Role-based HA management is important to ensure that high-priority applications remain available and continue to perform optimally. This requires application deployment with proper understanding of application, user load, connected devices, and priorities. There are several ways to address the needs for role-based HA management.
- Based on the prioritized grouping of the application components of this solution, a separate set of VMs can be used for deployment. Such physical separation allows configuration of a different set of policies to ensure higher availability. DVD application VMs can be configured with specific host rules to ensure consistency of performance and availability across all application components.
- Such role-based configurations determine the configuration needs of the additional level of clusters for VxRail and DVD applications. Clusters are complex to configure and manage, resource-intensive, and they can only be configured for high-priority applications and not for all applications.
- Similarly, backup and recovery can also be employed differently when considering role-based availability of DVD applications.
