One of our long mooted tags has been something that captures the ease of upgrade for a service.<br>
<br>
We've got a lot of inherit knowledge about this stuff that would be great to capture, for example:<br>
<br>
* 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.<br>
* 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.<br>
* 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.<br>
<br>
If we could somehow make this into a tag, that'd be great. Anyone want to have a go?<br>
<br>
