A customer needs to easily adopt cloud-native design and development practices for new applications and their existing applications without cloud…

IBM Cloud Pak for Applications is the solution specifically designed to help organizations modernize existing applications and build new cloud-native applications. It provides an integrated set of tools and runtimes, including Red Hat OpenShift, which enables a consistent development and deployment experience across any public, private, or hybrid cloud. This container-based platform directly addresses the customer's need to adopt cloud-native practices for both new and existing applications while avoiding dependency on a single cloud provider, thus preventing lock-in.

A. IBM Cloud Pak for Data: This solution is an integrated data and AI platform. Its primary purpose is to collect, organize, and analyze data, not general-purpose application development and modernization.

C. IBM Cloud Pak for Security: This solution is focused on providing security insights and threat management. It connects disparate security tools and data sources, but it is not a platform for application development.

D. IBM Cloud Pak for Automation: This solution is designed to automate business processes and workflows. While it has development components, they are specific to automation tasks, not general cloud-native application development.

1. IBM Cloud Pak for Applications Documentation: "IBM Cloud Pak for Applications is an enterprise-ready, containerized software solution for modernizing existing applications and developing new cloud-native apps that run on Red Hat OpenShift."

3. Contrasting IBM Cloud Paks: Official documentation differentiates the Paks by function. IBM Cloud Pak for Data is for "AI Ladder," Cloud Pak for Automation is for "business automation," and Cloud Pak for Security is for "security operations." This clarifies that only Cloud Pak for Applications is centered on general application modernization and development.
