High availability deployment for production

Consider these best practices when planning for high availability (HA) in your deployment.

High availability overview

The application employs a standard three-tier architecture: client, application server, and database. Clients include smartphones, tablets, laptops, and desktops.

To achieve high availability, you can use multiple servers for each server and database component, and load balancers where needed. For BMC Digital Workplace server, the server grouping is a cluster. For AR System server with Remedy ITSM, the server grouping is a server group. The following diagram illustrates the communication between components in a typical production deployment for BMC Digital Workplace Basic. This diagram does not include either BMC Virtual Chat or BMC Digital Workplace Catalog , both of which are included with BMC Digital Workplace Advanced.

Deployment architecture diagram

To simplify the diagram, BMC Remedy Single Sign-On (BMC Remedy SSO) is not included. 

BMC Digital Workplace integrates with other systems by using a variety of providers. The application can expose aspects of other IT applications through the UI, or it can use other applications to aid or enhance core BMC Digital Workplace functionality. For example, BMC Digital Workplace integrates with modules in BMC Remedy IT Service Management (Remedy ITSM) to submit service requests and to search for knowledge articles. Providers handle integrations with BMC Digital Workplace.

Clusters and server groups

For high availability and performance, each type of server should be set up as a cluster behind a load balancer. For Remedy servers, these clusters are referred to as server groups.

Remedy Single Sign-On

The following diagram provides an overview of the RSSO architecture. 

For more information about RSSO, see the following topics in the Remedy Single Sign-On documentation:

  • Remedy SSO overview
  • Remedy SSO architecture
  • Integrating Remedy SSO with BMC Digital Workplace

Communication to external networks

Communication to an external network is required for the following capabilities:

  • Notification to mobile clients - Google cloud messaging provides notifications to Google Android devices. Apple Push Notification Service (APNS) provides notifications to Apple iOS devices.
  • Location awareness - Google Maps APIs provide the geographic maps displayed on all clients.

If you do not use either notification to mobile clients or location awareness, your deployment can remain fully within your internal network. For details about ports used for communication, see Required ports.

BMC Digital Workplace mobile applications

A native mobile app for BMC Digital Workplace is available, which you can distribute to your users as described in Deploying clients. For more information about device compatibility, see System requirements. For more information about deploying a custom-branded app to your users, see Deploying clients.
