In an attempt to make the main navigation sidebar not be visual mud (and really confusing) create a reference sub page that explains all the references. Part of bp: doc-migration Change-Id: I005fc24e49487631d7fe73cb498c61619bcaac9d

Technical Reference Deep Dives
|
|
================================
|
|
|
|
The nova project is large, and there are lots of complicated parts in it where
|
|
it helps to have an overview to understand how the internals of a particular
|
|
part work.
|
|
|
|
Internals
|
|
=========
|
|
|
|
The following is a dive into some of the internals in nova.
|
|
|
|
* :doc:`/reference/rpc`: How nova uses AMQP as an RPC transport
|
|
* :doc:`/reference/services`: Module descriptions for some of the key modules
|
|
used in starting / running services
|
|
* :doc:`/reference/vm-states`: Cheat sheet for understanding the life cycle of
|
|
compute instances
|
|
* :doc:`/reference/threading`: The concurrency model used in nova, which is
|
|
based on eventlet, and may not be familiar to everyone.
|
|
* :doc:`/reference/notifications`: How the notifications subsystem works in
|
|
nova, and considerations when adding notifications.
|
|
|
|
Debugging
|
|
=========
|
|
|
|
* :doc:`/reference/gmr`: Inspired by Amiga, a way to trigger a very
|
|
comprehensive dump of a running service for deep debugging.
|
|
|
|
Forward Looking Plans
|
|
=====================
|
|
|
|
The following section includes documents that describe the overall plan behind
|
|
groups of nova-specs. Most of these cover items relating to the evolution of
|
|
various parts of nova's architecture. Once the work is complete,
|
|
these documents will move into the "Internals" section.
|
|
|
|
If you want to get involved in shaping the future of nova's architecture,
|
|
these are a great place to start reading up on the current plans.
|
|
|
|
* :doc:`/user/cells`: Comparison of Cells v1 and v2, and how v2 is evolving
|
|
* :doc:`/reference/policy-enforcement`: How we want policy checks on API actions
|
|
to work in the future
|
|
* :doc:`/reference/stable-api`: What stable api means to nova
|
|
* :doc:`/reference/scheduler-evolution`: Motivation behind the scheduler /
|
|
placement evolution
