Horizontal Scaling Vs Vertical Scaling in System Design | Introduction to Scaling | #shorts

Welcome to Scaler's 1 Minute Explainer series! In this video, we'll discuss the difference between horizontal and vertical scaling in system design.

What is horizontal scaling?
Horizontal scaling, also known as "scaling out," is a system design approach where you increase the capacity of your system by adding more machines or nodes to your infrastructure. In this method, tasks are distributed across multiple servers or resources, allowing the system to handle increased loads by sharing the workload horizontally.

What is vertical scaling?
Vertical scaling, also known as "scaling up," is a system design approach where you increase the capacity of a single server or resource by adding more resources (e.g., CPU, RAM) to that server. In this method, the existing hardware is enhanced to handle increased workloads. Vertical scaling can improve a system's performance, but it has limits compared to horizontal scaling, which adds more servers to distribute the workload.

What is system design?
System design is the process of creating a detailed blueprint for a complex software or hardware system. It involves defining the system's architecture, components, data structures, and communication methods to meet specific requirements. The goal is to ensure that the system functions efficiently, reliably, and in accordance with user needs and business objectives.
