There are lots of tools for CD in a container world, like Kubernetes and ECS. But many (most?) companies aren't using containers.
Which tools and best practices are you using to manage your deployments in a non-container world, when you have dozens of long-lived servers behind a load balancer?

DC/OS [1] supports services (long-running tasks) and jobs (one-offs or scheduled) which don't necessarily have to be container images. See also [2] for a small write-up on this topic.
Kubernetes is such an overkill for most companies. Unless you're deploying to dozens of servers of non-homogenous projects/services, you probably don't need it.
