Not everyone buys into the cattle not pets thing. It's mainly a thing related to auto deployment strategies. Which are great for the cloud with its quick auto scaling capabilities. The ideal vision there is that you shouldn't even have the ability to log in to a server. But there are other usecases where a known environment you can poke around in is more useful IMO.

As an example, in cloud environments not much time is spent investigating issues. When something fails the solution is often to just wipe and redeploy. I prefer fully understanding the problem and having the tools to troubleshoot. Especially because in my work the servers still have different roles.
