Prerequisites

Version support

The current service version is IBM® Data Gate on Cloud Version 1.0.0.

The current service version is compatible with:

• Red Hat® OpenShift® 4.12.12
• Db2® (5737-L73)

Hardware requirements

The following requirements exist for a single instance of the product, that is, the Data Gate on Cloud server pod. More resources are needed for the entire cluster. For information on the cluster requirements, see Table 1.

Supported architectures

Determined by Amazon Web Services.

Min. number of virtual CPUs required for installation

2

Min. amount of memory (in GB of RAM) required for the service to run

13

Min. amount of storage (in GB) required by the service

50

Supported storage types

Data Gate on Cloud runs on Amazon Elastic Block Storage (EBS).

Software dependencies

Supported Red Hat OpenShift platforms

The only supported OpenShift platform is Red Hat OpenShift on AWS.

External dependencies

• IBM z/OS® Version 2.2 (5650-ZOS) or higher.

  For the z/OS Communications Server component of z/OS, install the following program temporary fixes (PTFs):

  • APAR PH30154
  • APAR PH32620
  • APAR PH38136
• One of the following database management systems:
  • IBM Db2 13 for z/OS
  • IBM Db2 12 for z/OS (5650-DB2® or 5770-AF3).

  For the required Function Level and the list of required PTFs, see Installing Db2 for z/OS maintenance to enable Data Gate on Cloud.

• Distributed data facility (DDF) with a secure port, configured for network encryption through AT-TLS. See Configuring network access between Data Gate on Cloud and IBM Z for configuration information.

Service dependencies

To run Data Gate on Cloud, you must provision Db2 Warehouse on Cloud on AWS as an additional service.

Note: See Provisioning a Db2 Warehouse on Cloud instance for more information.

Multitenancy support

Multiple instances of the Data Gate on Cloud service can be installed within a single Red Hat OpenShift cluster.

Required skill level

To deploy Data Gate on Cloud successfully, you need to be familiar with the Red Hat OpenShift command-line interface, and, to a lesser degree, with AWS services.

AWS requirements

See Table 1.

Key pair

Your AWS account needs to have one Amazon EC2 key pair in the region where you deploy the templates. Make a note of the key pair name. You’ll be prompted for this information during the deployment. To create a key pair, follow the instructions in Amazon EC2 key pairs and Linux® instances.

For testing or a proof-of-concept, create a new key pair. Do not reuse a key pair that’s already being used by a production instance.

AWS regions

The CloudFormation templates make the product available in 3 availability zones within a single region, but these must be regions in which Db2 Warehouse on Cloud can be deployed as well. Currently, only the following regions are supported:

• Nothern Virginia (us-east-1)
• Frankfurt (eu-central-1)

For a list of all regions, see AWS CloudFormation endpoints and quotas.

ROSA subscription

A deployment of Data Gate on Cloud requires that you install and run a Red Hat OpenShift cluster. The underlying product that provides this cluster is Red Hat OpenShift on AWS (ROSA). ROSA is available as an AWS service. To install and run the service, you need to obtain a service token. To obtain the token:

1. If necessary, create a Red Hat OpenShift account.
2. Enable ROSA.
3. Get the token.

IAM permissions

To use the template, you must log in to the AWS Management Console. The template requires sufficient Identity and Access Management (IAM) permissions for the resources it creates and the actions that it triggers. The AdministratorAccess managed policy within IAM provides sufficient permissions, although your organization may choose to use a more restrictive custom policy.

However, mind that AdministratorAccess is required for the creation of the ROSA cluster.
