Microsoft Volume Licensing, CAL & ESU

A CAL is a licence that allows one user or one device to access a licensed server. The server licence and the CAL are two separate costs: having the server licence but not enough CALs still means you are not licensed correctly. HiTechCloud counts against the actual state of your systems to arrive at the number you need.

User CALs are cheaper when each person uses several devices. Device CALs are cheaper when several people share one machine — shift workstations or point-of-sale terminals, for example. HiTechCloud calculates both ways against your real figures before recommending one.

ESU extends security updates for a version that is past official end of support. It is for the situation where a business needs more time to upgrade but still has to patch security holes; it is not a long-term answer. HiTechCloud usually prepares both options side by side: the ESU cost for the transition period, and the cost of upgrading outright.

Buying outright suits systems that run long-term and stay stable. Renting monthly suits a business that resells services and needs licences that flex with customer numbers — for that case, see the Microsoft SPLA.
