A Business Application is a set of interconnected applications, services and hosts, which are configured to offer a service to the organisation. Business Applications can be internal, like organization email system or customer-facing, like an organization website. The Business Applications page in vRealize Operations is where you see Business Applications and their health.
A Business Application is a container construct that represents a collection of interdependent hardware and software components that deliver a specific capability to support your business. You create a Business Application to determine how your environment is affected when one or more components in the Business Application experiences problems, and to monitor the overall health and performance of the Business Application. vRealize Operations can also display applications discovered through Service Discovery, and by importing applications from vRealize Network Insight.
