Composite Applications

What is a Composite Application?

Composite Application is a logical container to group Azure Services like Service Bus, Logic Apps, Event Hubs, Event Grid, Azure Function Apps, etc that constitute a Line of Business Application in the Integration Solution Architecture. These resources can be from different Azure Subscriptions, Regions and namespaces.

With Azure becoming more mainstream and a matured product offering from Microsoft, many organizations have started to make use of the technology to build their hybrid integration solutions as an extension to their on-premise solution. The overall hybrid integration solution will look something like the image below.

Serverless360 can facilitate managing and monitoring this entire solution containing several Azure services (Service Bus, Event Hubs, Relays, Logic Apps, API Management, Functions etc) effortlessly in a Composite Application. Any typical organization will have several such Composite Applications. With the concept of Composite Applications. Even if your Azure services are spread across different Subscriptions, you can manage and monitor your services.
## What is a Composite Application Group?
An organisation may have multiple Business Units each consisting of multiple Business Orchestrations in turn. Here, the Business Orchestrations can be represented as Composite Applications and the Business Unit can be represented as a Composite Application Group. So, the Composite Application Group will include multiple the Composite Applications. It is also possible to create Composite Application Groups within a Composite Application Group.

Explorer View of Composite Applications

The relationship between the Composite Applications and Composite Application Groups will be represented in the Explorer view of Composite Applications in the Composite Applications dashboard. The status of a Composite Application will be represented using the status tags based on the monitoring status of the entities in it.
The status of the Composite application will be based on the following conditions

1. If all entities in the Composite Application are Healthy (Green), the Composite Application will be represented Healthy (Green)
2. If at least one entity in the Composite Application is in Warning state (Amber), the Composite Application will be represented Warning (Amber)
3. If at least one entity in the Composite Application is in Error state (Red), the Composite Application will be represented Error (Red)
