Veritas Resiliency Platform 1.1: Using virtual business services

 

Any business service is typically made up of multiple components, databases, applications, and web servers. For a business service to work properly, all of its tiers and components must be up and working together. Tiers represent the logical dependencies between the resiliency groups and determine the relative order in which the resiliency groups start and stop. To ensure business continuity, make sure that not just the individual tiers are up and running but also the entire business service.

For example, a payroll business service might include a web server, a database, and a payroll application. The payroll application requires the web server, application, and the database to be up and running to provide payroll service. Even if one component were down, the payroll service would be down. From a business perspective, the payroll service is unavailable without the web server and the database also being available. The logical dependencies between the parts of the business service determine the relative order in which they must start and stop to continue to provide the service.

A virtual business service (VBS) is a multi-tier business service.

In Veritas Resiliency Platform, a VBS lets you group multiple services as a single unit for visualization, automation, recovery, and controlled start and stop in the desired order.

A VBS is composed of resiliency groups, the unit of management and control in Resiliency Platform. You organize related assets into a resiliency group and manage and monitor them as a single entity.

Within a VBS, resiliency groups are arranged in tiers. Tiers represent the logical dependencies between the resiliency groups and determine the relative order in which the resiliency groups start and stop.

For example, you can group a web server resiliency group, a database resiliency group, and a payroll business logic resiliency group into a VBS called payroll. The database resiliency group must start first, so the database resiliency group must go in the lowest tier. The application server resiliency group must start after the database resiliency group, so it goes in the next tier. The web server resiliency group must start last, so it goes into the top tier. 

The Resiliency Platform console lets you create a VBS by dragging and dropping resiliency groups into tiers. The console also includes a graphic representation of the order in which they start and stop.

Creating a virtual business service

Resiliency Platform also lets you customize a VBS to speed up start and stop operations of the resiliency groups within it if some dependencies are not required.
