> Developers and Admins have more or less the same goals (stable, maintainable and extensible), but on different pieces of the system (code vs infrastructure).
I disagree because this generalizes both developers and admins too much for my own comfort. I've seen sysadmins get really sloppy in the name of getting something into production quickly out of hubris without thinking about the full lifecycle of an application (common with developer-turned-sysadmin engineers - I am one and tend to be more reckless due to the reality that most of the errors I've observed would not have been caught going super slow - that adding more test code does not necessarily find the most critical of errors, just increases confidence) and especially in enterprise software most developers are sitting on features and are nearly allergic to new trends by their organizations valuing revenue loss far above losing growth opportunities.
Of course the stereotype is that operations wants things stable and manageable at the behest of business while developers want to deploy new stuff faster (because the idea of development in most places is to create something new). Modern infrastructure becomes increasingly code-driven and emergent as opposed to manually formed and restrictively managed sysadmins will have more room for errors that may change this into the future. Meanwhile, developers are increasingly under greater scrutiny by society when rolling out features such that nobody can ignore the concerns and they may be eventually forced into nearly waterfall-like development patterns. We can already observe this with the infection of Agile with enterprise bureaucracy / overmanagement back into the rest of the software industry as many of the former smaller, agile tech companies become big behemoths themselves.
