CONCLUSIONS

Energy Efficiency in Cloud Software Architectures

Our codes allow to describe Cloud Software Architectures from an Energy Efficiency perspective.

However, components devoted to balance the trade-off between EE and other system qualities were found frequently.

No architectures defining EE as a SLO were found.
