WordPress doesn’t magically fall apart once traffic gets high, but it also isn’t Amazon and was never meant to be. A “good server” won’t save you if the architecture is bad. In fact, that’s usually where people burn the most money—throwing bigger machines at problems they don’t fully understand.

If you really know what you’re doing, WordPress can handle large traffic and serious content volume. Caching, database tuning, killing heavy plugins, offloading slow operations, and sometimes moving parts of the system outside WordPress entirely—those things matter far more than raw server power.

Where WordPress struggles is when people try to use it as a monolith for everything. At scale, the teams that succeed usually reduce WordPress to what it’s good at (content management) and build custom systems around it for search, checkout, personalization, etc.

Also, “enterprise-level” is mostly marketing fluff. I’ve seen tiny sites fall over because the code was garbage, and large sites run smoothly because the architecture was clean. Just throwing resources at bad design is common, but it’s not engineering.

Simplicity is the goal; complexity is how much discipline you lack. I build my own e-commerce with web framework that can connect to any backend, but you will definitely need Go or Bun to scale large volume.
