Its interesting to consider the shift from performance being a feeds and speeds discussion to more of one around expectations. Different people have different expectations and I think the list you outlined helps to cover the list of expectations from several perspectives.
.
Time to Deploy (Interested parties include developers as time to get new solutions up and running have a dramatic effect on a developer's productivity.)
.
Density (Interested parties: CIOs, Operations Mgmt, CTOs,mostly people interested in efficiency around investment. Meaning, are my dollars being used efficiently)
.
Elastic Scale (Interested Parties: Line of Business owners who sponsored and support the application being hosted. Does it meet my customer's expectation for response time, is it efficient so I don't waste money).
.
Resiliency (Security/Isolation) (Interested Parties: who doesn't want good solid isolation and security. The challenge for us going forward is to measure the risk of high multi-tenant Platforms (running lots of users in the same VM / JVM) as opposed to high multi-tenancy via virtualization of many OS instances. There won't be one right answer for all).
.
Runtime Performance (Interested Parties: Everyone. Although this one get more complicated. Traditionally this drove a lot of discussion about speed but today, with heavy virtualization, to support a highly multi-tenant environment, we will need to start ordering which priorities mean more to us than others.
.
Time to Genesis - (Interested Parties: Cloud / Infrastructure providers) I think this includes not only the time to setup a new environment, lbut also the ability to scale the environment by adding more hardware (compute, net or storage) seamlessly.
.
Great start to looking at cloud metrics in a more meaningful way in the for of expectations.
