Prior to deploying the Cloud Pak for Business Automation operator, which two common prerequisites exist for all Cloud Pak for Business Automation capabilities (excluding Business Automation Insights)?

Prior to deploying any IBM Cloud Pak for Business Automation capabilities, the underlying platform and cluster must be prepared. A user registry, such as an LDAP directory, is a mandatory prerequisite for the platform's Identity and Access Management (IAM) service, which handles authentication for all capabilities. Similarly, all stateful components within the Cloud Pak require persistent storage. Therefore, having pre-configured storage classes that can provision Persistent Volumes is a fundamental cluster-level prerequisite. These two elements, LDAP and Persistent Volumes, are foundational requirements for the platform itself, and thus are common prerequisites for any and all capabilities that will be deployed on it.

B. Database: While most capabilities require databases, the specific database creation is tied to the capabilities selected for deployment, making it a capability-specific prerequisite rather than a universal platform prerequisite.
D. Network Policies: Network Policies are security configurations applied to control traffic flow. They are considered a best practice for production environments but are not a mandatory prerequisite for the initial deployment.
E. Routes: Routes are created by the operator during the deployment process to expose services externally. They are a result of the deployment, not a prerequisite for it.

1. IBM Cloud Pak for Business Automation 23.0.2 Documentation

"Preparing for an enterprise deployment"

Section: "Preparing your LDAP server". This section states

"Cloud Pak for Business Automation requires an LDAP server for user authentication... The Cloud Pak foundational services Identity and Access Management (IAM) service is used to connect to your LDAP." This confirms LDAP is a foundational platform requirement.

2. IBM Cloud Pak for Business Automation 23.0.2 Documentation

"Preparing for an enterprise deployment"

Section: "Preparing storage". This section details the necessity of persistent storage

stating

"You must have storage that is ready to be used for persistent volumes... Before you apply the custom resource

you must create the persistent volume claims (PVC) manually or you must have a storage provisioner that can create them dynamically." This establishes persistent storage as a core prerequisite.

3. IBM Cloud Pak for Business Automation 23.0.2 Documentation

"Preparing for an enterprise deployment"

Section: "Preparing databases". The documentation states

"For each capability that you want to include in your deployment

you must create the databases." The phrasing "For each capability" indicates that this is a conditional prerequisite based on the chosen components

unlike the universal requirements for LDAP and storage.
