    As businesses digitally transform, they can impose significant demands on existing mainframe applications and data requiring the need to modernize to achieve business outcomes.

    To meet this need for modernization which includes greater agility, efficiency, and innovation, they are choosing a hybrid cloud strategy that brings together the best of IBM Z and Cloud.

    IBM Z integrated into a hybrid cloud based on Red Hat OpenShift provides resiliency and secure architecture that allows for application workload placement on the “best fit” infrastructure to maximize scale, performance, and efficiency. You can accelerate application modernization today by using architectural patterns that are building blocks and best practices to learn how to implement and deploy application modernization in an IBM Z environment integrated with public cloud.

    In the IBM Redpaper, Accelerate Mainframe Application Modernization with Hybrid Cloud, REDP-5705, we discussed strategies and architectural solutions that can accelerate your mainframe application modernization by leveraging hybrid cloud environments.

    This IBM Redpaper Redbooks® publication takes that IBM Redpaper on a deeper dive as it discusses and demonstrates implementation approaches to modernization when adopting a hybrid cloud with IBM Z. We discuss and demonstrate application centric, data integration/access centric, and event driven modernization patterns. Additionally, we provide a chapter on modernizing an enterprise’s DevOps with patterns and a chapter on managing your applications.

    Finally, we conclude with a demonstration of deployments of production applications.

    This IBM Redbooks publication provides information for IT Architects, IT Specialists and system administrators.
