Towards a Prime Directive of SLOs

The promises of the computing continuum paradigm motivate a paradigm change for Internet-distributed computing systems. Unfortunately, we are still far from being able to develop computing continuum systems. We try to move one step forward in the direction of the computing continuum systems by defining design phases for the interconnection of the application with its underlying infrastructure. We assume that SLOs are critical to that endeavor. Hence, we analyze its usage in the scientific literature. Based on the learnings obtained, we define 9 design phases to provide homogeneity and common behaviors in large-scale, heterogeneous, distributed, and complex systems.
