The three products I have in mind were are all conventional 'lxc/docker' containers. Two are provided with docker-compose scripts. Two are available as either containerized or traditional products. One is container only.
Normally docker-compose should be portable. If they have OCI images they should be runnable on MicroVMs (no lxc container) with fly.io, Google Cloud Run, https://katacontainers.io/ and others.
The point I'm trying to make is that if you're aware of different ways to run an OCI image, you can run things in virtually the same way as the old way of having things packaged as a VM image (AMIs on EC2).
It does prevent you from setting up your own OS distribution and integrating the app directly with it, but so do AMIs.
