Book description

This IBM® Redbooks® publication introduces the latest member of the IBM Z® platform, the IBM z15™ (machine type 8561). It includes information about the Z environment and how it helps integrate data and transactions more securely. It also provides insight for faster and more accurate business decisions.

The z15 is a state-of-the-art data and transaction system that delivers advanced capabilities, which are vital to any digital transformation. The z15 is designed for enhanced modularity, which is in an industry-standard footprint.

The z15 system excels at the following tasks:


  • Using multicloud integration services
  • Securing data with pervasive encryption
  • Providing resilience with key to zero downtime
  • Transforming a transactional platform into a data powerhouse
  • Getting more out of the platform with IT Operational Analytics
  • Accelerating digital transformation with agile service delivery
  • Revolutionizing business processes
  • Blending open source and Z technologies

This book explains how this system uses new innovations and traditional Z strengths to satisfy growing demand for cloud, analytics, and open source technologies. With the z15 as the base, applications can run in a trusted, reliable, and secure environment that improves operations and lessens business risk.
