Mistral Workflow Service
|
|
========================
|
|
|
|
What is Mistral?
|
|
================
|
|
|
|
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**.
|
|
|
|
|
|
