Platform differences
Cloud Pak for Data as a Service and Cloud Pak for Data software share a common code base, however, they differ in the following key ways:
| Features | As a service | Software |
|---|---|---|
| Software, hardware, and installation | Cloud Pak for Data as a Service is fully managed by IBM on IBM Cloud. Software updates are automatic. Scaling of compute resources and storage is automatic. You sign up at Try Cloud Pak for Data as a Service. | You provide and maintain hardware. You install, maintain, and upgrade the software. See Software requirements. |
| Storage | You provision a IBM Cloud Object Storage service instance to provide storage. See IBM Cloud Object Storage. | You provide persistent storage on a Red Hat OpenShift cluster. See Storage requirements. |
| Compute resources for running workloads | Users choose the appropriate runtime for their jobs. Compute usage is billed based on the rate for the runtime environment and the duration of the job. See Monitor account resource usage. | You set up the number of Red Hat OpenShift nodes with the appropriate number of vCPUs. See Hardware requirements and Monitoring the platform. |
| Cost | You buy each service that you need at the appropriate plan level. Many services bill for compute resource consumption. See each service page in the IBM Cloud catalog or in the services catalog on Cloud Pak for Data as a Service, by selecting Services > Services catalog from the navigation menu. | You buy a software license based on the services that you need. For example, the Cloud Pak for Data Enterprise Edition license includes entitlement to services such as watsonx.ai Studio and IBM Knowledge Catalog. See Licenses and entitlements. |
| Security, compliance, and isolation | The data security, network security, security standards compliance, and isolation of Cloud Pak for Data as a Service are managed by IBM Cloud. You can set up extra security and encryption options. See Security of Cloud Pak for Data as a Service. | Red Hat OpenShift Container Platform provides basic security features. Cloud Pak for Data is assessed for various Privacy and Compliance regulations and provides features that you can use in preparation for various privacy and compliance assessments. You are responsible for additional security features, encryption, and network isolation. See Security considerations. |
| Available services | Most data fabric services are available in both deployment environments. See Services for Cloud Pak for Data as a Service. |
Includes many other services. See Services. |
| User management | You add users and user groups and manage their account roles and permissions with IBM Cloud Identity and Access Management. See Add users to the account. You can also set up SAML federation on IBM Cloud. See IBM Cloud docs: How IBM Cloud IAM works. |
You can add users and create user groups from the Administration menu. You can use the Identity and Access Management Service or use your existing SAML SSO or LDAP provider for identity and password management. You can create dynamic, attribute-based user groups. See User management. |
