Recovery of Multi-tier Applications managed with Virtual Business Services in Veritas Operations Manager
In a multi-tier business service, different tiers usually have different requirements. One tier may require full-fledged high availability with split-second error detection and fast failover, while other tiers just need basic start and stop capability. The management of start and stop for any service is critical to successful recovery. Business services have strict start and stop orders that need to be validated before proceeding to the next service. Often times, these services are managed by different IT teams. The actual start/stop command for each tier may be simple, but given the amount of coordination, communication, validation and handover between the different teams, the process can be time consuming.
The Red Hat Enterprise Virtualization environment with Cluster Server can be managed with Veritas Operations Manager (VOM), which provides a centralized console to monitor, visualize, and configure all resources. VOM also provides a view into every level of the IT infrastructure from the application to the disk drives. It provides a consistent Graphical User Interface (GUI) and Command Line Interface (CLI) driven administration across all platforms: Red Hat Enterprise Virtualization, Red Hat Enterprise Linux, VMware, UNIX and Windows. VOM reports on the relationship of applications to virtual machines, physical servers and clusters. Many organizations use different staff to manage servers, SAN and storage connectivity, storage and applications. These organizations benefit from this unified view that can administer server clusters and HA/DR configurations from this single console view.
