It's Funny How We Forgot About Container Sprawl
DevOps.com, Wednesday, November 15,2023
We are (thankfully) past the days when everything was a container. At least, most of us are. Just like anything else, some orgs will continue that approach for reasons both great and terrible. And all of us still use far more containers than we need, I would say
'One container, one function,' works if you are talking about one whole application, and maybe sometimes for busy parts of an application, but it certainly isn't needed to host a couple of low-use APIs, for example. My favorite example is separate instances of the same exact application for different teams (not business units - that is a good method to separate business units).
Thankfully, technology is once again saving us from ourselves and our misdeeds. Processing power is no longer an issue, meaning we can spin up a million containers and keep them running until our public cloud bill arrives.
