Service infrastructure for collecting data via networks and constructing computing resources such as IoT and big data is rapidly spreading. This is a service form that has further evolved the infrastructure in which networking and computing have been integrated recently called cloud and is realized by combining software components present on the network and computational resources virtualized by software ing.
Therefore, in this lecture we will review the basics of conventional network technology and computing technology, and acquire elemental technologies of infrastructure built across both fields based on that knowledge.
