Play with a free Platform.sh account, it’s what Adobe Commerce Cloud is based on and it’s practically identical with a few caveats. I went through the exercise of deploying the Magento Cloud GitHub project to Plathorn.sh a few years ago - I think you can likely do this without an enterprise license. You can at least get far enough to get some real experience
I see this differently, Adobe is trying to turn Magento into a headless commerce service. They want to position it so functionality is brought in through managed cloud services like through Adobe Exchange and API Mesh. I don’t think Adobe wants to maintain the same Magento codebase longterm, I think they’re actively building the enabling technologies to move on from it.
PHP’s actually going through a bit of a golden age. It’s a fine choice for web projects.
This is interesting, the built-in server has many advantages over FPM for development, but desperately lacking some tool to manage it. I will see if I can work this in to my workflow!
I feel like the most useful thing to know for anyone still using Magento 1 is that they should probably immediately upgrade the codebase to openmage https://github.com/OpenMage/magento-lts because jfc, and then seriously consider if their life would be improved with moving to some cloud service that manages security for them.
