I don’t believe that the FaaS revolution has stalled, though I fear it will follow the tech adoption curve because people are over hyping it.
I do wonder if AWS’s leadership in the area has stalled though.
GCP has innovated with their hybrid Cloud Run to allow running more traditional apps in a serverless way.
Azure and CloudFlare have paved the way to what I believe is the future with stateful functions with Durable Functions and Durable Objects respectively.
Meanwhile Lambda just seems to be gold plating it’s (admittedly great) but stale offering.
