Overview of the Visual Workflow life cycle
Cloud Flow Designer is a tool for creating flows, configuring screen elements, and defining business logic for your flows without writing code. Visual Workflow has three different stages, which are as follows:
Design: This allows you to create a flow using Flow Designer, which has a drag and drop user interface that allows you to draw the flow structure and configure how it would run, without writing code.
Administration: Once you have developed a flow, you can manage it, update its properties, activate it, deactivate it, delete it, save it as a new version or new flow, or run it.
Runtime: A flow user can run the active version of a flow from a custom button, link, and Visualforce Page or directly from the flow URL. If it is an autolaunched flow, then systems can run an active version of the flow through Process Builder, an Apex class.
