Oracle Database@AWS (ODB@AWS)
- Docs: https://docs.aws.amazon.com/odb/
- Docs (llms.txt): https://docs.aws.amazon.com/odb/latest/userguide/llms.txt
- Data model: Relational (Oracle Database, full feature set including RAC)
- Query language: Oracle SQL, PL/SQL
- Compatibility: Full Oracle Database (Enterprise Edition, RAC, Data Guard, all options)
- Serverless: Yes (Oracle Autonomous Database on Serverless); dedicated Exadata infrastructure also available
- Serverless type: Operations — Autonomous Database Serverless (ADB-S) runs on shared Exadata managed entirely by Oracle; no Exadata infrastructure or VM cluster to provision, and compute/storage auto-scale on demand (you create only an ODB network). Dedicated deployments (ADB-D, ExaDB-D) are not serverless
- Scale to zero: Near zero (serverless)
- VPC required: Yes (runs in customer VPC on Oracle-managed Exadata in AWS data centers)
- Multi-region: Oracle Data Guard (active-passive DR)
- Free Tier: None
- Min cost: ~$140/month (Standard Edition serverless); dedicated infrastructure starts ~$10k/month (Exadata + Oracle licensing, enterprise pricing)
- Time to first query: Minutes (serverless) to hours/days (dedicated infrastructure provisioning)
- Key features: Full Oracle Database feature parity (RAC, Data Guard, RMAN, ASM, Multitenant), runs in AWS data centers with low-latency access to other AWS services, managed by Oracle, BYOL or License Included
- Limitations: Oracle licensing cost, Exadata-only (no small instances), complex setup, managed by Oracle (not AWS), limited to regions with ODB@AWS availability
- Best for: Enterprise Oracle workloads requiring Exadata and/or RAC capabilities, Oracle-to-cloud migrations where RDS for Oracle feature gaps are blockers, consolidation of Oracle estates onto cloud infrastructure
- Not for: New applications, teams looking to move off commercial licensing (that's a refactor to Aurora PostgreSQL)
