Vertical vs. Horizontal Scaling

Compare and contrast methods of scaling up (vertical) and scaling out (horizontal) to handle increased load.

What is System Scaling?

Ever wondered how popular apps handle millions of users without crashing? That's where system scaling comes in!

Scaling is about making your system capable of handling more work, like more users or data, without slowing down or failing.

Imagine your favorite online store on Black Friday. If it wasn't scaled, it would crash!

User Growth: More users mean more requests to process.
Data Volume: More users generate more data to store and retrieve.
Performance: Keep things fast and responsive for a good user experience.
Availability: Ensure the system is always accessible, even during peak times.
