The aim of the group is to facilitate running OpenStack at large scale, answer questions that OpenStack operators have as they need to scale up and scale out, and help address some of the limitations operators encounter in large OpenStack clusters.

== The Scaling Journey ==
 
The work of the group is organized along the various stages in the scaling journey for someone growing an OpenStack deployment. That path was successfully traveled by many before, . The job of the SIG is to extract that knowledge and provide answers for those who come next.
 
 
 
For each step the SIG will collect frequently-asked questions and answers, articles, presentations. When documentation or tools are missing, we help to produce them.
 
 
 
==== Stage 1: Configure ====
 
Tune configuration options and optimize the parameters for your OpenStack cluster, so that it can handle additional load.
 
 
 
See [[Large_Scale_SIG/Configure]] for more details !
 
 
 
==== Stage 2: Monitor ====
 
Meaningful monitoring of your cluster to detect strain and limits.
 
 
 
See [[Large_Scale_SIG/Monitor]] for more details !
 
 
 
==== Stage 3: Scale up ====
 
As you reach those limits, what can be done to handle more load within one cluster.
 
 
 
See [[Large_Scale_SIG/ScaleUp]] for more details !
 
 
 
==== Stage 4: Scale out ====
 
Past a given scale, you will have to scale out to multiple clusters, regions, cells or zones. What are the available options?
 
 
 
See [[Large_Scale_SIG/ScaleOut]] for more details !
 
 
 
==== Stage 5: Upgrade and maintain ====
 
Once you have scaled out, how to do you effectively upgrade and maintain your deployment?
 
 
 
See [[Large_Scale_SIG/UpgradeAndMaintain]] for more details !
 
 
 
 
 
== ''Large Scale OpenStack'' show on OpenInfra Live ==
 
 
 
We are regularly producing a live show on https://openinfra.live , sharing experience from large scale OpenStack deployments and taking questions from the audience.
 
 
 
Past episodes:

== Other ==
 
 
 
==== Ceph and OpenStack ====
 
Ceph is very commonly associated with OpenStack, which raises a number of questions.
 
 
 
See [[Large_Scale_SIG/CephAndOpenStack]] for more details !
 
 
 
 
 
== Join the SIG! ==
 
The Large Scale SIG will use mostly asynchronous communications means: discussions on the [http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-discuss openstack-discuss mailing-list] using the [largescale-sig] prefix, and various etherpads. Occasionally we may leverage the #openstack-operators IRC channel for synchronous discussion.
 
 
 
==== IRC Meeting ====
 
The Large Scale SIG meets on IRC typically every two weeks:
 
* Current [http://eavesdrop.openstack.org/#Large_Scale_SIG_Meeting IRC meeting schedule]
 
* Propose [https://etherpad.openstack.org/p/large-scale-sig-meeting agenda items] for our next meeting
 
* Past meetings [http://eavesdrop.openstack.org/meetings/large_scale_sig/ summary and logs]
 
 
 
==== Live open discussions ====
 
In the past we had live open discussions in a video meeting around a specific topic. Thise were replaced by openInfra.live. Here are links to old videos:
