This is in an enterprise sized organisation with 10.000 employees.
We still have a sys ops team to handle security, network and all those other things, but deploying software? That’s really easy for our developers.
We use Azure DevOps, we deploy to Azure apps with a dev, testing, staging (5% traffic) and prod (95% traffic) slots. It takes maybe 5 minutes to go through the to-do-list when a new application or function or whatever is created and we have a very fascist naming convention. This isn’t an azure commercial, we’re only in azure because we’re the public sector and already so in bed with Microsoft that it’s the cheapest solution. I’m sure you could do the same in any other cloud.
