It's funny how the article mentions AWS lock-in but fails to recognize the infrastructure lock-in aspect of relying on a whole container/orchestration/virtualization stack that is so fragile that (according to the article) the only way to reasonably use it in production is to outsource its maintanenace.
Once you go down this path, it seems there is a very a limited number of providers capable of providing the infrastructure you require (at least compared to vps/dedicated/datacenter providers) and they can just keep pushing you into using more and more fragile infrastructure components that you would never want to maintain yourself.
Eventually, you may very well find yourself paying so much for all the hardware/virtualization/os/container/orchestration maintenance and resource overhead, with a number of backup instances of everything due to the unreliability of all these components, that you wish you could just go back to placing a few pieces of metal in a few datacenters and call it a day.
