Architecture Overview
|
||||
---------------------
|
||||
|
||||
* :doc:`Nova architecture </user/architecture>`: An overview of how all the parts in
|
||||
nova fit together.
|
||||
|
||||
* :doc:`Block Device Mapping </user/block-device-mapping>`: One of the more
|
||||
complicated parts to understand is the Block Device Mapping parameters used
|
||||
to connect specific block devices to computes. This deserves its own deep
|
||||
dive.
|
||||
|
||||
* :doc:`Conductor </user/conductor>`: TODO
|
||||
|
||||
Deployment Considerations
|
||||
-------------------------
|
||||
|
||||
There is information you might want to consider before doing your deployment,
|
||||
especially if it is going to be a larger deployment. For smaller deployments
|
||||
the defaults from the :doc:`install guide </install/index>` will be sufficient.
|
||||
|
||||
* **Compute Driver Features Supported**: While the majority of nova deployments use
|
||||
libvirt/kvm, you can use nova with other compute drivers. Nova attempts to
|
||||
provide a unified feature set across these, however, not all features are
|
||||
implemented on all backends, and not all features are equally well tested.
|
||||
|
||||
* :doc:`Feature Support by Use Case </user/feature-classification>`: A view of
|
||||
what features each driver supports based on what's important to some large
|
||||
use cases (General Purpose Cloud, NFV Cloud, HPC Cloud).
|
||||
|
||||
* :doc:`Feature Support full list </user/support-matrix>`: A detailed dive through
|
||||
features in each compute driver backend.
|
||||
|
||||
* :doc:`Cells v2 Planning </user/cellsv2_layout>`: For large deployments, Cells v2
|
||||
allows sharding of your compute environment. Upfront planning is key to a
|
||||
successful Cells v2 layout.
|
||||
|
||||
* :doc:`Placement service </user/placement>`: Overview of the placement
|
||||
service, including how it fits in with the rest of nova.
|
||||
|
||||
* :doc:`Running nova-api on wsgi </user/wsgi>`: Considerations for using a real
|
||||
WSGI container instead of the baked-in eventlet web server.
|
||||
|
||||
Maintenance
|
||||
-----------
|
||||
|
||||
Once you are running nova, the following information is extremely useful.
|
||||
|
||||
* :doc:`Admin Guide </admin/index>`: A collection of guides for administrating
|
||||
nova.
|
||||
|
||||
.. warning::
|
||||
|
||||
This guide was imported during the Pike cycle and is a bit out of
|
||||
date. It will be updated during Queens to be more accurate.
|
||||
|
||||
* :doc:`Upgrades </user/upgrade>`: How nova is designed to be upgraded for minimal
|
||||
service impact, and the order you should do them in.
|
||||
|
||||
* :doc:`Quotas </user/quotas>`: Managing project quotas in nova.
|
||||
|
||||
* :doc:`Aggregates </user/aggregates>`: Aggregates are a useful way of grouping
|
||||
hosts together for scheduling purposes.
|
||||
|
||||
* :doc:`Filter Scheduler </user/filter-scheduler>`: How the filter scheduler is
|
||||
configured, and how that will impact where compute instances land in your
|
||||
environment. If you are seeing unexpected distribution of compute instances
|
||||
in your hosts, you'll want to dive into this configuration.
|
||||
|
||||
* :doc:`Exposing custom metadata to compute instances </user/vendordata>`: How and
|
||||
when you might want to extend the basic metadata exposed to compute instances
|
||||
(either via metadata server or config drive) for your specific purposes.
