Of course every "edge" is just another data center, but there's a massive rise in functions/serverless computing platforms focused on moving compute to more PoPs globally. Some have now graduated to running full containers as well.

If you have a stateless app, or state that can be deployed in multiple locations, then these are good solutions compared to doing it yourself and are relatively easier to deal with than the IaaS options of the clouds. Having it built into the CDN layer only helps with performance.
