Right, but zCX is not free.
Actually it’s no additional charge for 90 days. However, “it’s not free” is not
a meaningful argument. It’s *never* free to run applications in an enterprise
context at least. What matters is whether there’s sufficient or better
value-for-money compared to next best alternatives. “Money” here also includes
labor inputs and the many other cost-related ingredients.
Right. And for Linux deployments there are also public cloud operators
claim to reduce the cost of labor.
You have to pay a hardware license fee...
No, you don’t. On IBM z14 and IBM z15 machines you have the *option* to order
Feature Code 0104, and then there’s no additional software charge for/with
z/OS. Or you can choose the IBM Container Hosting Foundation for z/OS
(5655-HZ1), a monthly charge software element. On IBM z16 machines there’s no
Feature Code 0104, so you would choose the IBM Container Hosting Foundation for
z/OS. For this 5655-HZ1 software element there’s a further choice of flat or
tiered pricing. And you can change your mind. For example, you can start on
tiered then switch to flat or vice versa. Obviously you should compare (and
perhaps periodically re-compare) flat and tiered then pick the lower price.
Thanks, that's great info. "Feature Code 0104" sounds like the order
given to wipe out the Jedi :)
If you already deliver container images that support your product that
currently run outside z/OS, or if that’s what you plan to do, it’d be a great
idea to add s390x compatibility to your container images so your customers have
greater deployment flexibility. That’s usually quite easy to do.
Good advice. I would also add that if you are a vendor planning to
deliver zCX container images then make sure you add other
compatibilities just in case your customers don't run zCX. It could be a
POC obstacle.
Please note that Feature Codes 0103 and 0104 are NOT carry forward feature
codes. Obviously they don’t carry forward to IBM z16 (since they don’t exist on
that model), but they also did not/do not carry forward from IBM z14 to z15.
...plus assign zIIP, disk and storage resources.
You’re not strictly required to have or use zIIPs, but IBM recommends at least
one for zCX.
IMO, without zIIPs it's not viable.
As a periodic reminder, my views are my own. Always rely first on official IBM
publications and statements if you want to know what’s official.
