Another question:
- A Role (sounds like we're moving away from that so I'll call it
Resource Category) can have multiple Node Profiles defined (assuming I'm
interpretting the + and the tabs in the Create a Role wireframe
correctly). But I don't see anywhere where a profile is selected when
scaling the Resource Category. Is the idea behind the profiles that you
can select how much power you want to provide in addition to how many
nodes?
Yes, that is correct, Jay. I mentioned that in walkthrough and in
wireframes with the note "More views needed (for deploying, scaling,
managing roles)".
I would say there might be two approaches - one is to specify which node
profile you want to scale in order to select how much power you want to add.
The other approach is just to scale the number of nodes in a role and
let system decide the best match (which node profile is chosen will be
decided on the best fit, probably).
Hmm i'm not sure i understand - what do you think by "best fit" here?
E.g. i have 32 GB RAM profile and 256 GB RAM profile in the compute role
(and i have unused machines available for both profiles), and i increase
compute node count by 2. What do i best-fit against?
(Alternatively, if we want to support scaling a role using just one
spinner, even though the role has more profiles, maybe we could pick the
"largest" profile with unused nodes available?)
I lean towards the first approach, where you specify what role and which
node profile you want to use for scaling. However this is just
introduction of the idea and I believe we can get answers until we get
to that step.
+1. I think we'll want the first approach to be at least possible (maybe
not default). As a cloud operator, when i want deploy 2 more compute
nodes, i imagine there are situations when i do care whether i'll get
additional 64 GB or additional 512 GB capacity.
