Imagine If You Will….
Authorized Access at Lower Costs
- Bare System Z hardware OR through emulator systems
- Shared systems OR individually controlled
- Those for only one organization members OR which are open to many organizations
- Simple system access might be granted through UNIX Systems Services (USS), a UNIX interface z/OS. This approach contains users inside z/OS, requiring few security settings, and has a lower learning curve for many new developers coming from Linux systems.
- Medium system access would grant typical TSO (Time Sharing Option) access, which requires greater system administration and more use of required commercial software which would need to be controlled by the owners. This also requires greater operating system knowledge by users to use it effectively.
- Medium Plus access would grant greater application software access, such as databases and application development tools, increasing the system access requirements and knowledge of the users.
- Complex systems would be needed for System Z Sysplex control, an extremely scalable model using multiple System Z systems as one configurable unit.
