I'm trying out Ubuntu cloud infrastructure in a lab environment, I had couple attempts and fails mostly because my references are outdated. "My main ref. now is https://help.ubuntu.com/community/UbuntuCloudInfrastructure"
My lab consists of three powerful servers, 3 low PCs, and 4 notebooks.
Constrains: Due to diversity in resources. I tried to selectively direct juju to deploy services by commissioning the low nodes first then bootstrap/deploy the needed service. But I saw in another ticket here that I can do that by specifying constrains. Is there a reference/ticket/how to article for that?
Consolidation: As jitsu is obsolete, and juju deploy to still consumes whole nodes for low services, I think add-node is the best alternative, yet again I lack the proper documentation to try this.
So I guess I'm asking for some demo case studies or best practices guides from the experts.
