bert hubert 🇺🇦🇪🇺🇺🇦Stole this idea from @daedalus - the cloud is the new mainframe. Since then we had a few decades of hardware and software portability. And we are now back at "pick a cloud vendor and lock yourself in".

Including 'serverless' (like IMS), Horizontal scaling, availability, centralized access control (like RACF), virtualization (like LPARs), containers (like Address spaces), Encrypt everything (IBM's pervasive encryption).
And vendor lock-in because no one else deliver it anymore.
Cloud is not new..... :)
