Horizontal vs Vertical Scaling
· 2 min read
Horizontal scaling and vertical scaling are two strategies for increasing the capacity and performance of your application or infrastructure:
Horizontal Scaling (Scaling Out)
- Definition: Adding more machines or instances to your system.
- How: You deploy additional servers (e.g., more VMs, containers, or physical machines) to distribute the load.
- Benefits:
- Increases fault tolerance and availability.
- Easier to scale dynamically (especially in cloud environments).
- No single point of failure.
- Example: Adding more web servers behind a load balancer.
