I am hosting some WP sites on a digital ocean VPS. My current setup is the default config where all media files are uploaded to and served by my server. To take off the load, I’d like to use a CDN instead. Still shopping around, possibly Cloudflare or AWS S3. What is the go-to WP plugin for a seamless integration with 3rd party CDNs? And what are some gotchas I need to be careful of as I shift this responsibility from my server to a CDN? They’re all new websites with no traffic rn so some downtime is fine.
