So prevents concurrent modification like that

@stocky-spoon-28903 thanks. So just one person can modify the whole environment ? That is fair enough ... So why the

Remote state

is being introduced in one of recent PRs ?

it doesn’t: it locks entire stacks

remote state with s3, at least, doesnt lock (yet), there are other discussions about adding locking. (if I recall). using pulumi's saas for your backend you do get locking by default. I dont know about the state of other backends for locking.

That is true: my answer is scoped only to using the pulumi service either in hosted SAAS or a private version

thanks @stocky-spoon-28903
