Topologies
Use IBM® WebSphere® Application Server to install a WebSphere Application Server traditional environment on a Red Hat® Enterprise Linux® 9.4 virtual server instance (VSI) on IBM Cloud®.
This documentation refers to WebSphere Application Server as WebSphere or WAS.
IBM® WebSphere® Application Server offers two topologies: WAS.Base
and WAS.Cell
. Specify one of these topologies as a value for the deploy_was_topology
parameter.
- WAS.Base
- The
WAS.Base
topology provisions one VSI with the latest release of WebSphere Application Server traditional V9.0.5.WAS.Base
provides a single server. This VSI has a public (floating) IP address. - WAS.Cell
- The
WAS.Cell
topology provides multiple VSIs with the latest release of WebSphere Application Server Network Deployment traditional V9.0.5.WAS.Cell
provisions one VSI with the deployment manager (DMgr), with one or more VSIs for custom nodes. You can also set up an IBM HTTP Server (IHS) VSI. DMgr and IHS VSIs have public (floating) IP addresses, while custom node VSIs have private IP addresses.
The installation sets up a new virtual private cloud (VPC), one or more VSIs, and relevant networking.
VPC details
The VPC, VSI, and related networking artifacts are created in the same resource group where the Schematics workspace is created. After the installation is complete, refer to the Resources section of the Schematics workspace for these artifacts. For more details about the artifacts, see information about virtual private clouds.
VSI details
-
All the VSIs are set up within the same subnet.
-
The VSIs for Base, DMgr, and IHS have public (floating) IP addresses and private IP addresses. For
WAS.Cell
, the custom nodes VSIs have private IP addresses only. -
Each VSI is set up with the following three user IDs. For descriptions of the parameters, see Deployment values.
- root
- Use the sshkey (
vpc_sshkey_name
parameter) that you set up to log in (ssh) to the VSIs as root. - OS administrator (
vsi_os_admin_name
) - The default value for the OS administrator is
virtuser
. You can change the default value. Use thevsi_os_admin_password
parameter value to log in (ssh) as this user. - WebSphere administrator (
vsi_websphere_admin_name
) - The default value for the WebSphere administrator is
wsadmin
. You can change the default value. Use thevsi_websphere_admin_password
parameter value to log in (ssh) as this user.
-
OS administrator and WebSphere administrator have password-less sudo access enabled on all VSIs. For
WAS.Cell
, the OS administrator and WebSphere administrator also have password-less sudo access enabled among the VSIs. -
Several ports are opened by default. Depending on your scenario, you might need to open more ports for your application to work.
