Mistral Architecture
====================
Mistral is OpenStack workflow service. The main aim of the project is to provide
capability to define, execute and manage tasks and workflows without writing
code.

Workflow Service Overview
=========================
Mistral is a workflow service that enables setting up and scheduling tasks and
task relations that have to be executed in a particular order, called workflows.
During execution, Mistral handles state management, correct execution order,
parallelism, synchronization and high availability.
Mistral can be used, for example, for Cloud Cron-style task scheduling,
Cloud Environment Deployment, handling long-running business processes, managing
BigData analysis and tasks, and live migration.
The Workflow service consists of the following components:

What is Mistral?
================
Mistral is a workflow service project. It aims to provide a mechanism
to define complex graphs of tasks (workflows) in a simple YAML-based
language and manage and run them in a scalable and reliable manner.
Mistral is a workflow service. Lots of computations in computer systems
nowadays can be represented as processes that consist of multiple
interconnected steps that need to run in a particular order. Those steps
are often interactions with components distributed across different machines:
real hardware machines, cloud virtual machines or containers. Mistral provides
capabilities to automate such processes.
Particularly, Mistral can be used, for example, for solving administrator
tasks related to managing clusters of software, or for any other tasks
that span multiple components and take long to complete. It can also be used
as a central component for deploying distributed software in a truly large
scale. In any case where the ability to track the progress of the activity
becomes crucial, Mistral is a good fit.
A Mistral user can describe such a process as a set of tasks and transitions
between them, and upload such a definition to Mistral, which will take care of
state management, correct execution order, parallelism, synchronization and
high availability. In Mistral terminology such a set of tasks and
relations between them is called a **workflow**.

Quick Overview
==============
What is Mistral?
----------------
Mistral is a workflow service. Most business processes consist of multiple
distinct interconnected steps that need to be executed in a particular order
in a distributed environment. A user can describe such a process as a set of
tasks and their transitions. After that, it is possible to upload such a
description to Mistral, which will take care of state management, correct
execution order, parallelism, synchronization and high availability. Mistral
also provides flexible task scheduling so that it can run a process according
to a specified schedule (for example, every Sunday at 4.00pm) instead of
running it immediately. In Mistral terminology such a set of tasks and
relations between them is called a **workflow**.
