Oracle licensing on Azure

Oracle’s powerful database solutions and Microsoft Azure’s versatile cloud infrastructure have become appealing to enterprises seeking scalability, flexibility, and integration. However, Oracle licensing on Azure can be complex, with distinct requirements, rules, and potential pitfalls.

This guide explores how Oracle licensing works on Azure, its benefits, key considerations, and strategies to avoid licensing issues, especially during Oracle audits.

Oracle Licensing on Azure: Overview

Oracle has recognized Microsoft Azure as an authorized public cloud environment for licensing Oracle software. This recognition means that enterprises can deploy Oracle software on Azure while benefiting from Oracle’s unique cloud licensing model.

Azure provides an alternative to Oracle Cloud Infrastructure (OCI), offering diverse tools and services for enterprises seeking flexibility in their cloud deployment strategy.

Key Licensing Characteristics:

• Azure is Authorized: Azure is officially recognized by Oracle as a public cloud environment for licensing.
• vCPU-Based Licensing: Licensing on Azure is primarily based on the number of virtual CPUs (vCPUs) used.
• Constrained vCPU Options: Azure provides a constrained vCPU model to optimize licensing, allowing companies to reduce license needs.
• No Core Factor Table: Unlike on-premises environments, Oracle’s Core Factor Table is unnecessary when licensing on Azure.

How Does Oracle Licensing on Azure Work?

Oracle Licensing on Azure relies on counting the number of virtual CPUs used in the cloud environment. Unlike traditional on-premises licensing, where the number of physical cores and the Core Factor Table determine license requirements, Azure’s licensing model simplifies the calculation process.

• Multi-Threading and vCPUs: Two vCPUs are counted as one processor license if multi-threading is enabled. This rule reduces licensing costs and ensures compliance with Oracle policies.
• Virtual Machine Instances: Organizations must calculate the number of vCPUs deployed for their Oracle software on Azure. Each set of two vCPUs (multi-threading enabled) equals one Oracle processor license.

Examples:

• For eight vCPUs, you would need 4 Oracle processor licenses if multi-threading is enabled.
• For 16 vCPUs, you would need 8 processor licenses.

If you are using Oracle Database Standard Edition 2:

• Two vCPUs require one processor license.
• Eight vCPUs require two processor licenses, but the Standard Edition 2 cannot be licensed on more than eight vCPU instances.

These calculations are essential to ensure compliance and avoid licensing pitfalls during audits.

Benefits of Licensing Oracle on Azure

Licensing Oracle on Azure provides several benefits, especially regarding flexibility and cost management. Here are some of the key advantages:

• vCPU-Based Licensing: Azure’s vCPU-based licensing allows you to license only the capacity you need, providing more granular control over licensing costs.
• Constrained vCPU for Optimization: Azure’s constrained vCPU model enables organizations to customize the number of active vCPUs, reducing the number of Oracle licenses required. This is particularly beneficial for database workloads that need high memory and storage but lower CPU usage.
• No Core Factor Requirement: Companies do not need to use the Core Factor Table when licensing Oracle on Azure, which often complicates on-premises licensing.
• Cloud Flexibility: Azure offers a flexible infrastructure, allowing organizations to scale their Oracle deployments based on demand without overcommitting on licenses.

Common Oracle Licensing Challenges on Azure

Deploying Oracle on Azure can present some licensing compliance and optimization challenges. Here are some of the common issues:

• Territory Clause Issues: Carefully review the territory clause in your Oracle Ordering Document to determine whether you can deploy Oracle software in the specific Azure region where you plan to operate. Some restrictions may apply depending on the agreement.
• Standard Edition 2 Restrictions: Oracle Database Standard Edition 2 has a strict limitation on Azure regarding the number of vCPUs. It cannot be deployed on instances with more than eight vCPUs, which may limit its scalability in certain scenarios.
• Oracle ULA Considerations: If you are under an Oracle Unlimited License Agreement (ULA), it’s important to understand whether Azure deployments count towards your exit metrics. In many cases, Oracle does not allow customers to count Azure deployments as part of their ULA exit certifications.

Constrained vCPU on Azure for License Optimization

Azure offers constrained vCPU options to optimize Oracle licensing costs. These virtual machine configurations allow you to limit the number of active vCPUs, effectively lowering the Oracle licensing burden.

Why Constrained vCPU is Important:

• Many Oracle workloads are not CPU-intensive but demand high memory, I/O, and storage performance. Constrained vCPUs allow companies to use fewer vCPUs, thus needing fewer licenses.
• Oracle’s cloud licensing policy states that customers must count the maximum available vCPUs, not the total number in an unconstrained VM. Using constrained vCPU models ensures compliance and reduces unnecessary licensing costs.

Example:

• Suppose you use a 16-vCPU VM but only require 8 vCPUs. Using a constrained configuration, you can halve the number of Oracle licenses needed from 8 to 4, leading to significant cost savings.

Oracle Audits and Licensing Compliance on Azure

Oracle audits are a major concern for organizations using their software, especially in cloud environments like Azure. Oracle may want to validate your compliance with their licensing policies, which can lead to financial penalties if non-compliance is discovered.

Tips to Avoid Audit Issues:

• Limit Information Sharing: If Oracle requests information about your deployment, do not disclose the specific instance type. Only provide the number of vCPUs used.
• Non-Contractual Policy: The Oracle cloud licensing policy is typically labeled as “non-contractual” in Oracle’s documentation. This means it does not form a binding agreement, and Oracle cannot enforce it as strictly as other contractual terms.
• Maximum Available vCPUs: Ensure that you only license the maximum available vCPUs as defined in the Azure environment. If constrained vCPUs are configured, your licenses should only reflect the reduced capacity.
