Many look to the early 1970s for meaningful beginnings in distributed operating system research. These complete in definition and capability of being considered and implemented wholly. Research and experimentation efforts did began in earnest in the 1970s and continued through 1990s, with focused interest peaking in the late 1980's. A number of distributed operating systems were introduced during this period; however, very few of these implementations achieved modest commercial success.
The subject of distributed operating systems however, has a much richer historical perspective. This is especially evident when considering distributed operating system design issues severally, and with respect to some of the primordial strides taken towards their realization. There are [[#Pioneering_inspirationsHistorical_perspectives|several instances of fundamental and pioneering implementations of primitive distributed operating system component concepts]] dating back to the early 1950s.<ref name=dyseac>Leiner, A.

These pioneering efforts laid important groundwork, and inspired continued research in areas related to distributed computing.
Begining in the mid 1970's, many important research efforts produced extremely important advances in distributed computing. These breakthroughs provided a solid, stable foundation for the continued efforts through the 1990's, mentioned earlier. Considering the modern distributed operating system and its forfuture, one must look no further than the current incredible challenges of many-core and multi-processor science. The accelerating proliferation of multi-processor and multi-core processor systems research has led to a resurgence of the distributed operating system concept. Many of these research efforts are investigating interesting, exciting, and plausible paradigms impacting the future of distributed computing.
