Goutham Pacha Ravi dfbe3ea418 In-tree Install Guide 
The OpenStack install guide team has recommended that projects
that are not part of the starter-kit:compute [1] (and a few other projects
like Cinder and Horizon) maintain their install guide in-tree. [2]

Shared File Systems service overview

The OpenStack Shared File Systems service (manila) provides file storage to a virtual machine. The Shared File Systems service provides an infrastructure for managing and provisioning of file shares. The service also enables management of share types as well as share snapshots if a driver supports them.

The Shared File Systems service consists of the following components:

manila-api

A WSGI app that authenticates and routes requests throughout the Shared File Systems service. It supports the OpenStack APIs.

manila-data

A standalone service whose purpose is to receive requests, process data operations such as copying, share migration or backup, and send back a response after an operation has been completed.

manila-scheduler

Schedules and routes requests to the appropriate share service. The scheduler uses configurable filters and weighers to route requests. The Filter Scheduler is the default and enables filters on things like Capacity, Availability Zone, Share Types, and Capabilities as well as custom filters.

manila-share

Manages back-end devices that provide shared file systems. A manila-share process can run in one of two modes, with or without handling of share servers. Share servers export file shares via share networks. When share servers are not used, the networking requirements are handled outside of Manila.

Messaging queue

Routes information between the Shared File Systems processes.
