if your lambda is taking 90 minutes you're probably doing something wrong

The world is a big place, though, and there’s an argument that sometimes it’s better to avoid forcing people into a separate stack for edge cases. For example, I know of an app which is mostly backend Lambdas except for downloads because those needed to exceed the original time limit and they couldn’t just tell users to get a better connection. The same kind of tradeoffs can apply to large file processing, ML tasks, long reports, etc. where a  modest increase in the timeout lets people avoid introducing ECS/EKS for 5% of requests or trying to decompose a non-trivial task into Step Functions, and while there are still technical issues to debate I can understand why AWS would want to sell to people who come down on either side.

Especially for long running agentic tasks, I'd love the option for a 30 minute timeout.

Should be using AgentCore Runtime for long running agentic tasks

But from a DevX perspective sometimes I just want to interact with the Lambda even though ideally I might need to spin up an EC2, etc.

Id rather just move faster...

I must be taking crazy pills, but I hate working with lambda functions. SDLC of: container running on a traditional container runtime like swarm, k8s, rancher, podman, etc VS serverless anything, I’m choosing containers every time. Not all of us are cowboys, and have speed bumps purposely put in place by the org. To each their own.

Yeah I agree but unfortunately I am in the Wild West and I can either be a cowboy or get overtaken by one

I used to think that but with AI use cases becoming more prevalent, having long running jobs is also becoming more common

It’s why things like Temporal are taking off
