Preparing to install Maximo Application Suite on Amazon Web Services

Before you install IBM® Maximo® Application Suite, consider your installation preferences, such as the type of Maximo Application Suite offering that you prefer and whether you want to reuse existing Maximo Application Suite compatible components in your new Maximo Application Suite instance.

You must also configure several prerequisite components before you install the Maximo Application Suite. For more information, see Installation requirements.

When you install the Maximo Application Suite, you must specify options for the following items:

Note: Starting in 8.11, for US GovCloud regions, you can install Maximo Application Suite in private hosted zones for existing Red Hat® OpenShift® cluster and New Red Hat OpenShift cluster by using the User Provisioned Infrastructure (UPI).

If this installation is your first Maximo Application Suite installation on Amazon Web Services, a new Red Hat OpenShift cluster must be created. If you already installed an instance of the Maximo Application Suite on Amazon Web Services, you can reuse the existing cluster.

If you want the installation process to create a new cluster, you must configure and consider the following items:
When you reuse an existing Red Hat OpenShift cluster, a prerequisites check is run in the cluster for following components:
  • Cloud Pak for Data, if you selected the Maximo Application Suite core and Cloud Pak for Data offering type.
  • SLS, if you do not specify an existing SLS instance to reuse.
  • Data Reporter Operator , if you do not specify an existing User Data Services instance to reuse.
  • MongoDB
  • Cert-manager

The components are reused if they are installed in the cluster with supported version. Else, new instances of the components are created in the cluster.

The deployment is stopped if an unsupported version is preinstalled for any of the components or if multiple instances of a component are running in existing cluster.

The prerequisites check also verifies whether the following storage classes are available in the cluster:

  • gp2
  • ocs-storagecluster-cephfs, if you selected Maximo Application Suite core and Cloud Pak for Data.

The following components are required to ensure that the cluster has enough resources to accommodate the new Maximo Application Suite instance.

  • Minimum number of worker nodes: 3
  • Minimum CPUs per node: 8 cores
  • Minimum memory per node: 32 GB

EBSVolumeType - Starting in Maximo Application Suite 8.11, select your preferred EBS Volume type which could be either gp3 or io1 for worker nodes based on your performance requirements and cost of the volume types.
