Of course -- you're still writing code to delete a key in Elasticache within your lambda. You're writing yaml code for deployments. Hence the "in the future" portion of this slide.

The scale-to-X and scale-to-zero features of Lambda, along with the guaranteed interface to your lambda with predictable input and output requirements, is incredibly empowering for an engineering team. I can absolutely guarantee that we have spent far, far, far less time maintaining our infrastructure than what we would need to be doing if we had a big-buncha-EC2 setup.

Imagine that the environment issues get taken care of, because Amazon has teams and teams and teams of engineers who are working on just that. Cloudflare has the zero-cold-start isolates. All these platforms are heavily invested in making your development and deployment experience as easy as it can be. Concentrate on writing your code, and you'll reap the benefits.
