Microsoft SQL Server Licensing Simplified into 7 Rules

Though I would share 7 rules of SQL Licensing Simplified that was in an SQL training Blog I follow

1. If you query it, you have to license it.
2. “It” means the Windows environment – all of the processor cores that Windows sees. (Things get a little weirder under virtualization.)
3. Running a backup or a DBCC is considered querying.
4. If you license it, and you pay Software Assurance, you get exactly one free standby server of equivalent size. (Standby means you’re not querying it.)
5. Standard Edition costs about $2k USD per core, but caps out at 16 cores and 128GB RAM (for SQL 2014, or 64GB for 2012).
6. Enterprise Edition costs about $7k USD per core.
7. Software Assurance is an additional annual fee that gives you free upgrades as long as you keep paying for it.
