Architecture Overview

The application has the following main components.

• Frontend application: This is the end user visual designer, enabling no-code Workflow building, as well as the ability to see and manage all aspects of your Workflows, including activity and insights.
• Backend for frontend (BFF) microservice: This component translates the requests from the Front End application.
• Engine microservice: This component manages the DAG lifecycle and trigger interactions.
• Handler microservice: The Handler integrates with Kubernetes^® and Tekton and is responsible for managing the execution of the Tasks, including the orchestration of the TaskRuns and the management of the TaskRun lifecycle.
• Tasks: The Task workers are containers used to execute the tasks mapped in the Workflow using Tekton^® TaskRuns

Execution

The default handler executing the tasks within the DAG as part of the Workflow, relies on Tekton TaskRuns and Kubernetes to perform the execution of the Tasks that are a part of the the Workflow or Directed Acyclic Graph (DAG).

The default Handler could be replaced with a custom Handler, executing the tasks against a different cloud provider, for example Azure Container Apps.

Tasks

There are a number of different types of Tasks including pre-built Tasks designed for a no-code experience. These are single-focus Tasks that offer tight integration into the platform, with certified Tasks providing a guaranteed implementation and tested experience.

See Getting to Know Tasks to learn more.

Bring Your Own Container Task

The Bring Your Own Container Task is a special type of System Task where you can bring your own container and run that as a Task. Typically, the Custom Task has no knowledge or understanding of integrating with Boomerang Flow and we do not force adherence to a specific implementation. The Custom Task is denoted by a flag in the upper left corner of the Task in the Workflow Editor and Workflow Run pages.
