I work with a client that has us ssh in. We are committing on branches, and they are linked to testing subdomains. So there is some safety. In theory you can spin up a local copy. Almost no one does it. Between the micro services, needing to copy multiple SQL schemas, and seed it with test data, there are a lot of hurdles with little reward.

For my personal sites, one is just a scp, into a subdir. If everything looks good, I just mv it to overwrite live. The other I just restart the process. There's nothing "mission critical" on it.
