Horizontal Scaling : Horizontal scaling increases concurrency by scaling horizontally. As your customer base grows, you can use auto-scaling to increase the number of virtual warehouses, enabling you to respond instantly to additional queries.
Vertical Scaling : Vertical scaling involves increasing the processing power (e.g. CPU, RAM) of an existing machine. It generally involves scaling that can reduce processing time. Consider choosing a larger virtual warehouse-size if you want to optimize your workload and make it run faster.
