Visual workflow management method for tracking work progress. Like having a board with columns showing what needs to be done, what's in progress, and what's completed.
Support teams use Kanban boards to track customer issues from 'New' to 'In Progress' to 'Resolved' columns.
Kanban is a methodology and not a specific cloud service, so there are no direct equivalents in cloud service providers. However, many cloud-based project management tools like Jira or Trello offer Kanban-style boards.
