Overall Satisfaction with IBM Z

Our team create IaaS solution designs incorporating IBM Mainframe server, DS8000 storage technologies. The implemented IaaS solution used for host other commercial corporations Mainframe infrastructure. We also provide modernization service for aged deployments during the migration.
IBM Mainframes turned out are very reliable, secure and powerful computer systems. With proper pricing, their TCO can be really competitive compared with other systems.
On the downside, these are very archaic systems, very different mindset required for Mainframe operation than for any other more popular systems. Therefore very few people has proper knowledge, and finding / educating a workforce is challenging.

Would you buy IBM Z again?


IBM Z is well suited for existing Mainframe systems, where the migration cost to other architecture (money and time!) would be too high. And in that case if these systems require extending with additional functions for capacity. Meanwhile for green field deployments would makes much more sense to choose one of the other open systems, due to the much wider support personnel availability.
