• Storage: Provisionable from 32 GB (fractional) up to 128 TB, with options for larger storage by contacting Oracle.
• Display: Not applicable to the database service itself; client applications require standard display capabilities.
• Ports: Client connections use TCPS (Secure TCP) with TLS 1.2 for secure communication.
• Operating System: Client applications and tools can run on various operating systems that support Oracle client software (OCI, JDBC, ODBC).

Analysis of Technical Requirements

The technical requirements for Oracle Autonomous Database are highly flexible and elastic, reflecting its cloud-native design. The ability to provision fractional OCPUs and granular storage in GBs (as low as 0.1 OCPU and 32 GB) allows for cost-effective deployment for smaller workloads and development environments. For larger, mission-critical applications, the service scales up to 128 OCPUs and 128 TB of storage, with auto-scaling providing burst capacity. This elasticity ensures resources align closely with actual workload demands, optimizing performance and cost. The reliance on standard secure network protocols (TLS 1.2) for client connectivity ensures broad compatibility with existing applications and tools.
