You should have development or pre-prod versions of your AWS services, for those areas local dev environments should point to those endpoints. Ideally each dev would have their own AWS sandbox, but I get it that sometimes that is an impractical solution so what I would personally do, is create a nightly (or unstable) instance where one can test their code against the latest code base and push needed changes to, a stable instance where known stable features and bug fixes get deployed and then a release instance where testers can test against items deemed fit to go out in the next release. Developers should switch their local to unstable and stable endpoints based on their needs as well as the condition of unstable. If someone breaks unstable, other developers can still progress against stable they just cannot push to it. So think of stable as can read but cannot write. Once unstable is back up, they can push any service changes they need to up to AWS. As a side note, it is the responsibility of whoever broke unstable to get it back up and running for the other devs.
