Should I license SQL Server per CAL or per core?
Short answer
Per-CAL (Server+CAL) is cheaper when you have fewer than ~25 named users hitting the database — typically internal LOB apps. Per-core is required for any internet-facing app, for SQL Enterprise above 24 cores, and is usually cheaper above 25 users.
The longer explanation
يرخّص نموذج Server+CAL خادم SQL واحد إضافة إلى CAL لكل مستخدم أو جهاز يقرأ أو يكتب أو ينفّذ استعلامات — سواء بشكل مباشر أو عبر برامج وسيطة. يناسب تطبيقات الأعمال الداخلية ذات العدد المعروف من المستخدمين ودون حركة مرور مجهولة من الإنترنت.
أما ترخيص Per-core فيغطي كل نواة فعلية (أربع نوى كحد أدنى لكل مقبس) ويسمح بعدد غير محدود من المستخدمين. وهو إلزامي لأي عبء عمل موجّه للإنترنت، والنموذج الوحيد المتاح لـ SQL Enterprise فوق 24 نواة، وغالبًا ما يكون أرخص عند تجاوز 25–30 مستخدمًا. في بيئات الافتراضية، يفتح Per-core مع Software Assurance عددًا غير محدود من الأجهزة الافتراضية لكل مضيف.
