The cloud based smart classroom helps in teaching, learning and assessment methods. This paper proposes taxonomy of each education system processes namely teaching, learning, assessment and school management prevalent presently with underlying communication process based on social support and persuasive theories. Learning and Teaching Expo of Hong Kong during December 2014 helped to test the propositions that education cloud provides social support (P1), persuasive support (P2) and social persuasive support (P3) and to come up with the taxonomy of education cloud and processes involved. This case study was done by visiting the expo, seeing demonstrations, interviewing the educational product providers and analyzing secondary data provided by them through pamphlets and websites. The designed taxonomy will help all stakeholders of educational institutions to classify the education cloud environment. The stakeholders could consider the features that meet their needs and implement the educational processes efficiently.
