Yeah, but do they do rolling restart or vertical scaling? I'm unaware of

any. A blue-green deploy to boost RAM is definitely an option, but it seems
like over kill, especially if you're already using a blue-green pattern to
maintain the ability to roll back a version (as now the scale change would
take up one of your "versions").
I don't actually know if the current CC API makes rolling scales possible
from the client side, plugin or no. Might the V3 API offer something around

In https://docs.cloudfoundry.org/devguide/deploy-apps/cf-scale.htmlJust an FYI, there are plugins that do automated blue-green deploys, such
there is no mention that vertical scaling requires a restart of all
application instances. At least in v220/dea_next cf scale -m and -k will
restart all instances.
I think it would be a good idea to have the documentation explicitly
state that vertical scaling will cause application downtime.
I was also wondering whether there is already a story about making all cf
scale operations not require a full restart (but rather a rolling restart,
ideally having new instances start before old ones are stopped) - this
looks to me something that shouldn't need to require a "manual" blue-green
as autopilot and cf-blue-green-deploy.
