This is too funny. You may recognize "serverless" by it's common name "The Cloud". Read the wiki for "cloud computing" and you will quickly realize that is a z/OS complex. It must have been an IBM'r who wrote the specifications. After a few years, the specifications had to be relaxed because Unix was never going to meet the specs. Only z/OS could meet them. Cloud implementations SaaS, PaaS, FaaS and other "as a Service" implementations. Programs must complete these structures and transmit them. Alternatives are Peoplesoft, SAP and other standalone type of products. These cloud implementations are a lot of work to maintain. z/OS offers an exceptional cloud environment. Easy provisioning(SMS & RMF), easy security(RACF & sysplex complex), networking(SYSPLEX, TCP & SNA), scalability and elasticity (DFHSM, moveable dasd, moveable CPU, CICS, JES, IMS and much more). IBM made a huge mistake by not z/OS as the cloud without the all the work. Unix is loosely coupled so setting up, managing, maintaining and diagnosing problems are a huge challenge. There are many disparate technologies that must be configured to work together. It boggles the mind why any company would not choose z/OS because of it's cloud ready. > Dave wrote: So in terms of new systems the world has moved on.

Unix is a world of disparate free technologies that are not harmonious. 10 steps forward because Unix is open and you can do anything. 20 steps back because it's open and a lot of work. Just compare programmers responsibilities and you will see MVS programmers know their area of expertise where as Unix programmers are computer specialists. Jon.
