The Oracle BYOL Licensing Guide
Oracle BYOL, bring your own licence, lets a customer apply existing on premises entitlements to cloud compute instead of buying licence included capacity. Done correctly it removes duplicate software cost; done carelessly it leaves the organisation paying support on premises and software in the cloud for the same workload. This guide explains how to make BYOL save money rather than quietly double the bill.
Executive summary
Bring your own licence, almost always abbreviated to BYOL, is Oracle's mechanism for letting customers reuse software they already own when they move workloads to the cloud. Instead of paying a per hour rate that bundles the software, the customer applies its existing perpetual entitlements to cloud compute and pays a lower infrastructure only rate. On paper this is the obvious choice for any organisation with surplus licences. In practice BYOL is governed by eligibility rules, conversion ratios, and support obligations that decide whether it delivers the saving or quietly doubles the cost.
The central risk is paying twice. A licence moved under BYOL still carries its on premises support stream, and a customer that mismanages the move can find itself paying support on the perpetual licence and a licence included rate in the cloud for the very same workload. The second risk is the conversion: Oracle's eligible authorised cloud environment rules and OCPU or vCPU ratios determine how many on premises processor licences a given cloud shape consumes, and a mishandled conversion either wastes entitlement or under licenses the workload and creates an audit exposure in the cloud.
This white paper treats BYOL as a licensing decision with real money at stake, not an administrative checkbox. It explains BYOL versus licence included, the cloud eligibility rules, the conversion mathematics, and the support and double payment traps, and sets out a buyer side framework for moving workloads to the cloud without paying for the same software twice. Read it alongside our cloud and OCI licensing service and the OCI licensing guide.
