Can WordPress Scale?

Yes. But there are requirements:

A single WordPress can push hundreds of millions of pageviews a month; it can serve tens of thousands of concurrent logged-in users; and it can be lightning-fast the whole time. It is known. The question is not whether WordPress itself can scale, but whether or not your implementation is ready.

This site contains best practices from teams with real-world experience in delivering WordPress at scale. They provide a solid foundation for planning a scalable implementation, both for development teams and site owners alike.


We all stand on the shoulders of giants. Learn trusted architectural patterns for scalable website infrastructure, as well as the optimizations that nearly all big sites leverage.
