Q

Hyper Protect Servers

A

allow for the creation and running of virtual servers on IBM LinuxONE(most secure Linux-based platform) and provide access to Z technology without purchasing any unique hardware or having unique Z skills. They offer added security as the servers are deployed in any secure service container. They are as easy to configure and deploy as any other virtual machine but can only be deployed to specific data centers in Dallas, Frankfurt, Sydney, and Washington.
