known exploit detection with automated alerts. It also offers self-tuning and fault detection/resolution capabilities.
• Known Vulnerabilities: Actively mitigates known vulnerabilities through continuous, automated patching. Known exploit detection notifies administrators of attempted attacks against patched vulnerabilities.
• Blacklist Status: Not applicable for an operating system.
• Certifications: Oracle Linux platform images are regularly updated with security patches. For specific certifications like FIPS 140-3 or Common Criteria, Oracle recommends checking their Security Evaluations page, noting that FIPS mode is not enabled by default.
• Encryption Support: Ksplice technology updates OpenSSL, a widely used encryption library. Oracle Linux also supports Secure Encrypted Virtualization (SEV) for AMD-V enabled processors.
• Authentication Methods: Standard Linux authentication mechanisms are supported, with access control managed through Oracle Cloud Infrastructure Identity and Access Management (IAM) policies.
• General Recommendations: Oracle advises limiting user privileges, regularly applying security patches (though largely automated by Autonomous Linux), removing unnecessary packages, and reviewing security compliance reports.

Analysis on the Overall Security Rating

Oracle Autonomous Linux offers a high level of security, primarily driven by its autonomous capabilities. The daily, zero-downtime patching ensures that systems are consistently protected against the latest threats without operational disruption. Known exploit detection adds an extra layer of proactive defense by alerting administrators to attack attempts. Operating within OCI, it benefits from Oracle's shared security responsibility model, where Oracle secures the underlying infrastructure, and users are responsible for configuring their cloud resources securely. This combination significantly reduces the attack surface and human error, leading to a strong overall security posture.

Performance & Benchmarks

Oracle Autonomous Linux is engineered for high performance and efficiency within the Oracle Cloud Infrastructure.

• Benchmark Scores: Specific public benchmark scores for Oracle Autonomous Linux are not widely published. However, it leverages the Unbreakable Enterprise Kernel (UEK), which is highly optimized for performance and powers Oracle's high-performance systems like Exadata.
• Real-world Performance Metrics: Improves application performance through kernel optimizations and self-tuning capabilities that efficiently manage resources. It is designed for demanding enterprise applications and mission-critical workloads.
• Power Consumption: Not directly attributable to the operating system, but rather to the underlying Oracle Cloud Infrastructure compute resources.
• Carbon Footprint: Not directly attributable to the operating system, but rather to the underlying Oracle Cloud Infrastructure data centers.
• Comparison with Similar Assets: Positioned as a highly automated and cost-effective alternative to other enterprise Linux distributions like Red Hat Enterprise Linux (RHEL), offering significant operational cost savings due to reduced manual administration.

Analysis of the Overall Performance Status
