Windows Server and SQL Server licensing guide

A planning guide to physical hosts, virtual machines, cores, CALs, SQL licensing models, high availability, disaster recovery, Azure, and buying validation.

Temen point of view

Server licensing starts with the deployment topology and access model. Record what runs where, then apply product rules and validate agreement-sensitive rights before choosing packs, subscriptions, or benefits.

Model the topology first

Separate physical hosts, processors, physical cores, virtual machines, operating systems, SQL instances, active and passive roles, and Azure workloads. SQL runs inside an operating system or VM; it is not automatically another server.

Physical host and installed cores
VM count and placement
Windows edition
SQL edition and role

Model access independently

Windows Server CALs, RDS CALs, and SQL Server plus CAL each answer different access questions. Administrative remote access is not automatically the same as an RDS session-host deployment.

Named users or devices
External access
RDS session hosts
Countable or public SQL access

Validate the commercial path

Azure license-included pricing, Azure Hybrid Benefit, per-VM options, mobility, passive recovery, downgrade rights, editions, and legacy agreements can depend on active coverage and current Product Terms.

Purchase program and geography
Active subscriptions or Software Assurance
Existing entitlements
Exact SKU, term, and fulfillment
