What is a Node?

A node is a basic element of the TotalCloud workflow that performs specific functions. You can define these nodes with the help of conditions and filters. They are available in the Workflow Editor.

While choosing the nodes, think of the sequence of actions you will undertake while using the AWS CLI or the console. This will help you quickly decide on the type of nodes you will need for a workflow.
