- Licensing
The Enterprise-only features that matter
Both editions ship the same database engine, the same T-SQL, the same DMVs. The difference is scale ceilings and high-availability features.

| Max cores | 24 | Unlimited |
| Max buffer pool memory | 128 GB | OS max |
| Always On Availability Groups | Basic (2 replicas) | Up to 9 replicas |

Decision checklist
Run down this list. If you don't tick any item, Standard is the right pick.
- · Need >24 cores or >128 GB buffer pool? → Enterprise.
- · Need multi-replica Always On with active-active reads? → Enterprise.
- · Need online index rebuilds on a 24/7 OLTP system? → Enterprise.
- · Public-facing app with anonymous users and very large data volume? → Enterprise (and per-core licensing).
- · ERP back-end, 50 internal users, single server? → Standard + CAL.
Frequently asked questions
- Can I downgrade Enterprise to Standard later?
- Yes, by detaching/attaching databases. Features unique to Enterprise (e.g. partitioned columnstore indexes) may need to be removed first.
- What about Developer edition?
- Free, full Enterprise feature set, licensed for development and test only. Never run production on it.
