System Requirements

Ready to install IBM Financial Services Workbench? Before you get started, use the information in this document to determine whether you have sufficient resources to install the service and the required software dependencies for the service.

Hardware Resources


Hardware	Number of Servers	Available VPCs	Memory
x86-64	3+ worker nodes. The nodes must be able to schedule pods	16 virtual processor cores (VPCs)	64 GB

A dynamic storage provisioner is required to be present on the cluster. The core product has only modest requirements in terms of PVC storage access modes - only ReadWriteOnce (RWO) is required. If you are installing other pre-requirements software onto the same cluster, i.e. MongoDB, kafka, Keycloak, additional access modes might be required.

Note: Use a storage provider with 500 GB or more of available space for your cluster. Tested providers include AWS EBS volumes, NFS, Portworx and OpenShift Container Storage. Squash must not be enabled on the NFS server, and all nodes in the cluster must have access to mount the NFS server and read/write access.

OpenShift Setup

Please make sure you are running the following versions:

To setup OpenShift please follow the instructions in the OpenShift documentation

Attention: For some preparatory steps a user with the cluster admin role is required. These steps are clearly marked. Once the product is installed this role is no longer required for the users working with IBM Financial Services Workbench.

Cloud Pak for Data

IBM Financial Services Workbench 2.9 runs as a service with IBM Cloud Pak for Data 3.5. Please make sure that the Cloud Pak for Data control plane is installed in the OpenShift cluster.

Detailed information on how to install IBM Cloud Pak for Data control plane you can find here .

Required Third-Party Components

Apache Kafka*	Version 1.0.2 or higher	Cores: 12, Memory 16 GB	20 GB
Keycloak	Version 5.0 or higher	Cores 1, Memory 2 GB	--
Git provider	See below	--	--

Besides the Open-Source version of Apache Kafka, commercial distributions such as RedHat AMQ Streams 1.5 or Cloud Offerings such as Confluent Cloud or IBM Event Streams are supported as well.

Attention: Keycloak is only supported with HTTPS mode enabled. It needs proper certificate and hostname setup.
