Oh man, he goes straight to stateful services as an alternative to JWTs. What an absolute nightmare, if JWTs are too hard stateful services are certainly more difficult.
Most websites don’t need it, and it makes things harder to manage when rolling out new versions of your services. Life got significantly easier once I moved away from stateful services.
Even at a new company I don’t think I’d ever want to go back to stateful sessions. I’m not close to Google or Amazon scale, and managing state was significantly harder than dealing with JWTs.
