I gave a talk at WordCamp San Diego 2016 on the modern WordPress server stack. This is the companion article that I wrote for it. If you’re just looking for the slides, click here. It was also later republished on Smashing Magazine.
Do you remember when you could run a “fast” WordPress site with just an Apache server and PHP? Yeah, those were days! Things were a lot less complicated back then.
Now, everything has to load lightning fast! Visitors don’t have the same expectations about loading times as they used to. A slow site can have serious implications for you or your client.
As a consequence, the WordPress server stack has had to evolve over the years to keep up with this need for speed. As part of this evolution, it’s had to add a few gears to its engine. Some of the older gears have had to change as well.
The result is that today the WordPress server stack looks quite different from a few years ago. To better understand it, we’re going to explore this new stack in detail. You’ll see how the various pieces fit together to make your WordPress site fast.
