Security and Disaster Recovery

Linux on z Systems inherits world-class security features

The open-source nature of the Linux operating system already provides a favorable security profile, but running Linux on z Systems provides advantages which leverage the server-based security features.

Running Linux in an integrated environment with the z/VM virtualization technology and the z/OS or z/VSE operating systems on the same z Systems server offers additional security and administrative functions that can make Linux os more secure and easier to administer.

A full range of security features and applications are available from IBM, open source and software vendors to support a complete and cost-effective security infrastructure for the enterprise grade Linux on z environment.

Linux on z can benefit from high availability and disaster recovery solutions

The IBM Geographically Dispersed Parallel Sysplex (GDPS) solution is designed to avoid downtime by providing methods for managing servers, workloads, data replication activities and to plan reconfigurations efficiently.

When running a multitiered architecture, for example with application servers on Linux on z and database servers on z/OS, GDPS provides a function called “Multiplatform Resiliency for z Systems” (also known as xDR) to provide a coordinated near-continuous availability and disaster recovery solution for both z/OS and Linux.

Details are provided in the Redbook: GDPS Family: An Introduction to Concepts and Capabilities

New The IBM GDPS Virtual Appliance extends GDPS capabilities into z/VM and Linux on z environments that do not have z/OS in production. The GDPS Virtual Appliance is designed to provide a simple and easy-to-use GDPS platform through the use of a new and intuitive web interface for managing and controlling the environment.
