Scaling

We also discussed how scaling is a viable option but with diminishing returns and increasing expenses. Both vertical and horizontal scaling have their own pros and cons. Vertical scaling is seemingly easier to begin with: investing in IT infrastructures, such as RAM upgrades and disk drives. However, the return plateaus out very quickly. The disadvantage of the downtime required for vertical scaling doesn't exist in horizontal scaling. However, beyond a point, the cost of horizontal returns becomes too high.
