Etherpad notes<br>
<br>
<br>
This Etherpad is for the<br>
Discussion on Design & Software Considerations for Making Nova HA/Fault Tolerant<br>
Please put ideas or comments in the appropriate sections<br>
<br>
<br>
Database<br>
- Does zones alleviate the need for HAing the DB?<br>
<br>
<br>
<br>
RabbitMQ<br>
For comparison <a href="http://wiki.secondlife.com/wiki/Message_Queue_Evaluation_Notes" target="_blank">http://wiki.secondlife.com/<u></u>wiki/Message_Queue_Evaluation_<u></u>Notes</a><br>
- Need to update managers to create persistant queues and messages<br>
- XMPP an alternate?<br>
Talk to RabbitMQ devs about<br>
- Long term can we use Burrow?<br>
<br>
<br>
Nova-Network<br>
NTT Data documentation mailed to openstack list for their heartbeat POC tests<br>
Are there issues running multiple network nodes and assigning the same IP to mutlple instances?<br>
How about VRRP protocol?<br>
--> we (NTT) are planning to evaluate VRRP using keepalived or some other software. Does anyone knows suitable software?<br>
<br>
<br>
Nova-scheduler<br>
Vish said you can run more then one<br>
- Yeah with zones and how the scheduler is structured now, it can<br>
<br>
<br>
Nova-api<br>
Possibliy to run this behind real web server, apache, nginx<br>
<br>
<br>
Nova-volume<br>
<br>
Nova-Objectstore<br>
<br>
Nova-Compute<br>
<br>
<br>
Other ideas<br>
Services should use dns srv records or something to automate service discovery, this would make running large infrastructures and ipv6 configureation alot easier.<br>
- zeroconf? -<-- like the idea but anyone can announce anything in zeroconf it has no idea of a master for security.<br>
Agreed<br>
Look at vrrp and keepalived<br>
<br>
<br>
Take aways<br>
Start Discussion with Rabbitmq<br>
Message Bus needs more investigation<br>
Discussion on how do we make messages have delievery<br>
Give feed back to end user, fail or pass just dont leave state in pending forever<br>
