      Before you begin installing Workflow, it is important to determine your architecture so you can know where to install your servers.
      - One Cluster, Two Nodes
        One of the environments supported and validated for server clustering is a single cluster with two nodes.
      - Two Clusters, Two Nodes Each
        One of the environments supported and validated for server clustering is two clusters with two nodes each.

    - Microsoft Failover Cluster Manager for Windows Servers
      The Microsoft Failover Cluster Manager is used to create the cluster and to add nodes to the cluster.
    - Install Microsoft Failover Cluster Manager
      The Microsoft Failover Cluster Manager must be installed in order to configure your failover cluster.
    - Configure the Microsoft Failover Cluster Manager
      The Microsoft Failover Cluster Manager is used to create a new DNS entry to manage your server cluster.
    - Configure quorum options for a cluster
      Although this application does not require a disk for clustering, it is recommended that you configure either a file share witness or a disk witness.
    - Configure the primary cluster server
      After installing the application server on your primary server machine, you must configure the machine as the primary cluster server to begin the clustering process.
    - Configure the failover cluster server
      After configuring the primary application server cluster server and exporting the server security certificates, you can configure the failover cluster server.
    - Configure a local client for a cluster node (32-bit)
      If you want to run a cluster node on a 32-bit system, follow this procedure.
    - Configure a local client for a cluster node (64-bit)
      If you want to run a cluster node on a 64-bit system, follow this procedure.
    - Server Clustering and One-Click Deployment
      If you have implemented a server cluster environment and you want to use one-click deployment in that environment, additional configuration is required to set up the one-click deployment.

Three Clusters, Two Nodes Each

One of the environments supported and validated for server clustering is three clusters with two nodes each.

The following figure shows an example of two application servers, two Workflow engines, and two User servers, each in its own cluster. Each application server must run the Proficy Server, Proficy Publisher Service, and Proficy STS services. Each Workflow engine and each User server must run the Proficy Server service.
