The evolution of distributed computing
and applications has put new challenges on models, architectures and systems.
To name just one, ‘reconciling uncertainty with predictability’ is
required by today’s simultaneous pressure on increasing the quality of
service of applications, and on degrading the assurance given by the
infrastructure. This challenge can be mapped onto more than one facet, such as
time or security or others. In this paper we explore the time facet, reviewing
past and present of distributed systems models, and making the case for the use
of hybrid (vs. homogeneous) models, as a key to overcoming some of the
difficulties faced when asynchronous models (uncertainty) meet timing
specifications (predictability). The Wormholes paradigm is described as the
first experiment with hybrid distributed systems models.
