I mean, technically, you could containerize all the elements you need. Firewall, load balancers, identity management, etc. but at that point, you are creating your companies own version of the cloud services that are generally one of the big draws to the cloud already since you aren’t directly developing and maintaining those systems anymore. Once you have made “aws lite” in container form, you can then deploy that directly to the compute instances on any cloud provider. But now you need to maintain everything like you were running on prem (i.e. more developers and network engineers again) all while paying a pretty penny to multiple cloud providers and now that your infrastructure containers need to run 24/7 instead of only having your compute resources being ran on demand your costs will skyrocket so at that point why not just move back to on prem hosting.
