Know about SQL Server edition

Enterprise

The Enterprise edition of SQL Server is designed for large-scale environments, capable of managing databases up to 524 petabytes. It can address up to 12 terabytes of memory and supports up to 640 logical processors (CPU cores), making it ideal for mission-critical applications and high-demand workloads.

Standard

The Standard edition differs from the Enterprise edition in several key areas. It supports fewer active instances (the number of nodes in a cluster) and lacks some of the advanced high-availability features, such as hot-add memory. This edition is limited to a maximum of 4 sockets or 24 cores with 128 GB of memory, making it suitable for small to medium-sized businesses or less demanding workloads compared to the Enterprise edition.

Web

The SQL Server Web edition is a cost-effective solution designed for web hosting environments. It offers a low total-cost-of-ownership option with support for a maximum of 4 sockets or 16 cores and 64 GB of memory. This edition is ideal for small to medium-sized web applications with lower resource demands.

Express

SQL Server Express is a free, lightweight edition of SQL Server, ideal for lightweight applications, smaller databases, or learning purposes. It is limited to 1 socket or 4 cores with 1410 MB of memory, making it suitable for smaller applications or development environments that don’t require advanced features or extensive scalability.

Developer

SQL Server Developer edition provides developers with all the features of the Enterprise edition but is licensed for use solely as a development and test system. It allows developers to build and test applications on top of SQL Server, making it an excellent choice for those creating applications for production environments. This edition includes all the Enterprise features, but it is not licensed for production use.
