Hi all,
One of our long mooted tags has been something that captures the ease of
upgrade for a service.
We've got a lot of inherit knowledge about this stuff that would be
great to capture, for example:
* Swift just eats upgrades up - whether you go for every point release,
or do the N to N+1 jump, provided you read the release notes it's
basically always a good time with Swift.
* Nova's upgrade_levels is pretty amazing, too. In recent versions you
can run N+1 apis with a mix of N and N+1 compute nodes - quite convenient.
* Neutron in some configurations dumps all of the flows, you have to
watch dhcp timeouts, how long services are offline etc, so a few little
traps that keep it from being perfect.
If we could somehow make this into a tag, that'd be great. Anyone want
to have a go?
Regards,
Tom
