SQL Server vs PostgreSQL: Which Scales Better?

What are the main differences in scaling between SQL Server and PostgreSQL?

SQL Server typically scales vertically, meaning it requires more powerful hardware. PostgreSQL, on the other hand, can scale both vertically and horizontally, allowing for more flexibility in distributed systems.

Can you explain what vertical and horizontal scaling mean?

Vertical scaling involves adding more resources (CPU, RAM) to a single server, while horizontal scaling means adding more servers to distribute the load.

Which one is more cost-effective for large applications?

PostgreSQL is often considered more cost-effective for large applications due to its ability to scale horizontally, which can reduce hardware costs.

Are there any specific use cases where one is preferred over the other?

Yes, SQL Server is often preferred in enterprise environments with existing Microsoft infrastructure, while PostgreSQL is favored for open-source projects and applications requiring complex queries.
