Oracle vs AWS RDS, two licensing paths.

A side by side comparison of Oracle Database on premises versus Amazon RDS for Oracle on license, support, options and the workloads where each path wins.

Amazon RDS for Oracle offers two licensing paths: License Included and Bring Your Own License.

License Included rolls the Oracle Database fee into the AWS bill at a premium over on premises list pricing.

BYOL uses existing Oracle licenses under the Authorized Cloud Environment counting rules.

This comparison covers the model, the direct cost, the option restrictions and the workloads where each path wins.

How do the two models compare?

License Included

License Included pricing is set per RDS instance type and edition.

AWS pays the Oracle fee to Oracle and bills the customer at a margin.

• No customer Oracle contract required for the License Included instances.
• No Oracle support contract required, AWS handles support.
• Limited option support, with Partitioning, Diagnostics and Tuning excluded.
• No CSI registration needed for License Included instances.

Bring Your Own License

BYOL uses existing Oracle licenses, counted under the Authorized Cloud Environment rules.

Two vCPUs map to one Processor license on hyperthreaded RDS instance types.

What does the direct cost look like?

Small instance, db.m5.large

License Included Enterprise Edition on db.m5.large lists at around $0.80 per hour, or roughly $7,000 per year per instance.

BYOL on the same instance type requires one Processor license at $47,500 list plus $10,450 annual support, but no AWS license premium.

Medium instance, db.r5.4xlarge

• License Included at around $5.00 per hour, $43,800 per year per instance.
• BYOL requires eight Processor licenses at $380,000 list, $83,600 annual support.

Where the breakeven lands

BYOL pays back on instances that run continuously for two or more years.

License Included pays back on intermittent workloads, test environments and pilot phases.

RDS License Included pays the AWS premium for operational simplicity. BYOL preserves the Oracle entitlement and unlocks every option. Different paths for different workloads.

What about options and packs?

Options on RDS License Included

• Partitioning is not available on License Included.
• Diagnostics Pack is not available on License Included.
• Tuning Pack is not available on License Included.
• Advanced Compression is not available on License Included.
• Active Data Guard is not available on License Included.

Options on BYOL

All Oracle options work under BYOL if licensed and current on support.

Each option must be separately licensed and counted under the cloud rule.

When does each path win?

When RDS License Included wins

• Pilot phases and proof of concept work.
• Test and development environments with intermittent use.
• Workloads that fit Standard Edition 2 without advanced options.
• Teams without an existing Oracle support contract.

When BYOL wins

Production workloads that run continuously.

Workloads that require Partitioning, Diagnostics, Tuning or Advanced Compression.

Estates with an existing Oracle support contract already paid.

Workloads moving from on premises to AWS with existing entitlement to redeploy.

What to do next

1. Inventory candidate Oracle workloads by usage pattern and instance size.
2. Tag each workload as continuous, intermittent or pilot.
3. Score each workload on advanced option dependency.
4. Model License Included and BYOL cost over a three year horizon for each workload.
5. Identify workloads where the existing support contract makes BYOL the obvious path.
6. Negotiate the AWS commitment alongside the Oracle support renewal.
7. Document the BYOL footprint with topology evidence at the start.
8. Plan an annual review of the License Included versus BYOL mix.

Frequently asked questions

Can we mix License Included and BYOL on the same account?

Yes. Each instance is licensed independently. Many estates run a mix.

Do we still need an Oracle support contract on License Included?

No. AWS handles patching and support for License Included instances.

Can we add Partitioning to a License Included instance?

No. License Included excludes premium options. Move the workload to BYOL or to a different RDS engine if Partitioning is required.

Does RDS BYOL trigger an Oracle audit?

Not directly. The BYOL workload is subject to the same Oracle audit terms as any on premises workload.

Do we save support fees with License Included?

Not exactly. The support cost is folded into the AWS hourly rate. The total is often higher than 22 percent of list, but it removes the need for a separate Oracle contract.
