Scheduler agent supervisor pattern

This Azure cloud architecture pattern diagram template was created on the base of figure in the article "Scheduler Agent Supervisor Pattern" from the Microsoft Developer Network (MSDN) website.
"Scheduler Agent Supervisor Pattern.
Coordinate a set of actions across a distributed set of services and other remote resources, attempt to transparently handle faults if any of these actions fail, or undo the effects of the work performed if the system cannot recover from a fault. This pattern can add resiliency to a distributed system by enabling it to recover and retry actions that fail due to transient exceptions, long-lasting faults, and process failures. ...
An application performs tasks that comprise a number of steps, some of which may invoke remote services or access remote resources. The individual steps may be independent of each other, but they are orchestrated by the application logic that implements the task.
Whenever possible, the application should ensure that the task runs to completion and resolve any failures that might occur when accessing remote services or resources. ...
If the application detects a more permanent fault from which it cannot easily recover, it must be able to restore the system to a consistent state and ensure integrity of the entire end-to-end operation. ...
The Scheduler Agent Supervisor pattern defines the following actors. These actors orchestrate the steps (individual items of work) to be performed as part of the task (the overall process):
- The Scheduler arranges for the individual steps that comprise the overall task to be executed and orchestrates their operation. ...
- The Agent contains logic that encapsulates a call to a remote service, or access to a remote resource referenced by a step in a task. ...
- The Supervisor monitors the status of the steps in the task being performed by the Scheduler. ...
The Scheduler, Agent, and Supervisor are logical components and their physical implementation depends on the technology being used." [msdn.microsoft.com/ ru-RU/ library/ dn589780.aspx]

"Time management is the .. process of planning and exercising conscious control over the amount of time spent on specific activities, especially to increase effectiveness, efficiency or productivity. Time management may be aided by a range of skills, tools, and techniques used to manage time when accomplishing specific tasks, projects, and goals complying with a due date. Initially, time management referred to just business or work activities, but eventually the term broadened to include personal activities as well. A time management system is a designed combination of processes, tools, techniques, and methods. Time management is usually a necessity in any project development as it determines the project completion time and scope." [Time management. Wikipedia]
This timetable pie chart shows the plan of daily actions and its durations in minutes.
It is useful visual tool of personal time management.
This schedule pie chart example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Target and Circular Diagrams solution from the Marketing area of ConceptDraw Solution Park.
