Evaluation

• scalability: Figures 8-10 show scalability of application based on number of nodes. extrapolation claims valid?

• high availability (Fig 11)

• graceful degradation (Fig 12) Nice performance graph.

• online evolution. Fig 13 shows changeover.

• range of semantics---have used the range!

• service authoring---code sizes in Fig 14. Better when compared to Porcupine mail service. Found event-based programming harder than threads! internal authors!
