  Cloud services today are increasingly built using functionality from other
running services. In this paper, we question whether legacy Quality of Services
(QoS) metrics and enforcement techniques are sufficient as they are producer
centric. We argue that, similar to customer rating systems found in banking
systems and many sharing economy apps (e.g., Uber and Airbnb), Quality of
Consumption (QoC) should be introduced to capture different metrics about
service consumers. We show how the combination of QoS and QoC, dubbed QoX, can
be used by consumers and providers to improve the security and management of
their infrastructure. In addition, we demonstrate how sharing information among
other consumers and providers increase the value of QoX. To address the main
challenge with sharing information, namely sybil attacks and mis-information,
we describe how we can leverage cloud providers as vouching authorities to
ensure the integrity of information. We present initial results in prototyping
the appropriate abstractions and interfaces in a cloud environment, focusing on
the design impact on both service providers and consumers.
