Sold in standardized 2-core increments with a minimum 4-core licensing requirement per physical server, this core-based license enables unlimited simultaneous user, application and web traffic access without purchasing separate Client Access Licenses (CALs), supporting seamless linear scalability by adding extra 2-core packs as business data demands expand. It operates consistently across on-premises hardware, Windows/Linux virtual machines, Azure cloud IaaS and hybrid multi-cloud architectures, and unlocks exclusive enterprise capabilities unavailable in Standard edition, paired with full native AI, ultra-scalable performance, industry-leading high availability and end-to-end enterprise securityMicrosoft Learn.
Core Licensing Advantages of the 2-Core Pack
CAL-Free Unlimited Access Model
Each 2-core license covers two physical or virtual CPU cores, granting unrestricted connections for internal staff, public web visitors, SaaS tenants and automated API integrations. No extra CAL fees are required for end-user access, drastically simplifying license management for high-traffic e-commerce platforms, multi-tenant SaaS backends and customer-facing systems with unpredictable user volumes.
Modular Linear Scaling
Scale compute capacity precisely to match server hardware by stacking additional 2-core packs; there are no artificial caps on total licensed cores, enabling expansion from small virtual test environments up to large multi-socket production clusters. With active Software Assurance, the license includes license mobility across virtual hosts, passive failover replica rights and unlimited virtualization deployment privileges on licensed physical serversMicrosoft.
Flexible Cross-Environment Deployment Rights
Valid for physical on-prem servers, cloud virtual machines, Linux and Windows OS environments, supporting hybrid workflows that sync on-prem transaction data with Azure SQL Managed Instance, Microsoft Fabric and Azure OpenAI services for unified cloud analytics and AI workloads.
