Vertical vs horizontal scaling limit
What is the fundamental limit that eventually forces teams from vertical scaling to horizontal scaling?
Options
- 1Because a vertically scaled machine cannot attach SSDs or NVMe storage, which caps its usable throughput regardless of CPU
- 2A single machine has a hard ceiling on CPU, memory, and I/O, and cost grows super-linearly past that point
- 3Because adding resources vertically forces the team to rewrite the application in a compiled language to exploit the hardware
- 4Because spreading load horizontally makes a system exempt from CAP, so consistency and availability hold together
