This SIG aims to coordinate the use and development of several OpenStack projects which can be combined in various ways to manage OpenStack infrastructure in a policy-driven fashion, reacting to failures and other events by automatically healing services.
One of the biggest promises of the cloud vision was the idea that all the infrastructure could be managed in a policy-driven fashion, reacting to failures and other events by automatically healing and optimising services. Most of the components required to implement such an architecture already exist within OpenStack:
- HA of individual services
- Monasca: monitoring
- Aodh: alarming
- Congress: policy-based governance
- Mistral: workflow
- Senlin: clustering service
- Vitrage: root cause analysis
- Watcher: optimization
- Masakari: compute plane HA
- Freezer-dr: compute plane HA
- Heat: orchestration (normally used for cloud applications, but can also deploy cloud infrastructure via TripleO)
- Doctor: fault management and maintenance for NFV
- Fault Genes Working Group: Fault classification & Recovery Strategy
- Craton: Fleet management
- Kolla： Containerized OpenStack deployment tool
- kolla-k8s: same as above but in kubernetes cluster
However, there is not yet a clear strategy within the community for how these should all tie together. This SIG aims to address that.
The original proposal defined the SIG's scope as self-healing of cloud infrastructure, so for now it is primarily of interest to developers and operators, not end users. However it is also possible that in the future we will extend the scope to self-healing of cloud applications (e.g. see https://www.openstack.org/videos/barcelona-2016/building-self-healing-applications-with-aodh-zaqar-and-mistral), in which case end users could also find the SIG useful.
The scope could encompass not only self-healing of failures and service degradations, but also automatic optimization such as that performed by Watcher. However this would raise the issue that the name "self-healing" is not perfect because "healing" implies something is sick/broken, and optimization occurs even when the cloud is perfectly healthy. At the Sydney Forum session it was decided that it was better to be pragmatic and start small by focusing on hard failures. Optimization can easily be introduced later if required.
- Document reference stacks describing what use cases can already be addressed with the existing projects. (Even better if some of these stacks have already been tested in the wild.)
- Document what integrations between the projects already exist at a technical level.
- Collect real-world use cases from operators, including ones which they would like to accomplish but cannot yet.
- From the collected use cases, perform gaps analysis to help shape the future direction of these projects, e.g. through specs targetting those gaps.
- Perform overlap analysis to help ensure that the projects are correctly scoped and integrate well without duplicating any significant effort.
- Ensure that operators and developers are connecting on this topic on a regular basis, so that project development is steered in directions which will meet real-world requirements.
- Developers working on the OpenStack projects listed above
- Architects responsible for designing OpenStack deployments
- Operators responsible for deploying and managing OpenStack
As the scope increases in the future, we may also want to include:
- Architects responsible for designing applications which run on OpenStack clouds
- Developers responsible for developing applications which run on OpenStack clouds
- End users of applications which run on OpenStack clouds
- Adam Spiers
- Co-lead: Eric Kao
- Wiki: this page
- openstack-sigs mailing list; use the
- StoryBoard project
- IRC channel: #openstack-self-healing on Freenode IRC
- IRC meetings: TBD, #openstack-self-healing; agenda / details to be linked on SIG page + meetings list
There is a BoF session scheduled for the Vancouver Forum on Thursday, May 24, 1:50pm-2:30pm. Topics are being captured in the YVR-self-healing-brainstorming etherpad.

The idea for the SIG was born out of long-standing efforts to unify the OpenStack HA community around a single solution for instance HA, coupled with the realisation that this was just one of many self-healing use cases required in order for OpenStack infrastructure to be robust and performant.
A longer description of the history is in this blog post.
