Plan your suite deployment
The Container Deployment Foundation allows you to deploy a suite in an environment that is comprised of one or multiple master nodes and multiple worker nodes for load balancing and failover purposes. Client requests are sent to the load balancer, which redirects the requests to the master nodes, and the master nodes then sends the requests to the worker nodes.
To plan your suite deployment, review the support matrix, the supported configurations, and the ITOM CDF configuration parameters.
Review the support matrix
- Download the Support Matrices for Operations Center products.
- Open SUMA.htm and select Operations Bridge Suite (container deployment) from the product list.
The master node and each worker node must run one of the operating systems listed when filtering for the Container Host component.
Decide your deployment mode
Master nodes coordinate all activity in your cluster, such as scheduling applications, maintaining applications' desired state, scaling applications, and rolling out new updates. Worker nodes run the applications. A node is a VM or a physical computer that serves as a worker machine in a Kubernetes cluster.
A Kubernetes cluster that handles production traffic should have a minimum of one master and three worker nodes. By deploying multiple master and worker nodes, you can make your system highly available. For more information, see the Kubernetes HA documentation.
The Operations Bridge Suite uses NFS to store run time, configuration, and log data. You can use a separate NFS server, or use a master node as NFS server.
Additionally, the suite uses databases for the CDF and for the suite components. You can use embedded databases that run in containers, or you can connect to externally installed databases.
Single node
In a testing environment, you can use one system as master and worker node (single node deployment) with the system also serving as NFS server.
Single master multi-worker deployment
You can use one master node and multiple worker nodes to have multiple nodes on which you can run the capabilities' workloads on. You can decide if you want to use a separate NFS server, or if you want to use the master node as NFS server.
Multi-master multi-worker deployment
In a production environment, you use multiple master nodes, multiple worker nodes, and (highly recommended) a separate NFS server.
